Re: What Cal?

Been doing a lil research on the 6.5 gibbs, it has I think 8-9 grains gain of powder capacity over the parent case. Have read that with a good barrel 28" long will duplicate 264 WM 24" performance with better barrel life, I may let you know, got a 270 win settin in the safe not doing nothin.

Re: What Cal?

Skip with a 7mm burning 70 od grains of powder that going to be the 7mmRem mag size. Like Kirby said when you move up in bullet weight and velocity the recoil also gues up ad the barrel life gets shorter. The 280Ai with a good 26"will duplicate 7mmRem mag factory ammo when shooting bullet up to 150 grs once the bullets get heavier the barrel either has to get longer or the case bigger. Also the choice of varmint bullets goes away prett quick.
if it were me personaly , I'd probably go back with the
25-06 wight a fast twist and shoot he heavy for caliber Wildcat bullets for long range and the lighter varmint bullets for the short stuff. But if your looking for a good "deer" rifle and the smaller stuff is not gonna be shot at as much then the bigger 280 would be good choice.

You mentioned that you diden't want to burn a pan of powder to shoot a 308 , well my 308 burns less powder than your
25-06. The 308Winchester is a good LR caliber thats often overlooked due to the new mags but it'll get out their and print groups at 1000 yds with the big mags it just takes a little more dope work on your part. Seeing that you have a long action you could use 190-220 gr bullets and seat then way out and these high BC will cary good accuracy way out.
If I'm not mistaken a guy that shoots with Kreg Slack uses a 308Ai and 240gr bullets to shoot out to 2 MILES !!
I think thtas a hell of a strech for the little case but they do it

Re: What Cal?

If I was going to go .308 I would get the bolt face opened up and get a .300 WSM that will be able to seat the 200 and 220gn bullets out far enough so that the case capacity is not reduced like in my .300 WSM A-Bolt [img]/ubbthreads/images/graemlins/shocked.gif[/img] I like the sound of that.

Can someone provide some data on the .280 AI (standard bullets) and .25-06 AI (shooting the wildcat bullets)?

cheers

nosler 280 AI, 24", 1-9", Fed.210;

MAX. LOADS!!!

140gr.-
IMR 4350... 57.5gr. 3134fps
IMR 4831... 58.5gr. 3164fps Most accurate.
RL19... 60.0gr. 3146fps
VN160... 60.0gr. 3152fps
RL22... 63.0gr. 3196fps

150gr.-
IMR4350... 56.5gr. 3014fps
H4831sc... 60.5gr. 2994fps Most accurate
RL22... 61.5gr. 3095fps
VN165... 63.0gr. 3055fps
IMR7828 63.0gr. 3107fps

160gr.-
IMR4350... 55.0gr. 2901fps
H4831sc... 56.0gr. 2855fps
RL22... 58.5gr. 2929fps
IMR7828... 60.0gr. 2962fps
VN165... 61.0gr. 2963fps

175gr.-
IMR4350... 51.0gr. 2719fps
H4831sc... 54.0gr. 2707fps
VN165... 57.0gr. 2748fps
RL22... 56.5gr. 2808fps
IMR7828... 58.5gr. 2828fps most accurate

Hope this helps, compares balistically identical to the 7mm Rem short mag. An excellent caliber, I'm more partial to the 6.5mm bore than the 7mm IMO... 6.5-06AI?? Got some 6.5-06 data if you're interested (NOT A.I.), all from Nosler Fifth Edition.

Re: What Cal?

They seem like a good performer.

Any data on the .25 with wildcats?

cheers
