.300 RUM range report

[Guy Miner]

Took a couple of hunting rifles to the range with me today, including my brand spanking new .300 RUM, a Remington 700 CDL with a 3.5-10x Leupold.

Ammo was factory loaded Remington, with the 200 grain Nosler Partition.

I hadn't shot the .300 RUM, and anticipated prodigious, painful recoil. Not.

I think the nice stock design of the CDL, coupled with the very cushy recoil pad makes the big RUM a real pussycat to shoot! I had the rifle on a bipod, with a rear bag, and was shooting off a concrete pad at 100 yards.

Also, the power is there! The 700 CDL has a 26" sporter weight barrel. This 200 grain ammo chronographed at an average of 3190 fps! A couple of the shots topped 3200 fps. I can live with a factory sporter that hurls a 200 grain Nosler Partition at 3200 fps... :grin:

I didn't have much chance to assess accuracy. It seems good. It took three shots to get on target, then I fired a three-shot group. The group measures just under an inch - which I didn't think was bad at all for a powerful sporter rifle, fired from the bipod and still being broken in.

The only bad news was that the infamous Remington extractor broke on the 6th shot. Phooey. I've been shooting Remington 700's for 32 years, and finally one of the darned things broke.

At any rate, I'm impressed with the rifle and the ammo. Except that the rifle is broken. I'll get it fixed and then hunt like crazy with this beast - it's nothing but a big pussycat!

Regards, Guy :grin:

Congratulations on your 300 RUM, great round for just about any game. The 200 gr PT @3200 fps is a hammer.
I have a 338 RUM M700 LSS. It is my favorite hammer!
Yea, the recoil is there, just not as bad as most will tell you it is.

That is the only thing you gotta "worry" about. Other than that you're in!. If you do not reload buy 10 boxes from the SAME LOT and be done! (Remington has a tendency to change their loads in their factory stuff.)
Kinda hard at this point not to show off my SAKO 75 300 ULTRA :grin: :lol: :lol: :lol: :lol:

200 grain AccuBond
3175 fps
95 gr Retumbo
.292" at 100 yards
Below is a group at 300 yards
.675" at 300 yds.

Guess I need a digital camera!!! I'm shooting one the new RUM's, their new 700 XCR in 375. What a behemoth! But, the recoil is very managable because of thet "cushy" recoil pad.

I mounted a Leupold FXII 6x36, and with sling and 3 rounds on the scale it comes in exactly at 8 pounds. Easy to carry,

260 AccuBond being pushed with 94 gr. of H4350 gave me groups just under 1" at 300 yards.

Awesome! Sounds like you gotta good one!

Yup you need a DC!

Nice shooting Pop! I am a handloader, but I like to toss some factory ammo through my rifles first to sort of set a benchmark in both velocity and accuracy to measure my handloads against. Nice to see what the rifle will do with good factory ammo first. Agree about Remington changing their ammo lineup. I like this 200 grain Partition ammo that I found at a local store, but I don't see it in their current catalog. May have to go pick up another box. A 200 grain Partition at 3200 fps is serious medicine!

On the other hand, I have the loading dies and a box of 200 gr Nosler partitions on the loading bench right now! Some Retumbo on the shelf below...

Tric, I seriously considered a fixed 6x Leupold for this rifle. I've got a couple of hunting rifles and a target rifle with fixed power Leupolds, and have nothing but respect for those scopes. Went with a 3.5-10x for the .300 RUM - I think the fixed 6x would still be a viable choice though...

At any rate - I sure am pleased with the rifle - nowhere near as bad to shoot as I'd anticipated. Now, I just need to solve the extractor problem!

Regards, Guy

I had been hand loading for over 30 years when I bought a Browning Stainless Stalker in 300RUM a couple years ago. I spent six months trying to get an exceptable load. Tried many propellents, primers and uncountable bullets and loads. My conclusion is that the 300RUM is much more finicky than is any other high powered cartridge for which I have loaded. The best loads that I found were only pushing the bullet at an MV of 2900 fps, which is whimpy MV and negates any reason for have a 300RUM. I had acquired the 26" barrel 300RUM only with the idea of extending my range, after taking an elk at 304 yards with my trusty 30-06, which groups four rounds inside 1 1/2" at 200 yds. The best I got with the 300RUM was two inch groups at 100 yards and always a flyer in four rounds. The 180gr Swift Scirocco groups were as good as I could get. With groups like that, I'd likely miss a bull's vitals out beyond 300 yards anyway.
Has anyone else had similar experience with the 300RUM?

Roy,

My buddy had a M700AWR in 300 RUM that would shoot Remington Factory 180 gr and 200 gr PT's under 1 inch. We were going to start a reloading project but it was stolen in a home burgerly. He replaced it
with a 300 Win Mag.
The RUM's are very capable of excellent accuracy. My understanding
of the 300 RUM is you have to use the right powder. H1000, RL25 and Rutumbo seem to do the trick for the 300 RUM.

I did use RL25 and Retumbo, along with a number of other propellants. Granted, my story is anecdotal, as I only worked with one rifle. When I returned the rifle, Browning told me that they could find nothing wrong with it. Several people on another discussion list told me that the 300RUM was not for me, because I expected too much, too quickly. This, after 900 rounds, fired at the range. Perhaps they were correct in saying that the 300RUM was not for me. The rifle went down the road. Between 30-06 and 7mmRemMag, I figure that I can take any game that I am likely to go after. The slight advantage of higher MV made no sense to me, after I really got into the 300RUM cartridge.
