On a 40 S&W and a 10MM with long throats like I made mention of in my previous posts how long should the front band be to reduce the skid of the bullets going into the rifling? I know alloy hardness plays into this and plan to run at least 15 BHN (Lyman #2).
Surely reducing the skid should help accuracy it would seem.
I would like to get a 200 grain mold for my 40 S&W and my 10MM with one lube groove and a sturdy plain base band as well.
Would skid affect accuracy with a cast bullet. Cast in these guns is new to me and the long throats surprised me.
Plus I don't want a weight forward bullet either.

I thought surely someone would offer some advice. Maybe nose style, meplat diameter etc. Or if I was even being concerned on something I shouldn't be concerned about.

No one has answered because mainly the answers can only be found by personal experimenting. There are no easy answers. What is it you're trying to accomplish? I assume you're talking about a semi-automatic pistol and the .40 is neither a target round or hunting ground per se. It is already more than the accurate for self-defense. Perhaps you need to explain just what you are trying to accomplish.

Perhaps you need to explain just what you are trying to accomplish. Personal experimenting can be costly. If one is having molds made. I am trying to accomplish getting a good bullet, that is accurate even though it isnt a target round. No use short changing a short changed round even more. Yes I am talking about a semi-auto. Hunting round, why not? I know of two states that the 40 would be legal in and one is where I live not to mention the 10MM. According to Tim Sundles a 40 is not really a slouch. A 10MM loaded to optimum power is better than it is. I was just looking for maybe a pointer on getting a cast bullet that would do well in the 40 and 10MM around 200 grain weight. One that can take the slamming into the rifling without much skid on the front drive band. Maybe not. That was the reason for the question. I could copy the 200 grain bullet Underwood or Buffalo Bore uses I guess. Thanks |
