Silver rapids .223 powder coated bullets.

[Treeman]

we now on 84 test shots, silencer on - off, COL long - short. 2200 -2540 fps. Annealed cases, once fired cases.

I will do last test shooting into a pool to collect bullets.

1 - 9 twist might be too much for this coating.

Some old wisdom said that cast bullets (with GC) should be kept below 1700fps.  I would rate powder coating about as good, so 1700 should be fine. That's what I load my 375 cast GC bullet to.

With S335 you should be able to go to a pretty low load.  Use a filler if you need to go below 15 gn (+/- 60% case fill).  This applies to S335 only, not any other powder.

Then I have me self a 22 Hornet with a big case
