If your adverse to spendy... dont bother getting into shooting.the only way to get better is to shoot/practice... That takes ammo. Most guys roll their own.
Ipsc doesnt mix platforms. . You're either shooting a pistol, rifle, PCC or shotgun... and within some of those there are "divisions" and power factor to consider...
You really need to read the rules to get it straight....
That vid was of a USPSA style "outlaw" match...
I wouldnt recommend any of the guns you mentioned...
Fair enough. Was just looking at alternatives to the AR platform. Spendy is relative, paying double for ammo is still double though. I’ll start reloading when I get a .357 revolver as 9mm is tolerable right now.
