I am starting to look at a new rifle, and am currently looking at a Blaser r93 7x57. I have a couple of questions which I hope some of you may be able to answer/ give your opinions.
1) with the rail mount system, is there much difference in terms of height of the scope? I understand this will vary due to size of the objective lense, but essentially my question is with a given scope, will it sit lower on a rail or standard mounts. I like the idea of the rail, but there are more scopes out there available as standard.
2) if I was to buy a .243 barrel in the future, would I need a new bolt head or magazine insert?
3) aside from the fact Blaser don't make 7x57 barrels for the R8, is there any reason why I should be looking at an R8 over the R93 if I am willing to look at a different calibre?
