loads for the 300 H & H

I am well aware of how my grandfather feels about this.

"The purpose of this caliber is so you can shoot 200 or 220 gr effectively, if you want to use 180 gr, use your 30-06 and if your going lighter than that use my 275 H & H "

The gun shoots 200 gr Swift A frames very well and I guess if its not broke, dont fix it. Plus, this is one of Aleenas favorite calibers and she also uses the heavier bullets but I think woodleigh and GSC

but I was curious---- what is the favorite loads of others who hunt with a 300 H & H. The gun will be used basically for antlered animals ( Deer, Elk, Moose, Caribou, Sheep, goat )
 
The 200 gr A Frame load would be great, although when I had a 308 Norma Mag the 220 gr Partition at 2700 fps was an absolute hammer or maybe throw everyone for a loop and load something like a 150 or 168 gr E Tip at high speed :)
 
I load 72.0gr RL22 under a 180gr Nosler Partition, and get 3015fps. No 30-06 will do that!

Fast, flat, and should knock the snot out of anything hooved at 500 yards or less.

No first hand experience with the 300 H&H but a 180 gr PT at 2900-3000 fps is some serious horse power.
It will shoot fairly flat and hit hard. More than enough for the game you are interested in hunting with your new 300 H&H.

Cheyenne, I used the 165 gr Partition for deer and the 180 Partition for elk in the .300 H&H. The loads were:
-165 Partition, W-W Brass, CCI 250 MM primer, 69.0 grs IMR 4350 powder, 3150 fps.
-180 Partition, W-W Brass, CCI 250 MM Primer, 67.0 grs IMR 4350 powder, 2960 fps.

My rifle was the Alaskan Model 70 with 25 inch barrel. These loads killed everything that I shot, DRT!
 
Whoa, only two people either had or have the 300 H & H I dont know if I should feel good about that or bad.

Right after we got the rifle my husband said--finally we can shoot something besides the 200 swift---

We will start with the mix from Tom as we have those ingredients and if that dont work we will try yours charlie

Gerry, if our grandfather ever found out we went down to 150 he would probably have a heart attack LOL

Jim, did you notice I didnt even get a full page of loads from Scotty or Fotis--like I said, I dont know if this caliber was a good idea or a bad idea LOL. Regardless, i love it and I think it will serve me well--thanks to all who responded
 
Cheyenne,

The good ol' 300 H&H was bumped to the side lines when the 300 Win Mag and 300 Wby were introduced. Marketing pushed the faster is better onto the shooting public. That is why there are not a lot of 300 H&H shooters anymore which is too bad. This is why you won't see a lot of fellas loading for the 300 H&H, they are loading for the 300 Win Mag, 300 Wby, 300 RUM and 300-378 Wby.

Don't second guess your decision on the 300 H&H, it is a solid choice. The 300 H&H is the reason why John Nosler designed the Partition bullet way back in 1948. Its also one reason I would pick the 180 gr PT, nostalgia. :grin:

Might try asking how many on here would love to own a 300 H&H, I certainly would as it will do everything you would ever want and IMO the cool factor is off the scale.
 
Cheyenne,

The 300 H&H is a fantastic cartridge. It has been shoved out by other 300s (300WM, 300 WBY and more recently the 300WSM), but that takes little away from it. It is not as commonly chambered in standard rifles. Here you go for the theoretical.

Yeah, without a doubt! It is actually part of the reason I got a 300 WSM. I wanted H&H ballistics, but a real H&H was out of reach for me. If I had the ability to get a H&H, I would have had one.

Mike laid out exactly what I would be trying to shoot in an H&H were I to have one. The 200 grain Nosler PT at around 2900! That would be FEARSOME on all game I think you would encounter Cheyenne. That is some serious HP near and far. RL22/25 look pretty darned good and man, that would be a super rifle. While the 180's would be awesome, I agree with your grandfather, the 300 magnums were meant to push the heavy bullets FAST.. Good luck, but I am betting you'll come up with a load quicker than you'll think.
 
Dr. Mike, thank you so much, great info and I have printed it out and will give to my husband. Thank you!

Jim, I didnt know that about Nosler/180 pt/300H&H -how much history is that a 1948 bullet and a 1950 gun-cool

Thanks guys, for a minute I was thinking Aleena, Tom, Charlie and my grandfather were the only three people that liked, had and still used the old H & H

In looking through my notes today, I see that Aleena prefers the 200 also, but admits in her case she prefers more to less, and I quote --" just because I am hunting a hoofed animal, does not mean that another animal like a lion or brown bear might not appear and be aggressive enough that I will have no choice but to shot it" she also stated that--- I prefer to find one load and bullet that works perfectly in the rifle I am using and if I want something larger or smaller ( bullet wise ) I will use a different rifle with a load appropriate for that rifle and the game being hunted." To be honest I think this is exactly where my grandfather is coming from, but him and Aleena have more rifles than I do. The only reason I bring this up is I know she uses the 300 H & H all over the world --successfully.

Charlie, why did you sell your 300 H & H and what did you replace it with ? And again thanks for your load information, I have given it to my husband. As always charlie I hope your feeling better as I saw you visited the hospital again. Stay out of that place Charlie!
 
I just ran a few numbers on Hornady's ballistics calculator.

NPT, 180gr, BC of 0.474, mv = 3015fps (what my gun produces), 200 yard zero.

