I bought a bunch of .505 on clearance from Cor-Bon (RIP). “Expedition safari”. Some of the brass showed evidence of failing. Jamison I believe. No luck with Cor Bon as they went under. I don’t want to blow up my AHS .505 so is there a company that can pull components and reload these correctly? I have the dies but would rather it get done properly as I have yet to reload this caliber and have a million other projects in the fire. A point in the right direction would be great. I have brass to furnish. Any help is appreciated as I’d love to shoot it up. PS Cor Bon sucks

Is there any way to tell a load is bad? I fired a bunch no problem but then ran into a couple with split bases and stopped shooting them

jamison brass is highly questionable, by vintage -
pulling the bullets is easy - dispose of the powder, IDK on the brass --

HIGHLY recommend federal 215/215m for this giant case -- hang fires in big bores is somewhat stressful

What jeffeosso says…he is 100% on primer choice and hangfires, I’d pull the bullets and throw the cases and powder away. Rock River has Norma brass.

What’s the best way to pull the bullets? Collett?

I don’t have a collet for .50 caliber so I use a “bionic wrench”, a plier like tool that grips like a collet. Just raise the round thru the top of the press, grip the bullet and lower the ram. There are a couple of sizes of the wrench, I have two and they work for several calibers. One does have to grip the wrench pretty hard for heavily crimped rounds.

jamison brass had some great runs, and some very soft runs - when we were doing pressure testing on some big wildcats, loads that had been perfectly safe, as in "that might be too little powder" damaged brass from a new batch - i think the matter/process was corrected, but i haven't bought any from there forward -

Last lot of Jamison .505 Gibbs brass I got, 37 of 40 brass neck split when seating bullets, all the way down thru the shoulder. The three that didn’t split, split when fired just above the head. No more Jamison brass for me.

Wow. Terrible. The ones I fired seem to fire fine. Is it in advisable to fire them to get rid of them? Or is it totally unsafe ?

Pull the bullets, its easy..look the powder over carefully and in your case I suggest you toss the brass as you don't know its use history, and Jamison suffers a bad reputation it seems..

That "bionic wrench" is a great idea. I wonder if it will work for my 577 NE. Thanks, Brian

Bet it will…works like a charm on .505 and .474. Pretty reasonably priced, too.

Excellent~ Thanks, Brian

To solve hang fire problems.

Not in this case, but if it does.

Put a couple of grains of Bullseye at the bottom of the powder.

Add the powder on top.

This is what we use for our 700 Nitro Express.

whatever tool you choose to use,
run the round up to the top of your reloading press, grab onto the bullet, lower the round, might consider some cloth tape on the jaws

I have done so with good success

The cheap crimping pliers used in auto electrics work well. They have flat jaws which sit nicely on the top of a reloading press and usually 3 or so different sized crimp holes, often plastic coated, which will enable a whole range of bullet calibres to be gripped and pulled.

My Jamison 500 Jeffery brass has been flawless. Sorry to hear about your experiences with their 505 brass

I made my own inertia puller some years ago. Very DIY basic but it worked well for 416 Rigby & 470NE



I used a bit of rubber tubing so that the bullet nose did not get damaged.

Insert the round into the poly tube & after taping up the round in the tube, I just throw it onto to a block of wood and catch the rebound.

The rubber tubing needs to be replaced after about 7 or 8 rounds as the impact on the wooden block cuts through the rubber.

I have a collet bullet puller for my 500 Jeffery works great when I need it.
