Grinches & Flying Pigs ( just a crazy thought)
I probably should have saved this for this winter when cabin fever kicks in! However......
Is it possible in our hunt for pointier, higher ogive bullets, with high ballistic coefficients we could be missing something? This is reference to 600 yard shooting/competition. I haven't gotten a chance to test this type of bullets at 1000.
Here it goes! Making a long story short, I wanted to see what kind of results I'd get by making long range bullets on short range bullet dies. I made up a couple of different versions but settled on a 103 gr bullet made on a double radius 7/10 ogive. Compared to a typical long range bullet these are like shooting mini-balls. They have a great deal more bearing surface, a blunt nose and low Ballistic Coefficient. Everything a long range shooter isn't looking for, it's basically a "Flying Pig."
However, at 100 and 200 yards I am getting the type of accuracy I look for in a really good 6PPC. This is shooting the Grinch (Grendel 6.5 case blown out with a 40 degree shoulder) running them 2920 Fps. So far what I'm seeing is a bullet that's easy to tune, highly accurate and appears to lack the ability to throw shots like many of the high BC bullets are so good at!
Really kind of a radical train of thought. I don't know what it is but there is something to it. Perhaps the extra bearing surface helps stabilize the bullet. Maybe it's inherent accuracy of the bullet itself making up for its low ballistic coefficient. I just don't know.
Also I'm not seeing this bullet get kicked around by the wind either. I literally, made these two days before leaving IBS 600 yard Nationals. So it was the first time out with this bullets and the Grinch with an 8 twist barrel. Out of the the 81 shooters or so there were 11 aggs that were better than mine. That's looking at the actual aggs for the 16 record targets. I made the rookie mistake of getting my barrel too hot, and my second group was almost always bigger than my first. But the bullet produced some nice groups (1.190, 1.526, 1.618, 1.988, 1.445) and not bad aggs for the first time out.
Maybe this fits more into the category of "There's more than one way to skin a cat!" Or "How do Bumble Bees fly?" I don't know!
Here are some of the groups I'm talking about.
Those 100 yards 3 shots Groups.
These are 3 shots at 200 yards! Stuck a Pig in the .063 to demonstrate its size.
Nice 600 yard target from the Nationals!
Go Pigs!
Go Grinch!
