22-250 loads

[homesick]

Any one have any experience with 52 gr bullets with IMR 4166 or Benchmark.

Benchmark for 53 gr Vmax

Benchmark works nicely for me. 33.4 gr. And WLR primer pproduces around 3670 fps and nice tight groups.

I have been out a couple times now with test loads, the rifle seems to favor top end pressures with both 4166 and Benchmark / 52 gr Sierras/ rem 7 1/2s .
700 VSSF / 6X24 Burris.
I have only shot 3 shot groups at this point, right at 1/2' MOA. I'll have to run a few more test groups to make sure it's the right combo.

I use Lapua brass and Federal primers. 30gr of RE 10x and a BIB 52gr bullet equals .3" groups at 100 yds. Rem 700 rifle with a heavy Lilja barrel and Jewel trigger. I always shoot 5 shot groups. I have shot groups as low as .2" but .3" is more common.

Shot a couple more groups today there not .2 or .3 moa but I have a good starting point, the book shows this load with Benchmark and a 50 gr at 3900 fps. I'm using 52 gr and not showing pressure signs.
Cases are Remington not weighed, primers are Rem 7 1/2s / powder is t/- .01
I don't spin bullets or do any thing special. I do trim cases to the same length.
