20br and 20bra for pdogs

[L.Sherm]

I believe RL15.5 is worth exploring more with the BRA, I dabbled in it showed promise closer to spring I think I will give it another try.

It’s like H4350, RL 16, RL 17, IMR4064,

Can’t get enough in case to get above 3400fps w: the 55gr…
The 39/32, 40, 35gr ought shine though!!!

Try portable electric toothbrush, better than drop tube.

Doubt it- powder too slow to start with

Not me. This is from a customer. And this is fireforming.

Be interesting to see where his pressure shows up, if any

He said the case is full at 34.7 grain. Also, this is fire forming. I told him to go with 33.6 and do a seating depth test and call that a fireforming load.

A customer is sending me a 20Gt reamer.

Oh my.

Go to a faster powder like 15 after forming and he will get more in there and I bet better accuracy.
