Article: 11:8 Rumor has it that restrictions on ordering ammuntion without a license will be removed this month. Anyone will be able to receive shipments of ammo without a dealer's license. Am I misinformed? Could this be true? Woody

Article: 11:9 This weekend I had the opportunity to examine and shoot a friend's SKS semi-auto rifle. It's made in China and shoots 7.62x39 ammo. Although I thought it a little heavy for the cartridge it was very pleasant and fun to shoot. No jams or mechanical failures. Shooting was all offhand at informal targets (cans). My questions are: Has anyone seen/used one before? What is your impression of the quality/reliability of the weapon? Since we did no accuracy tests, What kind of groups can one expect at 100 yards from a rest? Are there scope mounts available for them? Is the semi-auto version of the AK-47 (AKS ?) that much better? Which would you buy given the choice of SKS or AKS. Is the AKS worth twice the price of the SKS? Any body have reloading data for the 7.62x39 round? I understand that some of the brass is not reloadable by our primer standards. Which brands are reloadable? Thanks for any help. Woody

Article: 1:16 [ Hey, Woody, what's a .47-70?? Are you sure you don't have a .45-70?

This sounds possible, although I haven't tested the same conditions. I have noticed that when I shoot bullets at different velocities out my .47-70 I will get different points of impact. 400 grain cast bullet at 1200FPS will strike 8-10" HIGHER than a 350 grain jacketed bullet at 2200FPS. This, I am told, is due to barrel time. The instant the powder charge is ignited the barrel starts recoiling back and the muzzle up. It would make sense that the longer the bullet stayed in the barrel (due to lower velocity) the more time the barrel would have to redirect the bullet's path.
