Remage Conversion 6BR 108 Berger
I headed to the range with the Remington 700 Remage conversion in 6mm BR Norma (6BR) to gather some more accuracy data. If you didn’t read the Remage barrel installation post, take a look at Rebarrel a Remington 700 without a lathe: McGowen’s Remage barrel conversion.
The rifle performed well on its first trip (see McGowen Remage Barrel Review: Spoiler Alert- It Shoots) and I wanted to fire some more rounds to expand the data set.
A quick recap, in addition to the 6mm Bench Rest (BR) Norma barrel and barrel nut fromMcGowen, the rifle is completed with the following parts fromBrownells:
- Remington 700 short action receiver
- Badger Maximized scope rail
- Spuhr ISMS scope mount
- Nightforce NXS 5.5-22×56 Mil/Mil Scope
- MAGPUL PRS stock
- TangoDown BG17 grip
- Timney 517 trigger
The chassis system is a preproduction MDT HS3 chassis.
Range conditions were poor. Temperature was 35F, winds were 15-23 MPH, and the sun was at 12 o’clock to the firing line. Group 1 was fired from the bench with a Harris bipod and rear bag. Groups 2 through 8 were fired prone, with a Harris bipod and rear bag. Group 3 was fired at 10X magnification, all other groups were fired at 22X.

Loads were created with the following components fromBrownells:
Powder charges were thrown with aHarrell Classic Culver powder measure. I weighed the first charge and threw the rest.
The 6BR is a pleasure to shoot. Modest recoil and great accuracy make for a nifty little cartridge. Since it won’t feed from stock AICS magazines, each round was hand fed into the chamber.
Average accuracy was a respectable .761 MOA. Given the range conditions, I am pleased. During load development, average accuracy of the five groups was .645″ (.616 MOA). I attribute the better performance to those five groups were fired from the bench in better range conditions. The ten-shot group had one flyer (my fault) that opened it up over 1 MOA to 1.207″. The other 9 rounds were formed a .842: group. Three 200 yard groups averaged .751 MOA, but most shots were disbursed horizontally. Vertical spread averaged .368 MOA!
The McGowen Remage conversion continues to impress me. I’ll be fine tuning my 108 grain Berger load and post the results.
