303 brittish

Can any one help with this oldie but goodie cartridge, have a 200 grain mold, bullet design is round nose, and gas checked. Looking for load data I like IMR powder so does my local supply house, so thats why I like it I just am not familiar with many other brands, and cci primers.

Welcome to THR.
Seriously you need to look at purchasing some reloading manuals. I did a quick check of Lyman manuals both std. and cast bullet. They list the following powders to use with lead loads, 700X and SR7625. Do a search of their web site for lloading info.

Try this link. There is excellent infromation on using cast bullets in the .303 rifle cartridge. http://www.303british.com/id37.html

Curator,


Thank you, the information on the attached web page was very helpful

You might also check out the Cast Boolits forums, lots of folks shoot them over there. They are a great bunch of helpful folks also.
