Re: 2 questions: Ruger Express and caliber choice
I have had a few Ruger #1 rifles and none of them shot great. Even my heavy varmint models didn't shoot better than 1 inch or so. The problem is usually found in the two piece stock and hanger set-up.
There are a few smiths who specialize in accurizing the #1's, so if you are not satisfied with the accuracy, there are things that can be done to improve it.
The idea of having a 7mm mag with open site seems a bit odd to me. The mags really shine when shooting at longer ranges and that is something rarely done with open sights.
Personally, I prefer the clean lines of a barrel without sights, especially if it wears a scope. But if you like the sights then by all means make the trade.
I think the 300 mags would have a slight edge on the 7's when your talking about shooting moose.
Just my 2 cents - VH
