"I bet you wonder why noone pays attention to your posts"

Then why are you? Looks like you just lost your own bet.

Again, it really does not matter who reads my post, my life will continue on just fine.



RR says,
"but I'm not stupid"

Now that's a bet I'll take!

Re: Barrel length and powder burn rates?

you've made your case, how'd it work out, looks like all you've got left is to take a personal poke, help yourself, keep quoting the guys who write in the gunrags to make a buck, but go read somemore of his stuff, its mostly a smokescreen.

su37
I am in the process of have a rem. 260 built. i have a 26" barrel from brux
1-8 twist. what powder would you recommend best for this caliber my bullets will be 139 lapua and some 142 gr smk's
some people told me that h1000 should be to slow
h4831sc might be not produce the velocity that h4350 will.
i just want to know what will give me the best velocity.
i will have to shoot the load to find the best accuracy.

Re: Barrel length and powder burn rates?

I personally burn 50 grains of RL25 in a once fired Lapua 243 case necked up to 6.5.

I get 2,790 mv behind a 140 in a 22" barrel. Longer target bullets may vary.

Works for me.


RR, I think if you call up Chub Eastman who still hangs out at Nosler and Ken Howell
who wrote the book on ballistics. I believe you will find they agree with John Barsness.
Two of many.

I'm just a dumbclutz still trying to figure it all out.
