New P.P mold for 45-70

[bruce moulds]

randy,
4 x 0.001 = 0.004.
if your bore is 0.450, and your paper does not stretch when wrapped, you need a 0.446 bullet.
while you say your paper is 0.1 thick, that sounds too thick.

i would suggest that the brooks bullets is not shooting better than the p.j. bullet due to nose shape.
it is more likely a diameter thing or length thing.
the best nose shape fir your velocity range is elliptical or money.
this is due to a more stable airflow.
baco have a 0.444 and a 0.446 elliptical.
if you want to be really cunning, you can get kal or brooks to make you a bullet that patches to 0.460 where it is finger seated in the case, and also to bore diameter where it goes in the bore.
this will avoid major case neck sizing and improve accuracy.
make the large diameter about 0.150 long and you will get plenty of powder in your cases.
keep safe,
bruce.
