Got about 150 rounds put together with H380.
55 gr Remington FMJ/molyed. and the spectrum of powder from 37.4to 41 gr.
I expect I'll find a group somewhere around 38 gr. Does anyone have any load experience with H380 at the upper end(41gr) loads?

I post up some results after tomorrow

thanks

danev2,
I load 38 grains behind either a 55 grain Nosler balistic tip or Hornady V-max both will group under half an inch. Velocity is right at 3500 fps, this is out of a bone stock Browning with a 22 inch barrel.
Hope this helps.

I shoot 38.5 gr of h380 pushing a 55gr nosler balistic tip.I am getting some very exception groups out of this load.

I use H380 in my 22-250 Ackley, load 40 grains behind a 60 grain VMAX, does very well.

Do not overlook Varget as your powder of choice in your 22-250. It is temperature tolerant, burns very clean and shoots fantastic groups in my heavy barreled 22-250 with less powder charge than H-380. At least give it a try.
