If the bullets need a gas check, then they will probably have one installed already.

I've tried commercial cast bullets in one of my pistols, but got such terrible results that I gave up on them. Often, the bullets will be undersized or too hard for the particular gun and you get poor accuracy and leading. I ended up melting down about 400 of the remaining bullets and recasting them when I started casting my own. Your mileage may vary.


One special piece of equipment you will need whether you order comercial bullets or make your own is a Lyman 'M' die in 30 caliber. This die will bell the case mouth slightly so that you don't shave any of the lead off the bullets when you seat them, you then set your seater die to remove the bell in the case or you can crimp.

You are going to want to slug the bore of your rifle as well- http://forum.hunting.net/asppg/tm.asp?m=864124


You need to be sure that the largest driving bands on the bullet are at least .001" larger in diameter than the groove diameter. If the grooves in your rifle measure out to .308" which they are normally very close to on 30 caliber rifles, then you need a bullet that is sized to a minimum of .309"


If you want to try to make your own, its not too expensive to try your own, though more expensive than your initial box of commercial bullets will be, here's what you can get by with:

Lee 150 gr. or 170 gr flatnose mould: $14
Lee .309" sizing die $11 (comes with a bottle of Lee Liquid Alox, which is a very good lube)
1000 hornady gas checks $18
Camp stove with an small old cast iron pan or pot or $30 Lee precision melter.
+
Lyman dipper $12

Or a cheap Lee melter such as a production pot IV which is a bottom pout where you will not need a dipper. $47

A bucket of used wheelweights from your local mom and pop garage.

whether you want to try to cast your own or not, I would reccomend a Lyman cast bullet handbook- costs about $15, its an invaluable reference book as well as a reloading manual.

I think in the article they used 4198 and SR 4227 powders, but for what its worth, you almost can't go wrong with Aliant 2400- this stuff is not sensitive to position in the case, you don't need any fillers, and an accurate load can be found most of the time by starting with a charge of 16 gr.
