Am waiting on paperwork and ready to build out my RRA 9mm SBR w/ 7" bbl. My question is.... those of you who have a SBR in 9mm.... what ammo do you use and do you by chance reload any? I have a load for 147 grain bullets, 3.8 g of VitVor 340 shooting out of my Glock for IPSC. I'm in hopes my SBR will function with those just fine. Would be great to shoot those same ones for just plinking with it and then load up with some "good" 9mm when needed. Any help/insight/suggestions would be greatly appreciated.
