303 British Bullet tips.

[Therion]

It was suggested to salvage bullets and powder from mil surp 7.62 x 39. What about using bullets and powder from 7.62 x 54R? I believe that those bullets are roughly 170 grain. I had seen a suggestion to do this, and as I recall, a recommendation to use the powder, but hold back about 4 or 5 grains (I am guessing that would be of the order of 10% of the original load). Has anyone done this?? Comments??

Thanks in advance!

When you get the rifle(which one?), you'll need to check the headspace first, then slug the barrel. The barrels can measure from .311" to .315" and still be considered ok. Over .315" is shot out for jacketed bullets. Lyman makes a .314" diameter mold for use with gas checks. Runs $90.15US
Issue is that the only jacketed bullets made, assuming you can find any, are .311" or .312" diameter. Hornady makes .312" and .3105". Speer and Sierra use .311". Not much good in a .313" barrel. Only an accuracy thing though. Not unsafe.
There's 200 grain data on .303british.com. Close enough for a 205.
