Cheers Goldie.
I’ve just ordered a mould from CBE (and a set of Simplex Master dies as my Super Simplex dies are no good without a press.....not sure where that went) which
goes .321 I reckon(?). Also have a couple of hundred of the HRBC 128gr RN’s you’re using. We shoot a scaled back silhouette match at my local pistol club and this info will be of great assistance in getting my Cadet knocking those pesky little turkeys over!!
Just on the .303 situation.....I reckon you’re on the right track. The best shooting cast proje I have for .303 is the old Lyman 314299 casts at 192gr with range trash. .314 (seen worn examples using .316.....really nice stuff using .312).
Cheers again and good luck with the .303!!
Keep calm......and hold centre of mass.

6 shots at 25m in the bull. 1 shot I held off at 4o’clock as I couldn’t see previous shots and one a mate shot at 2....colour me pleased!

Quick update!
Great advice man. Put 20 together settling on 4.8gr AP70N in the slightly long Bertram cases and.....load development over! (Chroni average of 1,260fps....so the sights should regulate nicely too)
Cheers again!

That's a great result Tank. I have also found the load to be correct for the 2nd Pattern sights also. I'm only shooting at less than 100m anyway, and with only two graduations of 50 and 100 yards on the sights, there is not a whole lot of granularity available; regardless, the sight marks align as expected to whatever range I'm shooting. Good luck shooting your Cadet in those club competitions.
