OK, so I made it out for a couple hours of range time today. Other than a Garand shooting a bit lower that I'd like (I'll have to zero it later, I ran out of time), the Remington 700 did well.
Here is the first target. Nine rounds total of Federal Premium, loaded with 150 grain Sierra Game King BTSP, Federal Premium with the 165 grain Barnes TSX bullets, and a couple of Lake City (CMP) rounds with a 1974 date stamp. Overall, not bad. These were my warm up, knock the cobwebs off and fouling shots. Far left and lower left are the LC rounds, the rest of the cloverleafs are Federal stuff. The ones outside the pasted target were me fiddling around with some elevation and windage adjustments and were purposefully directed off target. Honestly!
And here is the target where I went to work after letting the gun cool about 20 minutes.
The bottom "crescent" is the first 3 rounds, the upper "triangle" is the second group of 3. The rifle (or the shooter, most likely!) didn't group as tightly as I'd have liked. But everything was in the 10, with a couple touching the bullseye. Not bad. Better than I've ever shot with Remington or Winchester ammo.
I've taken exactly one animal with the Federal Premium/Barnes TSX combo - a 80-90lb sow a while back at a range of about 60 yards. The bullet struck the heart and she only made it a few yards before she fell. I was sold on the stopping performance of the Barnes TSX bullet at that point. As an added benefit, I know I can run this stuff in my rifles for any big game in California. No need to worry about testing new brands or batches of ammo when hunting in lead free vs. non-lead free (i.e. California Condor Friendly) parts of the state.
