338 Lapua & 225 Accubond - Need load Data

[Buckmaster]

I have H-1000 & IMR 4350 that I usually use for 300 SMK's.

Anyone use these powders with 338 lapua & AB's?

Thanks

Buckmaster: I'm using 101.5gr of H-1000 in my 338 lapua with 225gr ABs. I'm getting 3173 fps at approximately 10' off the muzzle. You'll want to work up to this, of course. I'm pretty new at this so I'm hoping you'll get more responses than mine. I'd like to see what everyone else is using! -- Don

I've used H-1000 with hornaday 225's. My rifle liked 96.4 grains. max is 101, min is 91 per Hodgdon's website.

Thank you Meister. Your comments threw up a red flag for me. I was going off of memory (which can be a chancy /ubbthreads/images/graemlins/crazy.gif proposition for me). So I trudged down to the barn and checked my data - it is 100.5gr, NOT 101.5gr. Sorry about that Buckmaster.

Meister, how far off/into the lands are you seating for your load? -- Don

I had the same results between .002 off and .003 in. No change in velocity or accuracy.
