FINALLY found the magic combination for the Raptor .25, could never quite get it to shoot RMR/FX Hybrids well so I figured heck my Maverick VP sends them out at 1004fps so....WHY NOT? Cranked up the regulator a touch and only a touch and OH MY smaller than a dime at 25 yards at 1018fps , shoved in some 33.9 AEA's and they perked along at 939 and dime groups. The only reason the last one with the AEA's was 932 it was falling off of the regulator. Note to self, self...DO NOT MESS WITH THE GUN. Disclaimer, the first two shots in both strings were a touch higher then it settles down so I did cherry pick but still pretty darn awesome. And 60 Ft#'s with the slugs and 65ft#'s with pellets, at the muzzle.

How do they do once you stretch them out to 75, 100 and beyond? I’m a TJ barrel guy and the barrels they sell to the general public, at least for me don’t do well with a Hybrid.

Honestly, I don't know BUT...I'll find out on Wednesday. I had garbage in the mid 9's with the hybrids then cranked it up and it was nice and tight. Wed I'll be at my permission 50 to 125 yards. Using the hybrids as zero, the AEA's were down about .75" and to the left a touch.

Oh, mine wasn't less than an M4, I went a touch overboard on it. Matt tested it it worked, I got it and the reg went bye bye, sent it back he fixed it, then I started tuning it, months later I finally found the magic....at least for that day. Checking it again tomorrow then out it goes for ground squirrel splatting.
