Re: Barrel Twist 7mm Wby

Very interesting post as I planned on having a 270Wby build but gunsmith is talking me into a 7Wby. I've got to get some cases and make up dummy rounds then we will decide on barrel twist /rifling good thing my gunsmith live close by and he has a good 600yd range at his place.

Most places I hunt elk 600/700yds be a long shot I've got plenty of rifles to handle my hunting needs but can always use another one. I just had a 257Wby build used a 25" long Shilen 1/9 twist barrel no Wby freebore case was headspace on the shoulders barrel marked and it a pretty nice shooting rifle. I don't have a standard factory chamber 257Wby rifle to compare loads with etc but I'm using less powder getting better than velocity published.

I'm thinking 3000fps with 175gr bullets in the 7Wby in a 25"/26" barrel. I've read that article posted on 6BR about that 284 with 180gr Bergers @ 2900fps appr out of a 30" barrel.

Well good luck on your project and keep us posted.
