Winchester 40 gr. Truncated Cone HP subsonics have great terminal ballistics, and unlike the CCI HP subsonics, they feed well in match chambers. They don't shoot as well as the more expensive coated HP subsonics though (which lack in terminal ballistics). However, I noticed that the first group after shooting coated match was always nice and small.
So, I took a box of the Win. ammo and coated half the rounds in it with Lee Liquid Alox. I tested on a target 45 yards away. I first fired 10 bare rounds off paper, then printed three 5 round groups (top left). After that, I fired 10 coated rounds off paper, then printed three 5 round groups. Scope adjustments were made on the second row of dots. Rifle was a Sako Quad with a Lilja barrel. It was shot free recoil, pinching the trigger and watching the wind flags carefully.
I'm surprised how much the Alox shrunk the groups (by ~0.2"). It was pretty quick and easy to do, I just brushed it on with a small brush and put the rounds back in the carrier to dry. Careful not to get any on the brass or you'll get FTEs. They extracted fine if I wiped the Alox off the cases though.
