Dear All

Thank you for your advice and insights so far, I have subsequently been able to find and secure three die sets for both .450 BPE 3 1/4 and .500x2.5" (which happens to be Sharps 50-90 so guessing James Beattie copied this Buffalo calibre, chamber cast clarified).

My next questions feel 'naive' but searching the internet does not give away much!
1. Does anyone paper patch their .450 BPE bullets? If so have you any tips (I have the Paper Patch paperback)
2. Can you/should you (does anyone?) shoot FMJ ammunition in a BPE rifle using BP?

All help welcomed.

Meanwhile will get pics of the James Beattie on here, it really is stunning and came with all teh original ancillaries including bullet mould, sling etc. Unbelievable sleeper.

Best wishes

Let he who casts the first stone - be accurate.
If he cannot be accurate, he should practice first.
