The .222 I have, is the most un-fussy with regards to reloads or otherwise.
I cleared out my cupboard of all my odds and ends not long ago and I found I had 50gr and 55gr, soft point and hollow bullets loaded with H4198, H322, Nobel Glasgow Rifle No 1 and R7 all with varying charges from 19.5 to 22 grains of powder.
I sat at 100yards and shot them all off just to get the brass so that I could make a fresh start, I also fired off a few PPU 50gr soft point bullets as well.
By the time I had finished, I had a hole about three inches across made by a quick succession of eighty bullets. It started about 1" across and as I speeded up my shooting, it gradually enlarged to 3", had I took aimed/slow shots I could have kept it somewhere near the 1" which I started with.
I have now settled for 20gr of H4198 pushing a Sierra 55gr Hpt and that does for Fox, and Deer where applicable.
