Browning 1885 BPCR

[Don McDowell]

The Browning throat is short compared to the Pedersoli. I had to increase the compression in order to seat the bullet deep enough to chamber, just touching the rifling.

Also, the Browning measures .460 groove diameter. The Pedersoli measures .458 groove diameter.

Odd the groove on the BPCR is that large. But you have to go with what you have so get a mould that drops a bullet at .460. Still compressing 70 gr. of 2f should not be a problem and seating to the driving band works rather well in most rifles.
2 different rifles using different loads is pretty common, if you are trying to get the most out of each.
