Home Forums Hunting & Shooting BPCR 45 cal Gould bullet.

Spent an hour this afternoon carefully polishing the mold cavities via the generic Dremel which I use for the tough jobs. Cleaned it up,gave it a good carbon dousing and ran another batch of 30:1. Bullet Weight and diameter still constant..Kept the nose pin hot beside the pot this session which made a much nicer HP..

An update FWIW..The new mold throws a smaller dia bullet than I'd care to entertain via smokeless or BP substitute.They mike an average .456 but bump up OK with BP.First load testing shows a preference for 85 grs Of 2F out of the 45/110.Haven't had the chrono out yet but will on the next go round.Accuracy is better at 100yds than I anticipated if I do my part.The '86 Winchester 45/90 is up next for a go.

Contacted Lyman they said send it back with a few bullets..not holding my breath whether they'll replace it and doubt a new mold is much better,,we'll see.

They will bump up just fine with smokeless or the subs, both run more pressure than bp, and the pressure is what causes the bullet to "bump" up..

We're going to find out next week via BH-209 loads for the 45/90 lever gun..The mold is inbound to Lyman for their inspection and or replacement.

Unfortunately undersized moulds seems to be a regular thing with Lyman. I hope it works out for you.

In case you are not aware over at the Castboolits site there have been a number of group buys for HP moulds in all sorts of calibers, including 45 and 50 cal. There have even been 45 cal Gould style in plain base and GC styles. The only downside is that timing is out of your hands. There are also specialists who can alter an existing mould to accept a HP pin (depending on the mould's design).

When making HP bullets I found it easier to make them without so many rejects by bumping up the casting temp and ladle pouring.
