I`m down to 2 of them now, but did have 3. As for powder them seem to shoot very well with any powder in the burn rate of H-322 to H-335, AA 2230 to AA 2460 or any other near these. @ of the 3 rifles shot best with the 32 gr. Sierra bullets and 1 with the 32 gr. Hornady bullets, but all 3 rifles did well with both. The 39 gr. Sierra bullets shot pretty good in all 3 rifles, but none of them would shoot the 40 gr. Hornady bullets worth a crap. For groundhogs and PD`s ect, the Sierra bullets work great, but they have a jacket thickness of .009 and are to thin skinned for coyote. The Hornady bullets have a jacket thickness of .014 and do a much better job on coyote, but the best bullet for coyote is probly the 35 or 40 gr. Berger.
