And recommended loads with IMR 4895 and the 314299 Boolit? I would like to push them as fast as they will go without destroying their accuracy.
I will be trying these for the first time in a No4 MkII. This rifle has a slightly used barrel and I have not slugged it. Rather I just went out and cast a bunch of Lyman 314299's with Alloy #2 and put a gas check on them.
I was disappointed to find that my new Lyman mold does not cast the bullets larger than .313. When I used my cheap Harbor Freight electronic dial calibrator, that thing read .312. However I broke out my Mitutoyo , really expensive, highly calibrated, caliper ,and found that the bullet was in fact coming out at .313. Since I thought the mold would cast .314, I purchased a .314 sizing die. Well at least the grooves got lubricated.
Oh yes, when I weighed lubed, gas checked bullets, they came out at 220 grains!.
I am going to use once fired 303 Greek brass, I neck sized the stuff, and am using WLR primers.
I want to mention that I tried to use my Stoney Point comparator on this brass. Unfortunately the brass had not been segregated by rifle. I have a bunch of 303 Lee Enfields. At least two No 4 MkII, two Long Branch, three Austrialian No 1 MK III’, a Savage, and a No 5. Maybe a couple more that I can’t think of. Hey, when they were $80.00, and had good barrels, I could not help myself. What would you have done? :drinks:
Measuring fired brass, the comparator was all over the map. Some of the fired cases had case shoulders that looked like quarter circles. Others looked 30-06 ish. Again the measurements were all over the map. I tried my best guess at neck sizing according to the average case. Some these the case heads had been blown out so large that the sized case looks like a belted magnum. I can say with certitude that the British did not standardize on chamber reamers.
I am going to shoot this stuff offhand at my 100 yard gong target. If it shoots within 2 MOA at that distance I will be happier than a pig in clover.
I am going to shoot up a couple of pounds of IMR 4895 and then try AA5744. I gave AA5744 a try in the 45/70 and with cast bullets in the 30-06 and I think it works just great.
