Browning xbolt hells canyon LR help!

[Wild7mm]

X-Bolt HC LR 7mm Rem Mag

Winchester cases, RE26 powder, FED215M primers, 165gr GameChanger

We also shot AR2217 powder with 162gr ELD-M projectiles which gave bug hole groups. Even with factory ammo this rifle shoots lights out!

The trigger was absolutely rubbish so got a mcarbo spring and it completely changed it!!

IMR 4350, 180 Accubond, CCI mag is # 1.
IMR 4831, 180 Accubond, CCI mag is # 2

I have to watch the pressures with the 4831. To get better accuracy with the 4831, I'm shooting a compressed load. My pressures are being extremely temperature sensitive with the 4831. I only shoot that load when temps are 70 or below.
I have not had pressure problems with the 4350.

I'll let the photo speak for most of it but this was load development on new rifle first time shot. CCI 250 primers, bore sighted rifle and zeroed at 50yds and shot these at 100 yds. 0.015 and 0.020 of the lands.

I looked online last night and found that aftermarket trigger spring, mcarbo, and ordered it! $20 for a spring is better then $175 for a hole new trigger! Thanks for the help!!

I did the same thing on my hells canyon long range. Mines in .300 WM and shoots sub .5 MOA out to 500 yards (haven't shot it further yet).

As for 7mm rem mag bullets you should check out Hammer bullets. That 8 twist will stabilize some of the longer 169 or 177gr hammer hunters. Or drive the 155 grainers pretty fast.
