I've spent hours and hours working up a great load for my 7mm using H1000, with excellent results by the way. I've now started to focus my time on getting a load worked up for my Howa 1500 .243. With powder and supplies being limited at this time, I'm thinking of using what I've got since I have copious amounts of it. If I don't get acceptable results, I will obviously invest in more popular loading materials for my load. This is just out of pure curiousity, brought upon by being impatient and not wanting to wait to find more powder
. Last night I sat down and worked up 5 loads each of the following 44grs, 44.5grs, 45grs, 45.5grs, 46grs, 46.5grs, and 47grs. All of these are seated .0075" off the lands, and are using WLRM primers. All rounds are using 87gr Berger VLD Hunting bullets. I have no idea how these are going to shoot, and don't know what my max load is going to be. This experiment could flop for all I know, we shall see. From the research I have done, a lot of guys don't get pressure signs using H1000 even with a compressed loads, and they are typically shooting 95gr+ bullets. Taking careful notice while loading all of these rounds, I found that even with my 47gr loads, none of the loads were compressed. So I imagine that I should be ok all the way up to 47gr, but that's the reason for starting low and working my way up. Another thing that I learned from reading was that most guys that are using H1000 with the .243, are shooting 95gr or greater bullets. Now for my question. Has anyone experimented with H1000 in a .243 using lighter than 95 gr bullets? If you have, what were your findings? I will be sure to share my experience tomorrow with these loads that I have worked up. I'm going to the range tonight to see.
Edit: Any predictions?
