25 gibbs

[skeet]

I'd make ya trade on a 722 in 222 Rem Mag..LOL. The 257 is going to go. I have way too many 25 cal rifles...But it won't be a giveaway. You just don't see many B grade 721 & 722's. PM me an email and i will send a pic or two.

JP the Gibbs sounds real neat. . I thought about makin a 25-308 and also a 250AI. ...but at this stage of the game..will probably stick with what i have. Too many rifles and not enough time. After you get it going..run 'em over a chrono and let us know what you get out of it. I also really like the Number 1

Based on my 240 Laser the R-22 is about the best possibility as it takes a fairly slow powder to feed the Gibbs a diet it likes and R-22 is close to the burn rate of H-870. 4831 does not want to give top end velocity but 4350 works pretty well if you want to try it. Of course the best is H-870 or AA 8700 and both are no longer made.

I would try the Nosler Ballistic Tips as their jacket is as tough as nails and will stay put. The Berger VLDs are just as tough but a bit pricey. The Sierra bullets tend to shed jackets in the 257 and 243 when pushed hard. I could push a Sierra 100 to 3,700 with 4350 but the jacket would rip off, it also ripped jackets off at 3,600 about half the time. I was running a 1-7 twist to shoot the 105 Berger VLDs so it spun up those 6mm bullets pretty hard.

The Bergers would hold together at 3,800 fps.
