I've been trying to shoot sub inch groups at 100 yds for years. Close but no cigar until I got this .30 Cal FX Boss. It will shoot sub inch 100 yd groups consistently on calm days. I've just recently shot a sub inch with my .25 Royale, but it took many many tries. Not near as consistent as the .30.
I don't know if I have an exceptional Boss, or if .30 cal is really that much better? But if I come across another .30 cal anything that can hang with this Boss, I'm just gonna skip .25 cal guns all together!
I have a couple of .22 cal guns that are lasers at 50 yds, so I'll stick with my .22's and .177's inside 50yds and go .30 cal beyond that!
All that being said go with the Dirty Thirty!!!! The accuracy and the grin on your face when you shoot killer groups is worth the cost! Took me over 5 years to move up to .30 cal. Now, I'm like what took me so long?
