RE: Steve Brooks mold.
I have a Brooks mould in 45 Posted. First use I didn't like the fill and opened up the plate hole a little bit and it straightened right out and made perfect bullets. I felt the pour was too slow and the bigger hole worked.

RE: Steve Brooks mold.
Kurt, Thanks. I am going to try hard for the mid 30's next year.. I hope a heavier bullet will help at the buffalo. I had 5 on it but felt I should have got more.. All were solid holds but just missed due to wind.. I had one hit on it last year.. Next year going for 8!!

Unless your rifle has a 16 twist that new bullet probably will make things worse on the buffalo in the wind.

RE: Steve Brooks mold.
A 560 grain .45 caliber bullet is going to 1.500"+ long even if it is quite blunt. With an 18-twist .45 you are better off, stability wise, to be no longer than 1.440".

If you are shooting one of the longer .45 cartridges and getting 1350 fps or more you can stretch that out some. At 1350 a 1.460" long bullet should be good. If your up around 1400 fps a bit longer is probably OK.

The only real way to know is to try it and not just when the wind is calm and steady. However, if you push the length to twist thing too much your bullet may be only marginally stable and can give you fits if the wind is blowing and especially if it is gusty.

I do well out to 1000 yards with my .45-70 with an 18-twist shooting a 1.435" long bullet at 1297 fps even when the wind is pretty rough.

A marginally stable heavy bullet can not hold up as well as an optimally stable lighter bullet. Once a marginally stable is slapped with a wind gust it can struggle in vain to regain stability and there is no telling where it will go.

It will take more wind to upset a well stabilized lighter (shorter) bullet and its recovery will be quicker.

I have a Brooks grease Groove money bullet that measures 1.497" in length. The nose measures .452" so it requires deep seating. I have not tested it. Good looking mold casts very nice. Tim.
