Re: Just started Casting - Learning a lot


The 245gr. .429", so called Thompson bullet - the gas checked version of Keith's bullet is a good one for lever guns.

WW- dropped quickly into water will attain anywhere from about 24 brinel to 32 brinel - in other workds, varied, depending on their exact temperature when they hit the water.

Pure Linotpye runs Brinel 22 and is very brittle when cast straight, due to it's very high antimony content. Mixing it 75%/25% with pure lead should give an alloy that will allow an easy 2,100fps in the .35 rifle and produce a slightly more ductile alloy.

Mixing 75% (hard) WW with 25% Linotype should give an alloy that will take just about any velocity in the .35 yet the noses should expand slightly and sluff off like a Nosler bullet in game.

Lyman manuals usually give the formula for Brinel 16 - ie: Lyman's #2 alloy - a mix of pure lead, lino and tin. This is the alloy Lyman moulds are supposed to labeled as to weight.
