I’m a brand new to air gun shooter but not new to bench rest. I bought a king in .30 and immediately converted it to 22 with a superior liner. I have tuned it up with 18.13 gr jsb and it shoots wonderful in low wind conditions. I plan to attend a bench match and need advice on Pellets at 100 yards. I was hoping to not buy and try every damn thing under the sun. Thanks in advance
