does hornady make GC's for this size boolit? I am quite partial to them, but if they don't, does anyone know who does make them? thankyou--Travis

I got mine from Sagebrush. Good product, good service and good prices. I bought the aluminum checks as I'd never tried them. No actual complaints, they work just fine but, I believe I prefer the copper which could be a matter of taste or resistance to change. Come to think of it that's the 3rd batch of gas checks I've bought from him. One is 8mm and I can't recall the other. I can't believe you'll be dissatisfied.

Oklahoma Reb, I too want to try gas checks in the 9.3 (.366 groove), went to Sage's site, don't know much more than I did before, obvious not enough demand for a specific 9.3 check. So, my question is can the .375 check be squished onto the bullet shank without distorting it too much for acceptable accuracy? In the past I have squished .323 Hornady checks to fit a .318 bore rifle. Had a lot of 'dome' base rejects to begin with but finally built a mickey mouse affair to push down on the bullet nose as the check was seated in the custom Lee .319 seater/sizer. Excellent accuracy, zero rejects. I would like to hear how you make out with gas checks in the 9.3x62.

I use .375 gas checks with the NOE mold for my 9.3x74 and they work just fine. I use a RCBS lubesizer with custom .368 sizing die.

[Oklahoma Rebel]

so the 375's set on the .366 fine in the rcbs? so they would probably work with a lyman 450 too, don't they work the same?

[sharps4590]

Hmm...I couldn't find them on the Sage site either but mine came from there as sure as can be. Says so right on the bag.

Lots of folks use .375's on .366's. From what I've read and heard from those that do is the check either rides up the bullet or the bullet doesn't seat fully. I've not read of the former presenting a difficulty but have heard complaints from those using a bullet with a gas check shank too short for the extra metal in the gas check. Bear in mind I have no personal experience with either.

I use an ancient Lyman-Ideal sizer/luber and it sets gas checks just fine. Can't imagine why the 450 wouldn't. As you said, same principle.

I can't speak to the 9.3 X 62....other than I'd like to have one....but they work fine in my 9.3 X 57 Husky. The case necks were a bit of challenge in the rifle but the bullets worked just fine.

they are on the 2nd page, I found them

Charlie set me up with two different mandrels for the .375 FC III looks like there is .005 difference between two. The 9.3 fit and size just right on the NOE mold that Al makes.

The mould makers vary a bit in their gas check shank sizing for the 9.3mm bullets. Most use a 375 caliber check, and things go better if they get annealed in a lead melt prior to being applied during the size/lube process. I've used annealed Hornady 375 checks on my Mountain Molds 270 grain flatnose in the 9.3 x 62 Mauser (CZ-550). A few makers cut the GC shanks for 35 caliber checks. Check your mould-maker's spec before dropping a bunch of coin on checks or tools to make them.

My next mould for the 9.3 will be Accurate Molds #37-285-D, a plain base to get away from gas checks to a large extent. 285 soft-pointed grains moving at 1400 FPS and entering @ .367" will stop most large-critter nonsense pretty well, methinks.

The mold I got from NOE is a double cavity and drops one plain base bullet. Thought I would see if I can develop a plain base check.

I've got the NOE mold too and I'm using Gator Checks I got through NOE. They snap right on without muss/fuss/bother.

I use Accurate mold with GC made by FreeChex III 0.010" thickness of brass I put it on with Lee custom .368 and after I do a pan lubing with Carnauba wax. Accuracy by 5 shots about 1 MOA ~ 2000fps Left is 308 right is x62
