Bama had asked me a question in the sidebar discussion area, and it was starting to get too big for a discussion there so I decided we should get one going in the open forum where everyone can see it.
as many of you know I use a couple of different alloys for higher velocity's in different rifles.
why would I use an alloy of 4% tin and about 6% antimony in one case.
not really 'case' I guess, instance or design would be a better word to use, but we will start with a single case as an example.
lets go with the 308 since it is popular right now, several people have one, and are using it for target and higher velocity shooting.
so why would I then turn around and use an alloy closer to .75-1% tin and 2-2.5% antimony in the same case to achieve the same velocity and accuracy.
[velocity is 2300+ fps and accuracy is under an inch]
I'm gonna let this sit as a question for a while [Ian/Brad no cheating let's see what the others have]
