burnt my first custom barrel 26 up in 500 rds from running 100gr stuff 4k, rebarreled it run nothing but 124 hammers in it now at 3525 fps, it will bang a 10 in plate at 1000 yds all day long! Drops whitetails like lighting, only shoot it 20 or 30rds a year now, should last awhile.
Just a word of caution ... I sent some 127 LRX down the pipe at 3550 FPS ... TWICE... and the Nosler brass was done ... the primer pockets wouldn’t hold any primers ... and here in Canada they’re selling for $120 for a box of 25 ...something to consider when you’re chasing velocity
3550 is smoking. 3450 is as high as i wanted to go. So far have gotten 4x reloadings with Nosler brass. I only put 15-20 rounds downrange each year so cost is minimal. Its a hunting rifle for me. My goal with the 26 is to get scorcher of a hunting round that is very consistent then stop and milk the barrel for multiple years. Plenty of other rifles to punch steel and targets.
