Ok.. I can't find a thing about loads with this combo... I'm hazzarding a guess at 24.5gr or 25.0gr of H335 sounds good?

just happened to be looking up H335 on the 6.8 thread;

from Hodgdon's load data page (http://data.hodgdon.com/cartridge_load.asp), it list Sierra 63gr SP at 22.5 starting and 25 max. Is that ok for the fmj?

22.5 sounds kinda low for H335

I'm loading 25gr for 62gr of WCC844 which is the same as H335;)

OK.. I loaded up 10rnds or 25.0gr of H335 and averaged 3025fps and all rounds kept in the 10 ring froma bench out of a GI chrome lined 1-9" barrel. Looks like I'll stick with the 25.0gr of H335...

WC844 is supposed to have the same burn rate as H335. I think they use around 25.0gr of WC844 in M855.

24.0gr should be a safe starting point. 23.0gr would be even safer.

I load 26 gr of WCC844 with a 62 Gr SS109 projo. NATO ammos pressure is over Sammi specs... and run about 3200FPS B2B

I have loaded 25.0gr of H335 with 55gr BTSP for years without a problem. Assume it would work with 62gr. also.

Why do you wanna shoot 62gr SS109?

If you're buying surp, that's one thing. If you got a ton of surplus pulled bullets, sure.

But if you're taking the trouble to handload for some measure of accuracy on top of savings, that's another ballgame: the steel penetrator core reduces accuracy since its positional placement within the bullet is not that precisely controlled in mass manufacture. M855/SS109 accuracy spec is 4MOA, though USGI loads appear to be running 2.5MOA (subtracting out other factors like the rifle & shooter).

There are indeed 62gr non-steel-penetrator bullets available - these are used in Fed American Eagle 62gr ammo; these are likely to be quite a bit more accurate.

I was lucky to come across some 62 grain commercial ammo awhile back for 375 shipped for white box but now I think finding 62 grain bullets and reloading the same type bullet is the way to go but finding the range friendly bullets can be a problem that Im working on, both places tell me to call back next month.:cool:

Yes I'm loading a ton of surplus bullets.. being able to hold the 10 ring at 200yds on a SR target is well within my reqirements for this type of bullet.. This is basic blasting and SHTF ammo... as I also have a ton of 55gr pulled FMJ's that are loaded also for blasting (6K worth)
