Couger,
Thanks for the questions. I limited it to the pre-64 Winchester because it has all of the strengths and benefits of a 98 Mauser, yet it comes a featherweight package.
While I know that many folks like the Ishapore, I think it is a very poor bet. First, it is a copy of the old Enfield No. 1, not the more modern Enfield No. 4. Crummy iron sights, no receiver sights, and like all Enfields, it will grow headspace every time you shoot it. There is a reason that Britain made four extra sizes of bolt heads for the Enfield. As you shoot the rifle over an extended period, you have to replace the bolt head with the next size up so it won't blow up. Today, it is very very tough to find a No. 2 size bolt head to replace a worn out No. 1 size. I haven't seen No. 3s in years, and I've never seen a No. 4. So, where are you gonna get these bolt heads when your survival gun starts to wear out?
Also, the majority of Ishapores I have seen have nagging feeding problems with the magazines. You can google it and read all of the complaints. Most of them are things like, "My rifle will feed the first 4 rounds, but always jams on the 5th."
I guess I am surprised that most of the responders so far have said the Win. 70 would be better than the Remington 7600. Kinda the opposite of what I expected. Though the 7600 is a little slower to reload, I think that in any armed confrontation the first five rounds fired would be the most critical, and the the 7600 can fire these at lightening speed.
Best, Mannyrock
