Hey guys
Ive got a 1917 303 Enfield that is being more than a bit difficult to cast for. This is the first one that really is kicking my butt lol.
IF i use a low charge of unique, say 11 to 11.5 grains, accuracy is okay out to 100 yards with a plain base noe 213g bullet pretty much any way i flavor it. Pb, pb check, gator check, any lube etc. Pretty smooth sailing and sub 4 inch groups at 100 yards without trouble and no leading.
Now where things get annoying lol... using a little more oomph I start to get sporadic but notable leading at the muzzle and poor groups, and not seeing a lube star at the muzzle. Imr4227, 5744, and imr 4350 have been used. Ive shot a handful of 1 inch 5 ahot groups at about 125 yards and some clover leafs at 50 yards with the noe 213g .316 GC bullet and 5744 at 21g of powder... but its not consistent. Often it leads and shoots poorly.
A couple thoughts that may help.
same alloy gets used in 308 and 3030 up to 2000fps, works well. Mostly cww, sprinkled with a little tin and range scrap.
Not seeing the lube star at muzzle stands out to me on the long barrel. Using eds red. Also have alox and white label bac and 2500 now that I didn't before. Powder coat seems to help but not fix it 100 pct.
I am having to seat bullets lower in the neck than id like to chamber proper, not sure how secure the GC is. The gc also seem leas secure on the shank than im used to seeing. Some spin etc.
Loaded rounds pulled bullet still measures .316
Have shot good groups with .314 .315 .316 sized bullets, still sporadic lead at muzzle. Throat can take about a .318ish max.
Im kinda leaning towards lube issue and or GC issue... any help is appreciated.
