I bumped up the load in 1/2 grain increments making it to 37 grains. The recoil was quite brisk at 37 grains and accuracy was terrible. My 100 yard group at 36.5 was about 2 inches smaller, right at 1 1/2 inches. I had no pressure signs working up to 37 grains.
I started my work up after a member had done some hunting with the deep curl bullets and wanted to give them a try. I believe another one of our members posted quickload data and said 34 grains was a bit light on the powder charge but don't quote me on that one. I'd have to dig thru all the posts.

That would have been me and I just re-ran the numbers. According to QL 38gr Lil Gun and a 300gr Speer Gold Dot, which is the same as the 300gr DeepCurl, shows around 34k psi at a COL of 2.18 (to catch the cannelure).
I have loaded them myself, though in my rifle, the accuracy results were not acceptable for me. Of all the 300gr bullets, the XTP Mags had the best accuracy. I tried several powders with them and could not obtain the accuracy I could with lighter bullets like the 275 XPB and of course the 250 FTX. My impression with the 300s was that they were on the verge of accuracy, but needed a little more velocity than I felt comfortable pushing them to.
