Home Forums Hunting & Shooting Express Rifles and Big Bores Only 450 G&A Short

I called Loon Lake precision yesterday and found out they will make the 460 G&A to the original specs. I should receive it in the next 3-4 months.

Unfortunately I was told that due to the reamer dimensions they can’t make it as a pull through. I’ll need to get a set of headspace gauges next.

Planning to test a couple of magazine followers I have in the M-70 action I’m planning to use. Been looking at a few barrels in 458 Win Mag as a starting point to rechamber. I’ll need to see if I can get one without the cartridge stamp.

Next step is to run a 404 Basic case through a backed out 404 J full length die and expand the neck to 458 in the 450 Rigby die. Need to get an idea of seating depth with the 450 & 500 grain CEB BBW #13s to keep COAL at 3.6” max.

Starting to be an interesting project.
