I can't stress enough how much I love the .303 Brit. I was able to buy ammo during the Obama ammo crisis, while everyone was stripping all the .223/5.56mm off the shelves.
There's a community of Enfield fans out there, posting information on homemade scope mounts for Enfields, handloading the .303, casting .303 bullets, loading chargers correctly, etc. The Enfields are a proven system that works very, very well. I think I got my chargers -- NOT stripper clips -- from Sarco.
~ Some years ago, I picked up a folding .410 by Yildiz, which Academy was almost giving away.
It's a single shot that weighs about 3 pounds -- essentially a pistol in weight and handling qualities. It's the one shotgun I can operate one-handed without much trouble. It's hammerless, with a hook on the underside of the receiver to open the gun.
I cut the barrel down to 19" and installed a new bead (bead and tap and drill bit from Midway). The trick, by the way, is tie a thread to the original bead and run it down the barrel to the breach. I then used it to make my mark for drilling the new bead
before cutting and chamfering the barrel. It now folds to fit in a day pack and has a cylinder bore. Fun gun that's so light that it feels almost weightless in my hands. That lack of weight means there's some recoil with the heavier shells.
A .410 single shot is simply great to have around. It's the most cost-effective shotgun shell to reload for and uses very little powder and shot. Short shells made from .303 or .45 Colt or .454 Casull brass work just fine.
As long as you use the .410 like a rifle, rather than a shotgun for wingshooting, it's good for squirrels and other small game or pests. If you have a 20 ga. single shot or double barrel, a
chamber adapter to use .410 shells is inexpensive and surprisingly effective. It turns your 20 ga. into a multi-caliber firearm and drops the recoil down to almost nothing.
~ The .303 Brit, .45 Colt and .410 all have the same size case head and rim. This can help simplify your reloading. I do not have a factory-made setup for .410. Instead, I made some tools and bought a roll crimper that fits in a handheld drill. My only handload so far in the .410 is a subsonic slug using backwards .41 Mag. cast bullets glued into wads, kinda like a badminton birdie. They're accurate, surprisingly quiet at the range, and have almost no recoil in a Mossberg 500 pump, but I would
not want to be hit with one. This is a slug round for your teenage daughter or your grandmother who's recoil-shy. Lots of fun!
I got into .410 after reading
Locusts on the Horizon, which has some excerpts online for free, including this gem:
Homemade .410 Reloading KitThe Lee Classic Loaders in .410 are hard to find and expensive, so this article was a huge help to me, as was the rest of the book.
