Hello all! so I decided to join LRH after creeping around for a little while lol. I was looking to see if anyone out there has any load data for the Barnes LRX 145g with Reloder 22 in the 280AI? I tried to Google some results and haven't found any solid information, at least in recent history. I looked around on Rokslide, Accurate Shooter, Nosler..... which lead me to here and ultimately joining all of you fine people. I found somewhere online that one guy did a load of 61g to 63.5g of RL22 and max was the ticket. I asked a couple other fellas on this load and they had similar results. Needles to say I built a similar load with a CCI 200 primer and once fired factory Hornady factory barss. at 61g starting charge I was 3100 at the muzzle on 4 shots but had signs of pressure and very heavy bolt lift. So my thought process now is to back off 2 grains and start over. After the 4 shots i decided to NOT attempt to shoot the remaining loads of 5 per charge up to 63g. Long story short does anyone have any new updated data they wouldn't mind sharing with me? By the way I am shooting this out of a factory Kimber Hunter 24" barrel.

Look at Barnes load data for the 7 RSAUM starting load 150 gr bullet is 58 gr of RL22. I know you have a 280AI but 7 RSAUM is similar to the 280AI. I would start at 57 gr RL22 and work up, might change primers also. Just watch your chrono readings. Hope this helps.

It tested rl22 with the 145 lrx in my 280 AI. It shot well with a .8” group but h4831 shot .2 so I went that route. In the end, I tested the 120 tsx and it liked h4831 best And didn’t like rl22 at all but that’s just my rifle, yours may be different

I actually just shot some 162 ELDm with reloader 22 and had good groups at 59-60 grains. Not sure that helps you any but good luck.
