Bullet slump and accuracy with differentt alloys

When you get those back issues of BPM there's a VERY objective article in one of them concerning alloys, bullet slump and accuracy. I was negligent in not posting a link or at least a brief Synopsis of the author's findings. Any new BPCR shooters ( like me ) will find that article very interesting. I hope you' enjoy those magazines . They were VERY well written and informative.

Please post the issue date/number when you find the article.

Thanks,

Will do Ross, I think it was in the first one on top the stack a Dan Theodore article working with 1 in 20, 1 in 16, Lyman # 2 and harder. but mostly with greasers. bobw

I am still a skeptic that a bullet nose supported by barrel lands and started on coax can ever slump to one side from a trip up the bore. They can how ever bend if seated off center in the throat or when captured either in snow or some other media. I've looked at a lot of snow bullets that were dinged and bent and the land marks looked the same length on opposite sides to me.

Mike, If you can analyze this bullet or anyone on here, please tell me how this bullet got slumped being a snug bore riding PP that has all but 1/8" in the bore.
I have only seen one other long ogive actually worse then this one that was shot with 1/50 alloy with the thousands of undamaged bullets I have studied. Some even are longer than the unfired.

Kurt, that could easily be impact problems not ignition problems. Not saying it is, but it could be.

I'm with Brent on that one.

Brent when I do the tests I make sure that the snow bank has a strait entrance path of the bullet. With this bullet it did not show any sign of hard impact like ice crystals and the snow was fresh not piled. The land cuts were lower on one side then the opposite side this tells me that one side had more contact with the bore.
Like I said I only have seen two with signs of nose slump. Just recently I reclaimed two 5 gallon buckets full of these snow bank bullets I got tired of moving around and most of those ingots are from that collection Again I have no explanation why this bullet has a slanted nose. All I can say if it hit something hard the damaged would have shown up as a flat surface.

I've picked up bullets that have been bent around in a semi-circle from hitting the ground here at home, ( very sandy soil ), some of those have had very minimal impact damage, go figure. Maybe that one in the pic just glanced off some harder packed snow at just the right angle???

I have seen such banana bullets in the berms at Lodi too where is very sandy. They can be undamaged but still bent - more so that could happen inside the barrel.

Kurt, you might look at the rifling marks on the ogive -if it bent in the barrel there should be some indication in the rifling marks along the ogive.

Brent that bullet is now in one of those 10# ingots

When it snows here, it snows. usually it's powder this time of year and it is very soft.

This is what my usual test bank looks like and the shots are straight in.

At the risk of repeating myself, what is all that white stuff????
How do people live in that sort of cold?
