Ballistic Coefficient vs. Accuracy?

[Kurt]

I feel it's the length ratio between the elliptical ogive and the shank that throws the balance out the window and not so much as the diameter of the nose hemi. Keeping the elliptical radius short you can get away with it.

I could see Dan with his HP match shooting background trying to change the black powder bullet profiles close to the HP bullets and this is where his MB designs started.

Brents prolate bullet has the ogive similar to a football and he does well with it. I have one of his prolate moulds I got from him and it was on the long side and I ended up shortening it twice and it does well but it falls short at extended range at the gong shoots where high winds are common so I retired it.
personally I think if he would have stayed with the bullet he used on his web site and did away with the cup base and shortened it to 1.400 or 1.425" it would have been a better choice for the .45 cal 18 ROT. That bullet was more inline to the old long range bullets.
I personally like a bullet with a Tangent ogive radius length of around 2.4" over the longer elliptical and a ball hemi of .26", maybe a smidge larger.
This swaged bullet I use a lot and I swage it with a cup or flat base.
It's a copy I had Rich Corbin make of a Metford.
Hey there is no end if one really has an interest in the old shooting ways. I started in the early 50's looking for a better way but I end up back where I started. It worked good for the ODG's and it still does for me.
