I don't shoot highpower silhouette, but I do have a few hard kicker rifles. I've tried all the brands you mentioned and a few more. None comes close to Limbsaver. I just custom fit one to my lightweight Knight muzzleloader this past year, and now I can practice all day long with heavy charges of powder and those 460-grain No Excuses bullets without thinking about recoil. I put one on my lightweight .270 Win that I use for deer and that thing's nothing now, even with my hot handloads.
