I just put a Green Mt. bull barrel on my 10/22 build. I was wondering what ammunition people have gotten the most accuracy and reliability out of one of these barrels.
Trying to tell someone else how their new barrel, of any make, will shoot with specific brands of ammo is only slightly less complicated than telling them how their wife will react when she finds out about the fact you bought another gun and barrel. Put it this way: You'll be the FIRST to know how your gun shoots each brand/lot of ammo.
Well, you have to start with what you have. That's for sure.
Let me put a number out there 1116 fps. That's the speed of sound. If you can shoot at distances and velocities that don't allow your bullet to drop below the speed of sound, or never exceed the speed of sound, you'll generally get better groups.
If you're just going for minute of squirrel at various distances, shooting offhand, that's a different exercise than trying to make as small a group as possible at known distances.
I'd start with what you've got of course, you might get lucky out of the gate, but the ability to access many different offerings is important to squeezing the most out of your rifle.
You might want to carry a little extra .22 with you to the range. You might find someone willing to trade you a couple of rounds if they understand you're trying to find what shoots best.
Id trade you even for a couple of other brands and styles if I ran into you at a range.
I'm sure others would too.
Wolf match target. SK std velocity. CCI Green tag or SV. RWS subsonic hp. Winchester 42 grain s/s hp. Lapua, Eley. New Norma stuff. Try Champion shooters supply.
