PLESE NOTE: Krieger Barrels, Inc. does not offer any pre-fit or drop in barrels for any bolt action rifles. We can sell you a rifled and contoured blank (no threads/chamber/crown) or we can fit it to your receiver if the action you have is listed on our list of accepted actions and we have a chambering reamer for the cartridge you want to use.
We only offer the .30 "Tight" caliber barrels up to a 1-12 twist. The reason being, we have seen pressure issues arise when using heavy, long bearing surface bullets in this tight bore/tight groove configuration. We strongly suggest against using bullets heavier than 175 grain, and/or magnum pressure cartridges in any .30 Tight caliber barrels due to the dangers of high pressure and the increased chance of copper fouling.
Krieger Barrels, Inc.
ALL barrels are rifled with a right hand twist.
