I might actually buy one of the top ammunition in that post and the bottom ones so I can actually see the difference for my self and learn what to look out for
Cheers joker
Not so fast Joker... you need to be confused a bit more!
While "better" more expensive ammo is usually made to higher specs and tolerances, that is no guarantee that it will be the best shooter in your rifle.
The minute vagaries of rifle manufacture, variances in tolerances, steels used etc, etc; particularly from make to make but even from batch to batch with in one make, or even rifle to rifle; means that each rifle has it's own "harmonic signature" (so to speak). This means that you might find one cheap brand of ammo that shoots really well and that's the only thing that will give you GOOD results, no matter how much you spend on "BETTER" ammo. You may find that your rifle "likes" 3 or 4 different rounds but prefers one. You may find, like my wife's 22lr that one sub and one high velocity shoot the same windage but about an inch+ difference in elevation at 50m. You might find that all the ammo your rifle shoots (or groups) well, all shoot 3" apart both left and right and high and low; or, you might find a few that all group with in 1" of each other, center to center.
The only way to find out is to try different ammo and concentrate on shooting consistently!
My t-bolt shoots a cheapo brand ok, like just under an inch at 50m (they're better when i 'do some work' on them), shoots Win PP42 quite well (closer to 1/2") and really likes CCI Velocitor, ie: typically under 1/2" and occasionally down to 1/4" at 50M.
I've run about a dozen different rounds through it to find those. Typically, between ammo types, i patch the barrel dry, shoot 10 rounds to foul the barrel with the new ammo, then do a 5 round group at 25m. Anything that doesn't group under or on 1/2" at 25, i put aside. Then i repeat the process at 50m. Patch, foul but then do 3 x 5shot groups and pick the best from there.
Also helps to learn your rifle and refine shooting technique if you're new to it or have a new rifle.
Good luck... hope you find a cheapy that shoots well!
