Nice rifle. Good shooting. I'm getting 3380 fps with 130 Barnes TTSX over a full case of Superformance powder, Winchester brass, 210M primers in my 270 Winchester with a 25.5" Hart barrel. 3320fps in my other 270s with 24" barrels. It's my first time using Superformance powder.
this is my second barrel the first one I got 3414fps with 129gr lrx with RL22 cci 250 primers 1/4 group . this barrel I'm getting 3454 fps with 129gr LRX . H1000 cci 250m and the same 1/4 group I got the ammo from factory Nosler I removed the e-tips 130s and saved them and put in some junky spear 130gr to fire form the brass . I did this because I couldn't find 270 ism brass anywhere
