Thread: 6x45/6mm223 projectiles ?

@Doon, you might want to think about dialling those loads down.

Hodgdon provide data for 6x45. Under the 95gr section there is data using Accurate and Ramshot powders. None of the speeds exceed 2600fps and they're all right on 55,000psi of pressure. I don't see how you're going to get ~175 fps more from a 4" shorter barrel with 8208, without it being way over that.

For the 70gr and 85gr bullets, you're at the max load and again you're getting more speed from your shorter barrel. The pressure on the Hodgdon site is given in CUP for 8208 though which is a bit vague.
