1. Dave shoots a M38 better than a G26, Earl shoots a G26 better than an M38. Adam can't hit the broadside of a barn with either. Steve hits all tens with both. So..... Dave should CCW the 38, Earl the 26, Steve should buy the one he likes most and Adam should pal around with Dave, Earl or David. Carl should try 'em all and decide for himself rather than watching youboob.
2. Cartridges should be roll crimped (especially if fired in revolvers) the crimp provides a gentle brake when the powder is ignited allowing for a consistent pressure to be reached before the bullet begins its journey down the barrel. If you have ever used a single stage reloading press you would have noticed the inconsistent amount of pressure required to seat bullets. If you have taper crimped ammunition you would also note the inconsistent amounts of pressure required on your lever to complete each round. A roll crimp into a groove or over the end of a wadcutter simply provides a consistent start. Obviously you cant roll crimp ammo you feed to any firearm that headspaces on the case mouth. But feeding taper or uncrimped ammo to a revolver (especially a light revolver, in a load with brisk recoil) is an invitation to an ammunition caused malfunction.
