I am surprised that no one has summoned me to this thread. I am probably by far, the biggest user of .303 on this entire forum, and the biggest owner of 303 wildcats, which is a growing collection.
I am happy to say that the .303 cartridge is by far my most favorite of all. That's why it sits in my username and my signature. My father has taught me well on the cartridge, I have at least 8 books dedicated to Lee Enfields and the .303 on my shelf, a entire cabinet dedicated to .303 and .303 wildcat reloading gear, and best of all: 9 Rifles in my safe are either 303s, or 303 based wildcats. I regularly shoot them, and use anything from the hottest loads I can fit to the softest lead-cast bullets. Listed as such:
No. 1 mk 3 Full wood, matching numbers, Lithgow made, good nick. 3-4 inch group at 100.
No. 4 mk 1 T model, Full wood, matching numbers, Canadian Longbranch, Very good nick. Sub moa groups at 100 with telescopic sights.
Pattern 1914, Remington made, Full wood, matching numbers, still great nick for 102 years. 2-inch group at 100 with open sights.
No. 1 mk 3 cut-down, non-matching numbers, made into a make-shift carbine to replicate the No.5. Pretty, but pretty shot-out bore. Average 5 inch group at 100 with open sights.
No. 4 mk 1, 303-25 Wildcat. Made in England, good everything, nice replacement timber, shoots a cloverleaf at 100 yards. Not even sure what kind of inch group it shoots, the holes never get any bigger
.
No. 5 mk 1 Jungle Carbine, 303-22 Wildcat. This rifle is still experimental, but it did shoot 0.9 inch group at 100 yards with slighter hotter than normal loads. Right now it can't hit the side of a barn door!
No. 1 mk 3, Lithgow made, Parker-hale sporterized Lee Enfield, which I have converted to a target rifle. It put a 3 shot group into a size of 2 inches....at 600 yards. That's enough said for it.
P14 Winchester, sniper variant, converted to a sporter. This one is a specialty as it comes in .303 epps, the magnum wildcat variant of this cartridge. Cloverleaf groups.
M17 Sporter, 303-25. This one is another WIP, and is currently having a scope-mount fit to it. Don't worry, I already bought it as a sporter, the only Enfield I am guilty of butchering is the mount for the No. 4 Mk 1 T rifle, which was a half-ass job that needed fixing by me.
I will eventually compile a picture list to go with them, my list is only worthy when I can show the wood and steel that has gotten so much love from me and millions of people across the world.
