Short barrel 338 RUM
- Thread starter jwhunter
- Start date
Mines a bit longer at 23". I've shot the 200 gr Apex Afterburner at 3200 fps with R26. The 210 Hammer HHT at 3160 FPS with H4350. I could probably go a bit higher, but both shoot good there with no pressure signs. I went with a lighter weight copper bullet because of the short barrel. Depending on how far you want to shoot, the afterburner has a decent BC.

dumb question, but I have always wondered about the physics behind a brake inside a can.
Does a brake inside a can reduce recoil better than a direct thread?
I was talking about their new rr break. On the end of the can. A break inside the can will help protect the can by seeing less pressure. Based on my experience blowing up 2 silencerco cans. but I doubt it does anything for recoil. Maybe I'm wrong.

If I wanted a short barrelled 338, it would be a 338-06. I see little point in trying to burn 100 grains of powder in a 20" barrel and process all that gas through a brake just to get the recoil into a manageable range. The muzzle flash would be tremendous too. We can't use suppressors here, but I would think that less gas volume would be better for a suppressor too.

The 338 RUM is a beast in a good way. FPS gain with a 29" barrel will be close to a 338 Edge with a 26". No experience with a 20" RUM but a 338 Federal loses 100-115 fps going from 24" down to 20", that's with the small 308/243 parent case.
A 338 WinMag with a 22" running 225's would be a consideration imho.

My 338 RUM is 10 lbs and recoil is not an issue with the 5 port TiPro brake. It's my first 338 and I've enjoyed it so much I'm going to build a 338 RPM this spring.

Hello jwhunter.
I have been running a 22" Broughton barrel 338 RUM Ruger Hawkeye for several years now. Current load is: 250 grain Bulldozer 2, 99 grain H1000, ADG brass, & F215M, with a OAL of 3.745. It runs at 3046 fps with single digit ES and right at 1/2" @ 100 yards. During load testing, it was ran up to 101 grains of H1000 with no pressure signs. This load has worked very well for hunting.
Although you didn't ask, a 285 grain ELD-M load was powder ladder tested and showed great accuracy with 3 loads @ 92 grains of H1000 plus or minus 1 grain grouping at .176" @ 100 yards. They were 3.740" OAL and ran 2758 to 2820 fps with no pressure signs.
The rig's weight is around 10 pounds depending if the bipod is on or not. The 338 RUM does produce a bit of recoil, keeping the scope from sliding took a little work. Then, the 3 port side baffle brake was not enough to keep muzzle rise down if a hard secure hold was not used. It wears a 4 port side baffle brake now, which puts the overall barrel length to 24".

How's the performance of those bulldozers @bridgerbear

Hello grouse,
I sure like them.
They are very predictable with my Shooter app and did not have to correct the BC provided. Did some cross canyon rock shooting just shy of 1000 yards over in the Elkhorns to test out.
As for game, they so far have been pass throughs on everything. The exit holes at smallest are baseball sized and the largest are softball sized. Most have been high lung, below spine, ribs only for bone. A couple went through shoulders and one through backbone; Broke the far shoulders and cut the spine in half. Distances have been from 42 yards to 807 yards. A few DRT, broken bones all went right down, and high lungs some ran a little bit and some went down.
As far as reloading, had a some trouble with Redding seating stems and the BDBL2 kept getting firmly stuck in them. Several conversations with Redding and several different of their stems, plus buying a higher end Redding die set, did not solve the problem. Neither did trying to dremel the shape into the stem. Then, gave a RCBS Matchmaster 338 Lapua seating die a try. The Matchmaster worked extremely well, no stuck bullets and runout is usually is .001-.003". Never had to play with seating depth either.
I sure hope someone gets them back into production.
Cheers
