New bullet

[Kurt]

I use this bullet in the photo for long range with the 19 twist .44-90 BN. It has put me into third at the MT 1000 and I shot a 41 at the Quigley using this bullet and during practice several times with stiff conditions. I also used this bullet at Lodi one year and I ended up in 4th place with a 450 something using the .44-90 BN 19 twist rifle.
That bullet is swaged using my Corbin swage setup and it's 1.4" long at 500 gr depending on the alloy temper. I had REC clone the bullet used for the 1870's Creedmoor matches Metfort and some of the other's used.

I also have a .44-90 BN with a 16 twist and this bullet does not do as well in it as it does in the 19 twist for some reason. I have not swaged any for the 17 twist Farmer .44-77 yet but I will later this year and use it for the silhouette matches.

With that cup base I need to use a twisted patch tail tugged into the cup to protect the shirt, but the shirt has a function from what I have read in the old books what it was designed for. They mentioned that the thin skirt expanded fast to seal the bore. This makes sense to me and I studied the bases to see what damages they get with twisted tails and just folded under patches and seen just how much the skirts expand under pressure with 1/10 to 1/30 alloys.
If I was to use a bore diameter PP with 1/10 alloy it would be a cup based bullet over a flat based.

There is something about this ogive design that holds the stability better with a longer overall length. Yes it needs a little more elevation than the longer pointer nosed bullets at the 1K but it gets there in fine shape.
