Just finished testing this Green Mountain 26" 416SS turned on centers and lapped 1.2" straight barrel on my TL3.
Can be used on an TL3 or Origin with Hunts Long Range Lug.
Got a bunch of these GM 416 SS barrels in various calibers to test and see how they shoot. So far, every single one has shot lights out and this 6BR was no exception.
I shot 175rd through it with the standard 30gr Varget under 105 Hybrids that shot consistently in the 0.2s and 0.3s with zero load development or seating depth tweaking.
I then decided to do my final test in this barrel by doing a American Reloading components budget load. I used 16x fired Lapua 6BR brass, CCI450, American Reloading 108 ELD pulls, and 29.1gr American Reloading MP540 Powder (similar to AR Comp, n135, 8208)
26" Green Mountain 416SS 7.5t
TL3/Origin 6BR
1.2" straight chambered by PVA
6BR Eachus Chamber (.272 neck, .105fb)
No turn Lapua chamber
Muzzle Threaded 5/8-24
225rd down barrel
SOLD
29.1gr MP540 is Stupid accurate and amazing consistency with a ES 7.5 and SD 2.9 as shown in this 5 shot group!!
