You'll love shooting the Enfield. Back in 1994, I picked up this unissued
Enfield, mummy wrapped in the Cosmoline, along with an unissued matching bayonet for $160.00 from a local dealer here in Phoenix, that had come into a bunch of them that the Irish Republican Army had sold off. They had been in storage for almost 50 years. I should have bought 10 of them. It took a bit to clean it all up, but after I did the rifle was in perfect, unissued condition. I've since turned down $650.00 for it because I wouldn't be able to replace it.
The Enfield action is very smooth, and the gun very accurate with it's as issued open sights. The only "downside" to the Enfield action is it cocks on opening, and the action locks up at the rear of the bolt. This can cause the cases to stretch a bit more than normal, which reduces case life with higher pressure loads. I've found if I keep pressures in the mid range, case life is much longer. The .303 British round is close to the power level of the .308, and slightly above the .30-40 Krag round. Just remember if you reload it takes .311 diameter bullets, not .308.
