Targets. Just plinking really. That 150gr Accubond LR is the only bullet I’ve found with a decent BC, but they’re expensive.
I’ve rung steel out to 500 yards, but haven’t tried further.
I honestly don’t make alot of time for it because the scope I have on it isn’t great for long range, and the .277 bullet selection isn’t great.
The best thing about that cartridge is powder selection. Seems like every rifle powder out there works with the .270 win.
