And what length barrel for what speeds etc? With amaxs or 180 bergers? Short or long actions?

Thanks Cam

I've had a couple, great calibre. ran amaxs in both, a 23 inch tube got speeds up to 3100, but backed it off to around 3000 I think it was. And a 26 inch tube that I ran at 3140 no problem. compared to my rem mag which maxed out at 2950 in a 24 inch tube

I shot the barrel out on the 23 inch one and currently swapping 26 barrel onto that. It's a browning TI so makes use of the shorter action length
