[QUOTE="HoLeChit, post: 3504541, member: 35036"] I don’t see why not, but that depends on your uses, expectations, and the actual firearm. I can’t find much with my limited search. This is what I did find: [B]22 LR, 22 Mag, 17 Mach 2 are loaded to 24,000 psi max average pressure (MAP) with the Piezo system, crusher is no longer used in rimfire. 17 HMR is loaded to 26,000 psi max average pressure (MAP). Regards Linda OlinCCI/Speer Tech Services[/B]" I also found that 17hm2 has the same peak pressure as 22lr, but a longer burn rate. It’s essentially a 22 stinger case necked down to a .17 projectile. according to Dan lilja: The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has [B]200,000 rounds through it[/B] and the shooter, a competitive small-bore shooter reported that it had just quit shooting. Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy. [/QUOTE]
