[QUOTE="MikeMarcum, post: 799579, member: 63603"] That was my fall back position, to fall back to H& H load data and work up, but since powder and primers seem to be so darn rare I was hoping to get there in a few less loads. I really hope to get some supplies before it really counts. I have been over the web and printed books for over 3 months now trying to get a good starting point. The Rifle is more than powerful enough for anything here in Nevada, even at H&H velocities but hoping for a little flatter drop. As well as trying to maximize my powder rations. And since I have never shot 225 in it before, have no idea on accuracy. I have some older reloads for 235, 285 and 300s that I got from Dad when he gave me the rifle. But no real documentation and 4 or 5 kinds of brass. But after about 10 rounds of full load 285 and 6 more of the 300 my shoulder was complaining about the recoil. Not my favorite bench rest rifle. My Manual ( One Book / One Caliber Vol 2 Weatherby Copyrighted 2004)shows for the: 225 HDY SP with starting loads of 96 gr. of H4831 for 2813 fps - up to 99 gr Compressed for 2957 fps. In H4350 shows a starting load of 89 gr at 2939 fps and max out at 94 gr. and 3070 fps. ( no compression listed for the H4350) and Thus since I do not have any of the H to compare to the IMR for volume. They show up on burn rate but have not seen anything to show volume to weight data. The Hodgdon Website shows Data for H&H with both 4350 types and compressed loads of 83 gr for H4350 and compressed IMR 4350 of 79 gr. but for a 250 gr bullet. at .5 grain that is a bunch of rounds to get to 90 or so, but I may have no other choice. Thanks for the help, it may just be time to drive a bunch and go to a few gun shows to find known loads powder. If it was just a matter of cost and shoulder pain I would try lots of loads and powders, I love to geek out on data and love to shoot. there is lots of good places here as Nevada is mainly empty BLM land and mountains everywhere so good backstop are never an issue. Most of my Reloading is for Cowboy Action 45 Colt and Varmint rounds, the CAS is not so hard and 22 centerfire is not 375. I was hoping for an accurate load of about 2900 fps (225gr BC .320) as my new Scope is the Redfield Revenge with the DNS Accuranger and at my altitude (5000 ft.) using the Hornady Website Ballistics Calculator it should match the drop of the 243 dial almost perfectly to 500 yards (zero MOA difference to 300 yds., 0.1 at 400 and 0.3 at 500 - the dial uses 100 yard zero) Have fun and hope to hear more from anybody on this issue.
