Re: .25-06 & .57wtby

Crap, 3400 isn't THAT high for a 25 -06 with a 26" pipe using 115's if the powder is correct; most books are 22-24" barrels with that round. I've seen 3100-3200fps with my 25 wssm with speer 120's, but settled on a start load of 4350 at 2900 fps. Incidently, that start load is only supposed to do about 2750 fps. My 25 wssm is a 24" coyote. Some barrels are just a bit fast, and vice versa.
With a 22" 25-06 you will have a time breaking 3300 fps with a 100 though at normal pressures.

72.5 gr of re 22 yields 3800 from a 100 ttsx. The .06 can't touch that

Re: .25-06 & .57wtby

heres what quick load says about the pressure need to do this in a 25-06 with a 115 bt in a 26 inch barrel using re17. NOT IN MY GUN!

A 94% case capacity load of 54.5 gr. of Reloader-17 calculates to 3,400 f.p.s. with an estimated peak pressure of 79,290 p.s.i.

A 84% case capacity load of 48.9.0 gr. of Reloader-17 calculates to 3,117 f.p.s. with an estimated nominal recommended maximum pressure of 56,971 p.s.i.

Hotter pressure than I figured; I'd figured high 60's. Too dang hot then...... blow your face off pressures, even if he has a "fast barrel" on his 25-06.

Actually, my load is 55 gr, I went as far as 55.5 with a slightly sticky bolt and backed off a 1/2 gr. I am getting slightly flattened primers and no other pressure signs. Also tested 110 AB's and got 3500 fps with them with 55.5 gr. The 115 BST's were a little more accurate so I went with them.

Hey fella's, we're all big boys. These forums are about sharing info and I've learened a lot here and shared a little of my experience as well. You are free to take it or leave it. I am an experienced reloader. I know what max and over max loads are - been there done that. I posted my 25-06/RL 17 results a couple of years ago and of course there were some skeptics, but there were a few who went out and worked up some loads themselves with excellent results and thanked me for my info.

Cheers and good shooting,

Mark

I would still be a bit concerned. I had a pressure gauge on my last 7stw and the bolt lift wasn't bad at 75K psi. It took more than that to make it stiff. You've got a longer barrel on your 25-06, so another 100 fps may be in order without issues, but you are over 200 fps hot. Over 65Kpsi just beats everything up to much to stay there.

As far as sharing info and we're all big boys, lloyd and I seem to care more about your well being than you do. I'm just stating what I've seen and lloyd is giving you the info he has. Take it or leave it; it's your choice as you've said.

I appreciate your concern but I am VERY comfortable with this load in this rifle. Let's consider some facts about reloading. There are many factors that affect pressure and velocity, including brass, primers, chamber, bore spec, powder, bullets, etc. Certain combinations will give you higher velocity to pressure ratios. I.e., in my 25-06 I found about 50 fps difference in using WW brass vs Rem for equivalent pressure signs. Like a lot of other reloaders, I don't have a pressure gauge and I go by what I see and feel.

I have seen some big differences in max loads and velocities in different reloading manuals for the very same cartridge, bullet and powder combinations. I have had several shooters in this forum message me for load details and I always encourage them to start low and work up carefully.

I have shot many rounds of this load out of this rifle without what I consider to be excessive pressure signs.
