We need a new Caliber for the new powerful rifles.

[Airgunmann]

7 mm would be all right with me

I dont think anybody is missing anything here... the whole point of the thread (or so I thought) was to discuss possibilities of calibers with these new guns. Nobody is saying "let's throw a 140gr ELD match in a .264 airgun" here. 50-100gr though? Heck yes. Upgraded .22 M3s are already pushing subsonic .22lr numbers. I wouldn't doubt for a second that whatever FX releases as an M4 will improve upon that as is. I also wouldn't be suprised if the magazines were built to handle longer slugs either. If (and I mean if) they can manage something that can handle 3/4" ammo we are talking possibilities of 100gr .264 slugs. Personally I was thinking 50-60gr but if .257 can handle 80gr, why not go bigger? 150+fpe is far from out of the question with these newer guns...

90gr 257 is not accurate 100+ yards.. 85g is the proven max that that the 1-14 twist will stabilize..depending on the bullet profile..there is power to push up to 105g but not aviable twist rate.. that is why I paid for the 1-8 n 1-9 ... 1-10 was tested to since the beginning by Mr Bowman n Cedric.. and it was a no go ..been the 1-14 chosen as the best option.. up to 85g ..a 1-7 was tested for heavy bullets but it didn't work.. but the twist rate calculator puts 100g ..0.9375 length .. stability between 1-8 n 1-9 at a average speed of 1000fps ..if you look at the profile of the 257-418 - or the 257-100 there is a bit more to be said about 257 if we manage to stabilize better n heavy bullets... same thing also applies to the .224 with a condor ss frame n 33" barrel 65gr could easily be pushed at 1000fps..
