FPS was lower than before as well as SD much higher than before with same load. I've been loading up more rounds to strictly use targets to find most accurate load. I also shot some 240 XTP Mags with decent group of 1-1/2"at 100yds but 8" group at 185yds. I think that I'll be hunting with the 200gr or 275gr XPB's as I have one spot that would be a 200yd shot and they are more aerodynamic than the XTP Mags.

I had been blowing unburnt powder out the barrel along with a drop in velocity using Lil-Gun. I found a happy medium with a muzzle velocity of 2583 FPS. That was just before velocity drop off. I also checked velocity of 275gr XPB bullets and had a muzzle velocity of 2385 FPS.
I ordered two boxes of the new Hornady 245gr SP IL bullets. I only wish they would have a cannalure. I contacted Hornady to find out what they recommend as max velocity for these bullets. They responded with 2500 FPS as max. I'll report back what I find with the new bullets.
