Yup, if it does change anything, which is doubtful. You don't really think that much gas gets by the plastic wad just because the forcing cone is ground out do you?
Probably not. But, in my case, it was nice to remove spent ammunition from the gun that didn't have the end ripped off. Spent plastic cartridges, with the ends ripped off, are somewhat un-appealing to me.
I have no idea if recoil changed, or velocity went up or down. But, patterns are much improved at the yardage I put the gun to use at, and instead of playing with a reloader, I just bought a bunch of English ammunition that fit the bill. Actually, I did that first, thinking it fit the bill, and discovered ripped ends on spent cartridges.
The gun doesn't do that anymore. I'm going to guess that is a good thing.
Best,
Ted
