[QUOTE="barnesuser28, post: 940230, member: 43468"] I had to send my dies back to whidden as they were oversizing the brass, causing a few to get stuck in the die, but I got my rifle back from my uncle after getting bedded, and I had 8 rounds of loaded ammo left, so I pulled the bullets and decided to try some RL33 in the gun. I loaded up from 82.5 (almost max retumbo load in Rich's gun) -89.5 grains. 85.5 was 100% fill and 89.5 was highly compressed, I left the loaded rounds to sit for about 30 min and none of them were pushed out from the compression. Bullets were seated .040 off lands, so they can fit in the mag. Here are the results, based off the magnetospeed: 82.5 2807 fps 83.5 2818 fps 84.5 2890 fps 85.5 2929 fps 86.5 2994 fps 87.5 2995 fps 88.5 3067 fps 89.5 3092 fps 83.5-85.5 went into a sub .5 MOA group 86.5-87.5 were 2 inches higher and just over .5 MOA apart 88.5-89.5 were another 1.5 inches higher than the last and were about .75 MOA apart. I think I have nodes at 83.5-85.5, 86.5-87.5, and 88.5-89.5 I will try these four loads and see which one shoots the best. 79 grains of H1000 for around 2900 fps 85 grains of RL33 for around 2910 fps 87 grains of RL33 for around 3000 fps 89 grains of RL33 for around 3075 fps I don't want to try retumbo as I don't have very much and it is almost impossible to find any.
