I have 2. One with a ER Shaw replacement barrel on a savage and a tikka. shooting 200 gr speers, (hornadys didn't seem to group quite as good but they would be ok if that's all I had). Using 46.5 of IMR 4895 in both of them. The savage is a 1 1/8" @ 100, sometimes less but that's a strong constant, the tikka if I do my part is sub MOA. Performance has been, a doe at about 40 yards, in the lungs a clean pass threw she went maybe 30 yards. A 9 that was facing me put his head down to sniff something, shot him between the shoulder blades @ 50 yards, DRT never even kicked but then he wouldn't of if I'd been shooting anything else either. Both were shot with the savage, can't explain it but it fits/feels better than the tikka.
