My rack is graced with two very fine .303s. One is a 1914 #1 Mk III with its original barrel, beautifully custom-built to resemble the classic Lee-Speed sporters, and mounting a vintage Lyman aperture sight. The other is a '55 Fazakerley #4 Mk2 in new condition with a Parker-Hale 5C match sight.
I loaded fourteen different recipes, ten rounds each, and fired five of each recipe from each rifle at fifty yards. Loads used 2400, IMR 4198 (with dacron fill), and IMR 4831.
The bullet works! In water-dropped WW it weighs 208 grains. I sized at .314" and lubed with Lar's BAC.
Since I was just sort of "feeling out" the bullet, I was pleased to see a one-inch group from the Mk III with 4831, and a sub-1" group (but not by much) from the #4 with 4198. There seemed to be considerable vertical stringing going on, but much of that is likely due to my "vintage" eyeballs and the resultant difficulty with iron sights. Both the above groups came at a velocity of +/- 1700 fps. 2400 failed to give much in the way of accuracy.
These early results are better than most of my groups to date with the Lyman 314299, so I have expectations for even better performance in the future. Thanks to NOE for filling this gap.
