I’m looking to see what ammo others are running for 100 yards in there 457 MTR I’ve been using SK RED,SK Orange,Federal gold std,CCI MM so far none of these have given me any consistent results.im using accu-tac bipod with a barrier on table,bags or ears on rear,Athlon 6X24X50 have action torqued at 20in/lb .AT 50 yards its getting consistent 1/2 groups down to one ragged hole with 5 shots ,at 100 she really opens up 1 1/2 to 2 inches and greater at times.
You can't just try a box of each and then declare that each ammo performs a certain way. The performance of rimfire ammo varies as much from lot to lot within the same ammo line as it does from one type of ammo to another.
You need to determine how much you want to spend on ammo. Then get a few boxes of different lots of ammo in that price range. Many shoot Eley Match in the black box.
The Match ammo is the same as others in the vertical line. Same machines that produce Team are producing Match. The only difference is that when each lot is tested, the lots that perform less consistently are labeled Team and those that perform more consistently are labeled match. You are paying for consistency.
Its the same with SK. Standard plus is the same as long range Match. Long range Match costs more because its more consistent.
When I choose lots to try, I usually go by velocity. My rifle tends to favors ammo rated at about 1050 per second.
These days, Ive been using SK Long range Match as my good ammo and standard plus as my practice ammo. I use SK semi auto for informal shooting.
