I've got a BPS upland 22" invector barrel.
With a Comp-n-choke with Rem nitro #5, I got .8 pellet per inch coverage.
With Carson flush turkey choke with Prairie Storm #6, I got .7 pellet per inch coverage.
I'm not into expensive chokes and high dollar ammo, so both of these were
good for me at 30yds. Hope this helps.
For HIS service,
R.D.
