Cutting Edge 10mm and .45 HG Solid Bullets

5pins · April 28, 2018, 05:00 PM

I had the opportunity to shoot some Cutting Edge .45 ACP and 10mm solid copper bullets in some Clear Ballistics Gel. Test pistols were a Colt Delta Elite in 10mm and a Colt 1991 in .45 ACP with 5-inch barrels. Two shot each into four 16 inch blocks of Clear Gel.

The first round out of the 10mm hit at a velocity of 1104fps and penetrated to 50.25 inches. The second round hit at 1118fps and penetrated to 52.75 inches.

Round one in .45 ACP had a velocity of 1052fps and penetrated to 42.25 inches. Number two hit at 1025fps and penetrated to 41.75 inches.

What weight were the 10mm bullets?

If they were 180gns, the velocities you cite barely exceed .40-level ballistics.

For 180gns, try 1300-1350fps.

If 200gns, try 1250fps.

Then get back to us on the penetration stats.

The 10mm was a 190gr bullet. When I tried pushing them faster is was getting signs of very high pressure. Solid copper bullets just don't act like lead ones.

That's the main reason I've settled on poly-coated FP hardcast slugs in 10mm, at least for backwoods/trail carry and potential defensive use.

4-legged or 2-legged predators, ... doesn't matter. 220gn FP hardcasts at 1225fps. I like those from SNS Casting. The smooth polymer coating allows them to feed slick-as-snot going up the feed ramp, there's no lead build-up in the barrel, ... and they hit like a sledgehammer and penetrate deeply.

Remember, when you're out and about in the boonies, "overpenetration" is a non-issue.

Those copper 190 10mm bullets are way longer than something I'd be comfortable using. Copper is less dense than lead and the more appropriate bullet would probably weigh around 140 to 150 grains. The long bullets are going to severely limit what powder and how much you can use before running into problems.

Lead is the perfect bullet material - cheap, dense, and malleable.

What is the reason ....so they will be legal ammo in California ?

Cutting Edge only makes copper or brass bullets, CNC style.

Copper bullets are quite a bit longer than their lead counterparts. Because of that, they intrude upon case capacity which is why velocity isn't as high as it "should" be. The ACP bullets aren't as long, so I'm thinking they're also lighter weight, or similar weight, but that would be the reason why they didn't penetrate as far as the 10mm did, way less sectional density.
