Well I went and bought a 10" barrel in 222 Remington for my contender. Spent some time at the reloading bench and loaded up fifty rounds with some Accurate 2230c powder that I have and some 46 grain remington Hornet bullets and CCI 400 primers. I started with 21.5 grains and moved up in half grain increments ending with 23.5 grains. I found the load it liked was 22.5 grains of the 2230c powder. I was able to shoot three 3 shot groups that measured 0.61 to 0.72" with this load. It open up to 0.88 to 0.97 with 23.0 grains so I settled with the 22.5 grains. This load will be my primary PDawg load. I stopped on the way home on Thursday and did this to a few P Dawgs.
Yes it will work just fine. For that purpose.
