Welcome to Grand Master Bullets!
At GMB we are proud to produce a quality cast lead bullet at a very reasonable price.
We use a foundry alloyed 6% antimony 2% tin alloy to produce bullets with a Brinell hardness of 16.
Through years of development and attention to detail we are producing some of the finest quality and consistent cast lead bullets in the business.
Note From Jim Gowdy - Owner
I tell it like it is. I am far from an expert, but do have a bit of experience in the lead bullet world.
Although cast lead has been shot down range as long as firearms have been around there is quite a bit of confusion and misconception around when it comes to bullet hardness and lube and how they relate to barrel leading. These misconceptions need to be sorted out in order to eliminate some of the bad reputation that cast lead bullets have been labeled with. Knowledge is power and I am far from having a corner on the power market so for all you out there who have a better seat in the power bowl than I please send additions to this page to me via email and I will gladly put them up here and give you credit.
1. The harder the bullet the better.
This is by far the most widely carried philosophy and also the most incorrect. A lead bullet that is to hard cannot expand to seal the bore of a gun (obturation). If the lead bullet doesn't obturate the pressure of the expanding gases behind the lead bullet that are pushing the bullet out the barrel will be allowed to pass around the bullet causing lead to be stripped from the bullet and deposited in the barrel of the firearm aka leading.
2. A 44 is a 44 or all bores are created equal
Yes gentleman, size matters. You need to know the diameter of the bore of the gun you are shooting. Spend a few dollars and get a kit to slug (measure) the bore of the gun. I don't know how many times I have had guys order 44 bullets and want them sized in .428 only to find out they should have gotten a .430. Again if the bullet can't obturate it can't perform.
3. Lube doesn't matter
Anyone who has purchased lead bullets with lube that has melted and run out of the groves or smokes to high heaven when fired will agree lube does matter. If you get leading near the muzzle, quite simply your lube sucks or isn't enough to do the job. Your lube is running out before the bullet gets to the muzzle. If you get a lube "star" at the muzzle crown you bullet has plenty of lube and is working well. If you have a lead "star" at the muzzle crown, you are running out of lube. You might be able to reduce the velocity and be OK. Try that first. The quicker you push a lead bullet, the faster it runs out of lube.
4. Billy uses this load so it will work for me.
While everyone shares load data with each other remember this should be a starting point. Every gun is different and will react differently to different loads. It seems that in the rush to save money by reloading we seem to have forgotten that one of the benefits to reloading is that we can experiment with loads, bullet weights, and designs to figure out what each gun likes best. I have guys call me all the time who tell of developing a load for the gun they use and how much fun it was and how much they increased the accuracy of the gun. Just remember guys HAVE FUN.
