Re: 6.5 stw

I've got a very high quality 30" heavy taper 6.5 barrel in 8 twist myself and have considered chambering it in the stw class case just as you - I'm also having difficulty finding any useful info - A customer of mine did a .264 Thor awhile back which is a stw 35 degree improved, but he did it in a 26" barrel which I thought might have limited it's performance - If you do a search out here in internet land on ".264 Thor" you will find a few bits of info, but still not very much - I personally feel that if you don't use at least a 30" tube you're not gaining anything - Considering the excellent BC's of the 6.5 bullets, surely somebody out there somewhere has done an extreme velocity .264 project and can provide much more useful info - JP

Re: 6.5 stw

Myself and a few others are burning up barrels with a 6.5 WSM. That's kinda the way I would lean to get away from a belted case. 6.5 WSSM, 6.5-284 or the WSM will get the job done.
For what it's worth- H1000 64grs, 141 gr Cauterucio at 3150 fps in a 26" tube. Biggest 5 shot group is 0.257" at 100 yds.

Re: 6.5 stw

from what I have found with several calibers including the 6.5 , the realy high BC bullets don't realy like to be pushed much faster than 3000-3200fps or the accuracy suffers , at least with the Berger and Hornady A-max bullets.
Why shoot 80+ gr of powder to get a lesser result than with 65gr ?

Personaly I'd rather give up a 200fps if it closed my groups by 25% , I think a slow hit is better than a fast miss as long as you slow hit has enough thump to offer a quick kill.
Thats why if it came to making a life of death shot at 800yds I'd be shooting my 308 rather than any of my other 30 mags.

Re: 6.5 stw

thanks for the info guys, if i go with the stw if will not really be for any shots over 500 yrds, i just was thinking more along the line of a real deer thumper. i have a 264 win mag now and it sure does a number on deer i guess i figured more speed would do even better, as i don't like to chase deer after i shoot one. maybe just another 264 wm anyway thanks

Re: 6.5 stw

I built a 6.5 STW and have some load data from Layne Simpson. With a 26" barrel and a 100 grain Nosler B. Tip moving 3850 fps. I am having Christensen Arms build me one with a 28" barrel and hoping to improve this a little. The average goes:
100 grain bullets - 3850 to 3950 fps
120/125 grain bullets - 3500 to 3600 fps
140 grain bullets - 3400 fps

This is all from my data and Layne Simpson's. Email me for questions. This is a definite fast mover and super accurate.

Re: 6.5 stw

doc136,

If you don't mind me asking, what kind of consistant accuracy are you getting at those velocities?

Thanks for your time!
