Looking at Creeker's post the other day inspired me to try the 45 ACP cyl that came with my gun years ago. Went out to the range today and not a single round would fully seat in any chamber - bummer. Shot other guns tho. To make a long story short, I discovered that no sized case (no bullet involved) longer than .889" would seat in the chambers. According to Hornady, .898" is the spec length for 45 ACP cases and the cases I measured were more like .891-.898 and would not fully seat. So, I watched Lynn shoot his 45 ACP cyl so I know his works, how about others ? BTW, even some factory jacketed ammo would not fully seat.
