I am developing a load for plicking and practice using W748, once-fired WW brass, WSR primers and 55gr. FMJBT bullets.

I'm using Winchester Data that shows 26.2gr. max.

My firearm is an MT6530, 16"bbl. 1-7 twist.

I would like to know what the starting load should be, in your experience, to insure proper function.

So I don't load 20 or more rounds of test loads starting at 10% below max, that don't function it.

Thanks,

Sgt.K
