BARREL LENGTH FOR 6MM CREEDMOOR

[6.5guy]

I’m About to build a 6mm creedmoor on a terminus Zeus action for a mid prs/coyote gun gonna run it in a krg bravo stock for coyote hunting to keep it light as possible and a mpa chassis for prs I was thanking about going with a 20 or 22in barrel for the coyote barrel and I was wandering wat kinda muzzle velocity I would b getting out of those and witch do u guys recommend 20 or 22 The reason I’m going so short is because I will b running a CAN also I’m gonna run factory ammo at first for the coyote barrel wat freebore do most guys run for best preformance I will b reloading after first 5 boxes of factory ammo and also wat freebore do u recommend for the prs barrel reloads only in it preferably unless factory shoots so good I don’t wanna reload witch is doubtful but who knows any info will help guys thanks a lot

I run 28" barrels and get about 3000fps from factory 108 ELDs. So 20-22" I would bet you would be down in the low 2800s with those. Factry stuff shoots pretty good. i shoot it in matches. It's plenty accurate for that but if you wanted to reload you can save a little money.

As for freebore, if you plan to shoot the factory 108s then get the .183 SAAMI freebore. The factory ammo is about .020" off the lands with that freebore. With a shorter freebore you will be jamming factory ammo into the lands. Figure out what bullet you plan to use most and work around that.
