Jordan,
The freebore doesn't seem to hurt accuracy with other bullets, for what reason I dunno. My first .257 Weatherby was a Vanguard Sporter (walnut stock) that would group three 100-grain TSX's (the TTSX wasn't around back then) into 1/2 MOA out to 500 yards, as far as I ever shot it. It also shot flatter and with less wind-drift than any ballistic program predicted, probably because extra velocity tends to increase BC, and I was running them at 3550 fps from a 24" barrel.
Replaced that rifle with a NULA Model 28 that shoots even flatter, with less dift, using with 100-grain TTSX's or E-Tips, but weighs two pounds less.
