In most reviews they shoot many types of ammo and usually only show the best groups.
I remember seeing articles in the 80's G&A where they would show three or four groups and write the ammo down with each group.
I think it was to show that different bullet weights, speeds and designs acted different in every rifle.
In stead it had the opposite effect and people were writting in saying they read the article and they bought the X brand of ammo cause it was the most accurate in the test of the rifle and the groups opened up. The opposite also came true in advertisement.
If Win was the top loading in the month before they had adds in the mags if Rem or Federal was the top it was buying space.
And Swampman is just a Rem fan. No Matter what the question, Remington is his answer. I sometimes wonder if Remington sends him a check for a quarter for every post he makes here talking about Remington.
I think if you showed him a swayed barrel from one of their guns out of the box he would say it was the best thing since sliced bread as you can hide behind a tree and still shoot the deer, and while it does not shoot where the scope points it will still shoot 1/2" groups at a mile.
With that said I have four (4) rifles in 223 rem.
the two bolt actions both shoot very well and I am taking caps off of soda bottles at 100 yards with either.
And I hate to write this as it adds fuel to Swampmans arguments but my 700 SPS with the Reminton UMC 45 grain bulk ammo I can take the caps off soda or water bottles at 200 yards with out a problem. But i think that is more to do with the weight of the rifle and the scope than the make.
The SPS wears a Weaver 6-24X42 scope and the Cz 527 American wears a 3-9X38 weaver.
Oh at 200 yards with the scope at 24X I can still read the whole label on the water bottle but can only see the bottle at 9X.
The SPS is in a Kevlar stock and weighs about 11 pounds with out the bipod and the Cz is under 7 pounds.
I think if the Cz were a 527 varmint in the kevlar stock with the same scope I would have the same results.
The other are an AR with Iron sights and a T/C with a 16.25" carbine barrel and weighs about 4 pounds.
All four have a different use.
