25 cal 134 Eld-M vs 133 Berger EH

[jjohnsonElknewbie]

This is totally doable, in lapua brass I never found pressure with 131s and rl26 till around 3100mv from a 25in barrel

Rl26 will add 150+fps over H4350.

Agree, and I believe @willfrye027 gets 2900+ without pushing pressure with the 134 ELDM in a 26" CM.

Previous barrel was 26”, n555 pushing the 135s 2930fps with lapua brass. Some pieces are up to 10 firings without a lost primer pocket.

Current barrel with 134s is 26” with h4350 doing 2850ish in alpha brass. Can be pushed a little faster than that but was getting an occasional heavy bolt with long strings in hot weather so I toned it down a little.

Thank you and if a guy has some unobtainium RL-26, 3,000 is likely pretty reasonable in a 26".

You can probably do it with normal powders and be over pressure. The 131s IIRC have a shorter bearing surface and can be pushed a little faster than the 135/134s

I have a tikka w/ a 24in brux 25cm, lapua brass, 134eldm, H4350, anything over 2850 is pretty damn spicy. Tikkas don't handle psi as well as other actions, and in my opinion, brux barrels are tight, at least the 3 I've had would get into psi fair bit sooner than expected.

Not all barrels are the same!

How long is your barrel?

It’s a 25” barrel

I have been toying with the idea of ordering a 25 saw that is advertised to get 100fps over 25cm.

Would it be fair to expect 3000fps from a 20" 25 saw with r26 safely and reliably?
Alpha brass

A 25prc struggles for 3000fps from that short a barrel. The saw will be really hot to do it.

You will not get 3,000mv in a 20" barrel with a 25 saw. I'm running 54.5gr of H1000 in Lapua brass in my 22" 25-284 (66-68gr capacity). That load and 134 ELDM is getting 2,828 MV.

The SAW case has 54.2gr of total capacity (not usable) and runs about 75fps faster than the 25cm according to this article from WTO.

If you want 3,000 from a 20", you're going to need a serious magnum cartridge- 25 WSM, 25-7PRC, 257 WBY, 25 Nosler, etc...

25-6.5 PRC and 25 SAUM only have a slight capacity advantage over the 25-284, and will not get you there either.

I have 18" & 20" 25/6.5prc's so im familiar with those velocities.

Berger lists 25cm 26" 135g r26 max @2944fps

I agree with all

Agree with 99% of this!

My 23in 25prc is running 59.4 H1000 with a 134 eldm at 3050mv. PSI was 60.2gr, 3120mv. Rl26 will give you another 75-100fps observant pressure.

I had a 26in 25saum when the 131 came out. I believe 59gr rl26 was going near 3300. So yeah I personally think the 73-74gr capacity saum has the ass to make 3k. I've shot a lot of saums and prcs, even tho the saum only has 5+- grain capacity advantage, it always seems to have a top side of + 60-80fps. Maybe it's just been my differences of barrels, but that's been my observations.
