I finally got to give the Speer Deep Curl 300gr. bullets a try today. I was pleased with the accuracy considering I had a 10-15 mph wind that was gusting from right to left. Im sure the groups would shrink to close to an inch on a calm day. I sighted them in at 2 inches high at 100 yards. I was using my Encore Endeavor with 110gr. of BH209, Win 209 primer, Harvester short black sabot, and of course the Deep Curl .452/300gr. bullet. My question is, what kind of velocity should I be expecing and what distance should I be good to sighted in 2 inches high at 100 yards? Thanks for the help and all the recommendations for using this bullet. Can't wait to try them out on some game in the coming weeks. I promise my next report with them will have pics.
