JLK .22 52gr LD bullet

These were mentioned on an earlier thread, so I ordered a hundred to try in my Cooper 22-250. Shooting 50 gr. Nosler, Hornady, and Sierra varmint bullets -.005 from lands in front of 38.7 gr. H380 my gun shoots consistent mid .3's 3-shot groups. Seated .001 into the lands, the JLK's shot the same. Seated -.005 off the lands they shot in the mid .2's. I called back and ordered 500. I have a chrono coming, and will report back with speed and more test groups. So far they look good. Mr. JLK tells me the BC is .302. I'm hoping to shoot to 500 yds and beyond with this load.

Have you tried hunting with them yet? I'd be interested to hear how they preformed on coyotes.

Re: JLK .22 52gr LD bullet

Hello Mr Coyote, the skiing's great! I spent a couple of days last week enjoying the views and skiing Highlands Bowl. I did tell JLK I heard about the bullets on this site. Tim I haven't hunted with them yet, I just fired a few groups today to try get a feel for how they might shoot. My wife and I are headed to Moab (Utah) tomorrow for some mtn. biking. She surprised me when she suggested I should bring my rifle so I could try it long range. I'm going to try get some shooting in at 5-600 yds., and pop a prairie poodle to see how they work.

Just ran the ballistics on those bullets-- turns out you ought to be able to realize about a 100+ yd. gain (with the same external ballistics) over the std. 55's.

Re: JLK .22 52gr LD bullet

Utah was cool-50's and 60's. I didn't get a chance to shoot until sunday morning, and at daybreak it was blowing around 5 mph, with some gusting. My hold was 12" into the wind. After a couple of sighters on a dirt clod, I shot a 3-shot group of 1.76 that was 1.66 on the horizontal plane and .55 verticle. second group was 2.77, 2.77 horizontal, .81 verticle, and a third group was 6.16, 6.16 horizontal, 1.54 verticle. At this point, about 7:30 am, the wind was blowing too much for testing, so I packed it up. All shooting was at 481 yds. I chrono'ed a few groups this A.M. Shooting 38.7 gr. H380 from a 24" bl. av. velocity is about 3525. My first group was a .13-three shot at 100 yds. After 20 minutes sitting and admiring an 1877 .500 Nitro, and an 1850 .54 cal muzzleloader the guy next to me was shooting, I resumed shooting. My ammo had been sitting in direct sunlight, and now speeds averaged slightly more than 100 fps faster. My next three groups were .55, .319, and .518. I'm not sure how much my shooting form affects these groups, except to say that this rifle shoots well enough to really reveal the flaws in my technique. I am learning a lot. In all, this mornings Ag. was .379, which is in keeping with the average over several hundred shots. I never had a chance to test performance on a prairie dog. Before leaving I checked with the UT division of wildlife and was surprised to find that they now protect the white-tailed PD's from April 1 through June 15, during their "reproductive cycle" due to a serious decline in their numbers. I only saw three or four 'dogs the entire time.
