Group Buy barrels any good?

[Constitutionalist]

Took my 20" gbb out this weekend. Shooting 90g varmmaggedon with H335 and cci 450 and it was great!! 5 shot groups @100y average 3/4"-7/8" and that's with a 10-20mph winds gusting all over the place. I havent tried any other bullets as this is a dedicated coyote gun so no need to explore other bullets.

Sbowhunter,

Mind if I ask your charge and overall cartridge length? I just picked up some of 90gr Varm's and plan to start working up a load.

Thanks!

John