Drop at 500 yards = 38.1"
KE at 500 yards = 1751ft/lbs

NPT, 200gr, BC of 0.481, mv = 2900fps (numbers used here)

Drop at 500 yards = 41.4"
KE at 500 yards = 1618ft/lbs.

I'm not sure I "left anything on the table" by going with a 180, lol.

Now, let's be clear.... I did NOT post this to say my way is right and the others are wrong. Not in the LEAST.

I guess my point is......I have, at times, got myself twisted up in knots trying to get every last unit of measure of performance from something, and never stopped to ask myself "why am I doing this?".

In the case of my load selection for the H&H, it's easy....that's what worked, and I wanted to go hunting, so that's what I had shooting well, and that's what I took.

As I look at what that load brings to the table, though, I see precious little reason to go looking any further for anything else.

Now, this is my experience in one rifle. M70's are fickle beasts, and Lord knows that what one likes, another very likely will NOT like. So all bets are off when developing a load for another rifle. And some folks a whole lot smarter than I are advocating for a 200gr bullet. I will not even pretend to say I know better.

I'm just not sure I understand where a 180 loses out in this comparison. :)

Tom, your numbers are correct, but the problem is, that Litz's lists the 200 PT a little higher on BC and the 180 PT is quite alot lower, BC speaking, so it actually evens out and surpasses a 180. You are right though, you aren't leaving a thing on the table with your current load, but sometimes the advertised numbers are a little hard to get your head wrapped around. Again, I know Bill has run a 180 PT longer than I have been alive and has ALOT of elk steak in his freezer because of a 180 PT running at 3000FPS.

If your only shooting to 500 yards, I don't think anyone would ever notice the difference. I do think the 200 PT, up close and personal, would make me feel a little better about something that could harm me.
 
There is a lot to be said for mass when looking for the projectile that will provide lethality.
 
Tom, Scotty,

do you guys remember Bill ( Triple A ). I know he has passed away now, but he was a strong advocate of the 200 gr for the 300 H & H, as is Aleena, my grandfather, and Dr Mike, but I also know that Bill ( triple a bill ), aleena and my grandfather are all ( or were ) talking about hunting at UNDER 200 yards

however my husband latched onto Toms recipe immediately as he wants to see if it will work in my new rifle for shots over 300 yards and I like the nostalgia Jim mentioned with the 180 PT. But for up close and personal I cant argue with Scotty, Aleena, Triple a Bill, or Dr Mike. We know for a fact the 200 gr Swift works great but are interested in what the 180 will do and my husband is working on Toms load as we speak. But we have printed out what Dr Mike gave us earlier today because as in the long run, we want options for the 200 gr and Dr mike gave them to us

If Toms recipe with the 180 dont work, we will sue Tom---just joking as you know Tom
 
The advantage of the 200 will overtake the 180 eventually. Mike nailed it, while the 200 shows a difference of energy at 500, it is right at 500 yards, the 200 PT takes over and maintains more energy from there on out. Again, they are so close out to 500, there isn't anything worth sweating over Cheyenne, but the 200 is very impressive up close, maintains alot of weight and penetrates very deeply.

The 200 grain PT went 7 jugs, which is very impressive. This was at 25 yards. It maintains alot of weight as well.

Just an FYI. This calculation is with the 180 grain PT. Consequently, in this larger capacity cases, N570 is becoming one of my favourite powders.

Cheyenne,

You can't get blood from a stone! ;)

On a serious note, though, tell your husband it's best he works up to that load. As the QuickLoad data bears out, I'm right up near the top there, and while it's safe in my rifle, I don't think I'd jump right to that load in another 300H&H. I'd want to work up to it and see what the results tell me.

My velocities are pretty much right there with what QL suggestions. Looks like RL25 will spit 'em out even faster, to be honest, but man, I can't really see the need.

I'm sure Scotty is correct that past 500 yards is where the 200's will start to "overtake" the 180's. I know for me, that's not realistic for shooting. I can't practice that long, and I cannot conceive of a situation in my current hunting where I will shoot that long. 300 is doable, maybe 400 in a very specific situation, but 500 just isn't gonna happen, and beyond sure isn't doable. Heck, most places around here, a 600 yard shot would cross multiple properties! :shock:

For my purposes, a 400 yard limit is about right. Not sure what kind of distance you're facing on your shots. Some of the game you listed, I imagine, could be likely to produce longer shooting opportunities.

Scotty, I reran the ballistics calculator again, stretching to 800 yards.

The 180 wins on trajectory (-149" vs -160-ish", from a 200 yard zero), the 200 wins on KE (1067ft/lbs vs 1049ft/lbs).

The BC numbers for the bullets come from Nosler's website.
 
Dr. Mike, Scotty, Tom

THANK YOU

you guys are to kind and it is appreciated, what a ton of valuable information--thank you

and thanks to everyone who has responded as well

I have to get to work so I will check in again tomorrow. I am always curious as how you guys can keep up with so many threads and topics. I barely have time to check Rifles, hunting and reloading and I am back to work or outside playing in the wilderness

Tom, thanks for the caution. I will tell him but he is cautious to a fault, he sometimes drives me nuts.
 
I totally realize that Tom. My point was energy and wind deflection as well. I know most aren't concerned with longer that 300-400 yards so my point is mute, but I tend to look at what they do further out. For you, that 180 PT is about as awesome as you could want.

Good luck with the load work Cheyenne. I'm looking forward to hearing about the 300 and how it performs. Can't wait to start work with the 300 again.
