[QUOTE="Stammster, post: 2300483, member: 114381"] I also bought them earlier this year. They were coated with a gray material, that I assume in HBN, rather than Moly. Here are the results in my Kimber 84M 6.5 CM with 22” bbl (1:8) using: RL26 Starline Brass (new) with 52.05 gr H20 cap Case length 1.912” COAL 2.660” CBTO 2.095” .174” jump (seated with cannelure at neck) Worked up 3 shot ladder from 45.5-48.5 gr in 0.5 gr increments 70F, 10 mph wind 100 yds 3-31-21 45.5 0.85” group 2705 fps. ES 10 46. 1.04” group. 2733 fps. ES 2 46.5. 2.06” group 2 shots touching at 2750 fps, and the flyer at 2785 fps 47 1.06” group 2774 fps ES 6 47.5 0.93” group 2804 fps ES 3 48 1.94” group 2820 fps ES 25 48.5 1.92” group 2850 fps ES 15 Slight bolt lift at 48.5 47 and 47.5 shot the same POI I’ve worked up another batch 46.9, 47.1, 47.3 and 47.5 gr - but it got too hot here in Texas and I haven’t shot them yet. This gun shoots 143 ELD-Xs at 2850 fps at 0.5 - 0.6” groups between 0.090-0.120” off the lands - due to mag length restrictions. But it took some work to get there. I’m pretty happy initially with these Deep Curls. No weird pressure signs, good ES, and similar velocities vs charge weights as other uncoated 140 class bullets. I’m planning on using these for sub 300 yd shots on deer and hogs this fall, so the velocity and accuracy performance is acceptable to me. In fact they outshot the loads I worked up with 140gr Partitions, so I sold all remaining bullets - and plan to stick with these 500 deep curls for the future. I might play with seating depth also, but tend to seat bullets with a cannelure at the neck unless I can’t get them to shoot. [/QUOTE]
