Home Forums Gear Free Classifieds 500 Jeffery project rifle

Time to winnow out the unfinished projects from the safe. This one has been on the back burner for more than a few years so I’ve forgotten a few of the details. As I recall the barrel blank is a .510” 1-15 twist Douglas cut to 25” long and 0.82” at the muzzle. Barrel band front sight and sling swivel are from a Ruger #1 458 barrel and have been bored out to fit the barrel. I know there have been a few different dimensions for 500 Jeffery chambers and I don’t have the correspondence from the smith on what reamer he used. He did cut the throat a bit longer to allow using 50 bmg bullets, so if you want 2/3 the velocity of a bmg burning ½ the powder it’s an option. My starting loads used 100 gr of RL-15 to push a 600 gr cast bullet 2200 fps. My plinker loads were 40 gr of unique that push the 470 gr cast bullets ~1100 fps.

The barreled action weights 7.8 pounds, not a bad thing for a rifle that dishes out the recoil and then some. It’s an Enfield action and the bolt handle has been straightened. I’ve seen the dogleg draw blood on my 458 Lott Enfield so didn’t want to give this rifle the chance, trigger and safety are original. I was going to tackle the magazine and rail work but didn’t want to risk screwing it up so then planned to have Duane Wiebe make custom bottom metal and work out the rails for feeding. So as it stands it’s a single shot. There are at best a handful of smiths who should be trusted for the magazine and rail work.

Included is 45 pieces of brass, 25 Star headstamp 15 of which have been fired a few times, 10 unfired, 20 are Hornbear headstamp and unfired. Dies are from CH4D and include a 1 ¼-12 bushing to allow the 1”-14 die bodies to thread into a rockchucker or similar press. 40 Barnes 570 XLC bullets, 80 cast 470 gr from and LBT LFN mold and a dozen 695 gr AP milsurp bullets pulled from 50 BMG.

If you just have to have one the most powerful sporting rifles out there, a 50 caliber is something you don’t come across every day.

$750 shipped. I’ll ship the barreled action to your FFL and the brass, bullets and dies to you. Brass, bullets and dies alone are worth over $500.

What did you have this in as far as a stock goes?

It was an old sporter stock that had a few cracks forming and has subsequently been trashed.

Reduced to $700
