I've had a bunch of 17 Ackley Hornets over the years, semi custom rifles, but I also had a couple of 14" and one 20" Bullberry barrel. Had so much fun with one of the 17AH 14" barrels especially on the Contenders that it was a toss up whether I liked the 17AH or several of the 375JDJ SSK 14" barrel's I had for them. I used the 17AH a lot at Digger Wars where I'd have to stop shooting when ammo ran out on those 10 day shoots despite having thousands of them loaded for each of the shoots (and even though I continually added more ammo for them each year). I usually shot the 17AH ammo until it was gone before switching to one of the other 16-18 long range wildcat rigs I'd also always take along. The 17HMR ended the ammo shortage when it came out and became my go to in place of the 17AH (also helped along when the 17HM2 came out), and without the need to spend countless hours prepping brass and reloading. Last Digger Wars I hosted was with 17's only (rimfires and wildcats), and was probably the most fun of them. A long time friend is happily using my Cooper Classic 17AH as his go to fox rifle in Alaska now days - replaced all his 22 Hornets he'd used for them for years. All the other 17AH's were sold to various people as well as they were all replaced by the six 17 rimfires I bought that did just fine for my types of hunting. Even so, every Contender owner ought to have at least one 17AH in his life time - a very fun, excellent hunting and very addicting lttle cartridge.
