First 338/375R Range Report!!

[jmad_81]

No biggy scotty, we are sharing a brain on this. I might try them .1" off. I tried 3.838" and it got worse. I'll reload the 3.845"load and try again. Going to double check and make sure all my brass is trimmed the same and weight sort them for this next round.
I still have not played with the seating depth in the 84gr 7828 load much either. If neither of them shape up I'll move on to a different powder.

 

[SJB358]

I think your in the right spot Jake. I would be itching to try RL19, but I know it probably wouldn't peak out at 3000+ Probably be closer to a 2950 load. 19 has been so good in the 338 Win Mag, it seems like it has to work decent in the big Ruger case...

 

[jmad_81]

I'll get the Scotty. I'm starting with the slower burn rate powders and working my way down.

 

[IdahoCTD]

If you have it I'd try H-1000 too Jake. H-1000 and 7828 edge R-22 slightly in accuracy in my .338 Baer's. I'd load 4 grains more than the 7828 loads.

 

[jmad_81]

I might have to give it a try. I tried it with the 225 SST and was running out of room in the case. But, I'm shooting the 225 AB out a little farther, so it might be worth revisiting.

 

[IdahoCTD]

Both of my guns love 215 and 250gr Sierra's. They aren't ideal hunting bullets but they will sure kill stuff too.

 

[jmad_81]

I might have to look at some other bullets if I can't get the 225 AB to shoot how I want. Still have a lot of work to do with them as I get some basic load ranges built.

REALLY HOPING NOSLER COMES OUT WITH A 250 gr. .338" ABLR!!!!!

 

[SJB358]

Jake, that 250 AB would be pretty awesome as well!

 

[jmad_81]

I might have to try to find a box of them to play with next.

Can you get me a few QL predictions running them 3.560"? I'm betting that 2800-2850 would be the upper end. Should make one hell of an elk rifle!

 

[Oldtrader3]

I have a silly question, looking at the loads and velocities for the .338/375 it seems awfully close to those loads and velocities of a .340 Weatherby? Maybe just a little slower for the 225 grain bullet in the .338/375 but close enough that an elk would never know the difference. What is the difference in case capacity between these two cartridges?

I have a silly question, looking at the loads and velocities for the .338/375 it seems awfully close to those loads and velocities of a .340 Weatherby? Maybe just a little slower for the 225 grain bullet in the .338/375 but close enough that an elk would never know the difference. What is the difference in case capacity between these two cartridges?

Charlie, QL shows 1/2 a grain difference. The one reason I like the 338/375 is the ability to use a regular M70 action and getting the Hornady cases. The 375 Ruger cases are pretty tough. Either are just about identical though..

Yeah, I am not questioning the utility of the Wildcat but it just struck me with Deja Vu all over again, when I read the loads and velocities. I certainly understand the desire to use and .30-06 length action and a non-belted case. I did a ton of load development for the .340 Bee and although I did not use RL 22, I did use IMR 7828 SSC extensively. Okay, I am not losing my mind, not today anyhow.

Nope, your right on Charlie. I actually was going to build one myself, but my wife got me the Alaskan. With the 25" barrel it does everything I need it too. Still like the 338/375 and 340 alot, but I like my Alaskan more.

Scotty, I had two Alaskans, a .338 and a .300 H&H. I really liked both of them and did not buy the .340 until I sold them. I really regret selling those particular pre -64, Model 70's because I can not afford to replace tham now at today's prices. I hope that you enjoy yours as much as I did the ones that I owned.

I had wanted a .340 for a long time as well, even though I am still not a Weatherby Mark V fan. Having had one, I would rather not deal with the double radii and the belt. The .375 ruger case sounds like a fine platform for .340 perfomance without those features and in a shorter case.

Well, I got out a few time this last week.
This target was with RL-19 and some 225 AB. I didn't have a lot of it. I started with two grains above 338 WM book max and went up in one grain increments up to 79 gr. I loaded three of 76, 77, and one of 78, and 79. I didn't want to waist any powder just to deveople load data. 76 gr showed some promise, but the third one opened it up a bit, and I was only getting 2840. I woeked my way up, groups get worse and 79 gr was to hot.

The next target was mostly H1000. I did try to shoot 78 gr on RL-19 (left group), it didn't do so great. I started with 84 gr of H1000. It put two very close together and threy one out. 85 gr shot a nice triangle group in the 1-1.25" range. 86 shot two in pretty much the same hole, and one about .5"-.75" out. One thing I noticed with H1000, is the hotter the load got the smaller my extreme spread on my velocity got. I don't think that 86 is to hot, but I'm not sure if I'll have room to go up another grain or not. I might try it later. I have two more batches of 86 grains loaded up. Each is .005" shorter. Hopefully this brings the last little guy to the party.

If H1000 doesn't pan out, I'll try to get my hands on some H4831. I'm thinking that I might have to give the 250 AB a run in this as well. I have also been playing with the idea of trying some 250 VLDs, but I'm having one hell of an internal debate about that. They are not a traditional hunting bullet, but they are a pretty big piece of lead, and I'm not really screaming them out there so I would think that they would poke a hole or two in an elk/bear. If Nosler would hurry and drop a 225-250 ABLR the debate would be over. Playing with some rough numbers, a high BC 250 at 2800 (hoping to be in the 2850 range) has just under 2,000 ft/lbs at 800 yards. Pretty dang sweet out of a 9 lbs packing rifle.

That lowest group looks pretty darned good. Two touching and one a bit out, with a 225 gr AccuBond at 2900+ fps if I'm reading the target correctly.

"One thing I noticed with H1000, is the hotter the load got the smaller my extreme spread on my velocity got." This is not unusual in my experience, with the slower burning powders.

"I don't think that 86 is to hot, but I'm not sure if I'll have room to go up another grain or not."

Interesting, not having load data avail to you via manuals. No strain gauge info. Nada. Just some well educated estimates.

I think that with the load development you've done - you're already at the point of having a powerful, accurate, big game rifle that's more than adequate for ANYTHING in North America.

On the VLD... I like them on deer sized game. Have taken three mule deer with them at 175, 230 and 400 yards. Used the little 115 gr .257" Berger. Worked very well in each case! A couple of buddies have used the 210 gr .30 cal VLD on elk with excellent results. I would not expect the bone & muscle smashing performance achieved by a Partition or AccuBond, but they do work.

Congrats on taking this new rifle/cartridge so far already!

Thanks Guy, I'm really learing a lot.

Building my own data has made me slow down and think about things pretty hard. I'm paying more attention to bolt lift, primer shape, and how easy the next primer seats. There have been a few stuck cases as well (partly from a sizing issue and partly because of getting greedy). One thing about building a wild cat, making brass can be a PITA so I'm trying to make it last. Now that I have tempered my expectations about what this round will do, I think I should not lose any more brass. All in all, it has been pretty fun. I'm just glad that I didn't need it a month ago. Building load data takes a while.

I might have to play around with the VLD, I knew you liked them and was hoping to get your thoughts on them. Just one more thing to play around with I guess :lol:

 

[Oldtrader3]

I have had good luck with IMR 7828 SSC. I use it both in my 7mm Rem Mag and my .340 Weatherby (now sold). I works well and accurately in both.

Jake,

All your data is very interesting. I do believe the rifle is showing great promise in the accuracy department. As Guy has noted, a 225 grain projectile at 2900 fps is a fearsome load. Playing with seating depth may tighten the group to such an extent that your heart skips a beat.
