Ok so I have been loadingcast for my 1903a3,mosin 762x54r with good results and very little issues, heck I dont even have any leading issues...
Now moving on to 303 brit.... I been loading FMJ with out issue with the lee deluxe set using the neck size die... Moving on to cast..
Bullet is the 314299 as dropped is just a touch over .314 my rifle slugged at .3128ish few slugs came in at 313.... so I figure the .314 would do well as dropped.
I neck sized as before for FMJ... I found that the cast boolit can easily be moved in and out of the case.... I tried adjusting the die a tad more but The OD of the neck doesnt get any smaller than .335 (currently dont have a way to measure ID)
The boolit feels snug when seating but When I check the boolit can be easily spun and moved in and out with just fingers.
I plan on at least using the 303 for 100 yds with 2400 or maybe with
H4895 but cant see getting a good ignition with bullet this loose? I also see the boolits setting back if I mag load?
What am I missing, ohh and I ordered a 303 FCD and recieved a 762x54... thats ok as I have the 54r dies to add it to?
I flare with a universal flare die, I think its lyman..
