Sorry Gents I have been away from the shop and unable to get the mould info as asked. My Armi Sport feeding problems have come down to bullet nose shape. See the attached pic. On the left is a 200gr. RNFP common casting that works well in revolvers and vertical lift carrier rifles; Henry, 1866 and 1873. The short (nose to crimp groove) distance binds during lever cycling in my Spencer carbine.
After several years of frustration, not to mention disassembly of the action parts and polishing, it seems this binding issue is caused by the magazine retainer bar dropping so low into the receiver and that it binds-up on the bullet nose of the next round out of the magazine.
I found a cast bullet from Budget Bullet,
www.bulletmen.com that worked better. (center pic) It was still 'jiggy' on the first couple of rounds out of the magazine. It is from an old Lyman .44-40 (.427) mould and has a longer more gentle ogive with a thin driving band. Distance from nose to crimp groove is longer than the standard RNFP. In fact it is just long enough not to clear the mag tube in Henry,'66 and '73's and does not to feed properly but it worked more better in my Spencer. Budget Bullet is no longer around and I do not have the Lyman bullet mould number that they used.
On to pic #3 on the far right. This from mould #43-222F made by
www.accuratemolds.com and as I ordered it casts .428" diameter bullets before sizing and lubing to .427". Distance from nose to crimp groove matches the Budget Bullet but has an even more gentle ogive radius and also a smaller meplat diameter. IT WORKS!!
I was able to run 7 dummy rounds from the magazine through the action with absolutely no binding at all. Feeding is smooth and reliable. I loaded 100 rounds and will be shooting them at tomorrows monthly match. Back with a report later.
Accurate Molds offers quite the selection. If you're looking for a .45 caliber try matching length and nose radius that I used in my .44 Russian. Their site has excellent line drawings with dimensions for each mould they make. Slug your bore and order .001" over your barrel groove diameter for cast lead bullets.
