Moose Old Style problem

[William Schoenfeld, 1386]

I have a 575450 OS from Moose Moulds that I am having a problem with finding the proper load. Any help on this would be appreciated.

Dutch,

I shoot 40 grains of GOEX 3F in my two band Springfield (Whitacre barrel) with the Moose 575450 OS and it works very well.

I have a rapine 580460OS (basically the same just a little heavier b/c it's fatter) that does great with 48 gr of 3f.

Do your other bullets work OK? Check the muzzle. My musket needed to be crowned and it was difficult to see even under magnification.

Who made the barrel?

[William Schoenfeld, 1386]

The bullet works in other guns Lou and the barrel is only 2 years old which I had from Bobby Hoyt. I have a Rapine old style - little heavier and I use 44 grains of 3 F Goex in it and no problems. This is the only bullet that I have had problems with and I have tried it in 5 different barrels. Go figure! Thank you all for your replies.

i assume you tried lubing the base vs. not? I have noticed that this bullet is a little low on the lube capacity in the grooves, and it fouls harder and faster than the others i use... which is why I use it for 100 yards only.

[William Schoenfeld, 1386]

Jonk I use Lem's lube on it and I have no problems with it in other barrels when using Rapine old style. For this particular bullet I am having problems with it and it has good lube on it - fills out perfectly.

If you are filling the groove/grooves the bullet can not work as per the design. The grooves are required to compress upon themselves. If they are full of grease they can't compress, thus a group that resembles a pattern rather than a group.
