WC735 and 69gr SMAK's 223

[Mikeyman]

Hi all, did a search and came up blank. I have a bunch of this powder and projectiles and was wondering if anyone can share their recipe. Plan to use this for service rifle. All I can find is data for 62gr fmjbt bullets. Thanks.

The only reload data I have ever seen for WC735 is "5% faster than H335". The Hodgdon Website for Sierra 69GRHPBT says startling load of H335 is 22gr, and Max load 24 gr. So the WC735 equivalent would be 20.9 gr and Max load would be 22.8 Gr. Hope that helps....

Thanks Barry - I have read that too, I guess I could have done the math!

A somewhat related question should I spring for the bench rest primers you long range shooters use with precision bolt guns? Would it make much difference at 500y with an AR15? Do you service rifle guys use the br primers? Thanks.

For what it's worth, and use at your own risk, I use 23.8 grains under a 69 grain pill. Excellent velocity, good accuracy and no pressure signs. I know of guys using slightly more, but I like leaving myself a bit of a margin.

Fwiw, I have never noticed a difference with BR primers after extensive tests myself.
