One of my favorite topics--
I like to comment on these things but I came in late and most of my standard suff has already been mentioned by others.
I concur as to use of the .30-30 rather than the handgun calibers. First, it is a good deer rig, far more so than the lower-powered cartridges . I am fully aware of the drawbacks of the rifle rounds for household defense, but with a properly set-up firearm, with which you've practiced, one should seldom miss. Also, the lever action encourages precise shot placment and discourages even a subtle mindset of "spray and pray." And, once again, if you DO have to use it, there's no firearm that is as "grand jury friendly" as the ole deer gun.
One thing I hadn't thought about, though--It is cheaper to shoot the handgun calibers, and FAR cheaper to hand load for them. How about two guns set up identically? A Winchester or Marlin .30-30 in full trim, and ALSO essentially the same carbine in a pistol caliber, set up same way--Same sights, barrel length, spare ammo storage, sling, etc. This allows for the quick drills at short ranges, less recoil, inexpensively and so forth. This is rather like having a Colt Ace .22 or a .22 conversion unit for your 1911 or other combat handgun. (Yeah, I know--almost twice as expnsive. Money's a faco with me, too.)
As to carrying spare ammo, I like having the ammo with the gun. The old timers seemed to always be picking up a bandolier or "shell belt," any time they picked up the rifle. I've been in MANY ranch buildings in which the carbine was racked with the cartridge belt hanging from same peg. Same way with the "gun rack in the pickup truck" in West Texas that seems to amuse the outlanders so much.
I like Speedy's idea of,
"Extra ammo . . . .44 is carried on a belt loop holder converted to a paddle type." Neat! Keep it with the rifle and hang it on your belt any time you take out the gun.
My personal favorte is an elactic butt cuff holding nine or ten rounds--I've had both. It is important to keep track and make sure the loops keep enough tension to hold the cartridges snugly. When they loosen up, I replace the cuff, counting this as part of the cost of doing business. And it would be a simple but more expensive proposition to have one made of leather.
I respectfully disagree with ohen cepel, who wrote,
"You could also opt for a sling with the ammo on it, never used one, but with training it should work."
You can make do wih almost anything, but I feel hanging much ammo from the sling destroys balance of the piece for offhand shooting, unless you take a "hasty sling," and the ammo interfers with that. Also makes the whole package MUCH more bulky to put into a case for vehicle or horseback use.
Sorry to be so long winded. Whatever you choose, best of luck.
