I called Barnes, they recommended five different loads. One of them was IMR4895 up to a maximum of 53 grains. I loaded 51, 52, and 53 grains with CCIBR2 primers. Average velocity was 1954, 2068, and 2104 respectively. This was with a chrony 15 feet from the muzzle. Considering that I was using the barrel sights accuracy was not bad at 100 or 200 yards. I have on order a copy of the Lyman 38 receiver sight. The spitzer Barnes bullets feed okay out of the magazine. Should be just the ticket for bear or elk out to 200 yards. Thanks for the info. - Mike
