good in wind


Hi to all as this is my second post.
I have a rem 700 in 7mm stw.When I wear the barrel out I want to try a different calibre.
I am looking for something that will give me less than 9 inchs of wind drift in a 10 mph wind at 500 yards.
What suggestions have you guys got?
I would prefer the rifle to weigh 12 pound or less & not kick too much.

Regards
hjl

Re: good in wind

What elevation are shooting at? What caliber(s) are you considering?

Most of the heavier bullets pushed fast in each caliber from long barrels will do this, but will be more likely to do it at elevations well above sea level. Add a brake to reduce felt recoil in the big overbore chamberings.

Working with your current 7STW - Shooting the 162gr A-Max @ 3,200 ft/sec you should have about 9" of windage @ 450yds in a 10mph cross wind.

Close enough?? [img]/ubbthreads/images/graemlins/wink.gif[/img]

Dear varmit hunter,
Thank you for your reply.According to Sierra Infinity a 162 amax @ 3400 has 10.9 inchs of drift at 500 yards. I am using 162 amaxs at the moment.I have been slack & haven't chroned them yet. In my new caliber I hope to have less than 8 inchs of drift if this possible.
Regards

Re: good in wind

Hi, At 660ft. elevation and those "smaller" calibers and the chamberings you mentioned, I think that you are going to have to be going near the extreme end of long barrels and high velocities with heavy bullets, and it still may not be possible with those chamberings. Without knowing which bullets you plan on shooting (it'll have to be very high BC wildcats, I think, pushed very fast), it's difficult to do the math on the ballistics programs. There's alot of guys on this board that know much more about this than I, but I would take a look at Fiftydriver's new chamberings (do a search or two for the Allen Mags) in those calibers as a good bet...but at that elevation it may be a challenge even with those. I don't know. Good luck. I think you may have an easier time doing what you want in the .308 caliber.

Re: good in wind

I would build a custom 7mm STW and be done with it. You should be able to shoot 162 A-max's at 3300fps or 3400fps with a 28inch or more barrel. Get one with a 8 twist and you could shoot the big 200 Wildcat around 3000fps or a Berger 180 around 3200fps. The 7mm's really shine in wind drift and drop pretty tough to beat them.
