tag to answer at home with my logbook. did a comparison test including the silver tips last week in my varminter.
ETA:
Ok, the 50 gr. Ballistic SilverTip (winchester supreme) went 7/8" for 5 rounds at 100 yds. from my 24" 1 in 9 varminter. That was the largest of four 5 round groups. It was the third best ammo I tested back to back. The best was the 50 gr. Speer TNT (federal premium) whose largest 5 round group was 5/8". Here is how the 9 that I tested ranked:
Federal Premium 50gr. Speer TNT 5/8"
Federal Premium 55gr. Nosler Ballistic tip 3/4"
Winchester Supreme 50gr. Ballistic SilverTip 7/8"
Winchester SuperX 53gr Hollow Point 1"
Winchester Supreme 69gr HPBTM 1"
Winchester SuperX PSP 1 1/8"
Federal Premium Trophy Bonded Bear Claw 1 3/8"
Winchester Supreme 40gr Sierra Varminter HP 1 1/2"
Winchester Q3131A 1 5/8"
Each of the various measurements represents the largest 5 round group of four groups fired, from the bench, with a bipod. There was a 5 mph crosswind, at 85F, 44% RH.
Every rifle I own has a definite preference for one particular brand, but this varminter went 1 MOA or better with 5 brands, and under 1.75 MOA with all 9, so I am pleased. Not too bad for an out-of-the-box BM.
Hope this helped. I will try the TAP as soon as I can get some.
