204 ruger blowby?

Post by 07yzryder »

I'm not sure that's the correct term, but basically I'm getting lots of suet on the case and my bolt is extremely dirt after 30 rounds. I haven't had this issue with the 223, 300, or 458 so just wondering if it's common on 204 ars?

I got the same thing in my Cooper. I think it is either low pressure or a slow pressure curve.

I switched to IMR 8208 XBR and got better accuracy and NO blow by.
