Question
Mike:
Is this AR15 a gas gun or space gun IE: AR15 working as a bolt action single shot?
I have never hear of someone shooting an AR-15 gas gun as a Palma rifle.
Eventhough I think a 223 can be shot in a Palma match the palma guns I am familiar with are shooting 308 (SAAMI or CIP spec) or 7.62 Nato with 155 to 156 grain bullets. These rifle use matalic or single lens metalic sights. (no scopes) I beleive German Salizar and some others were trying to compete with .223 rifls in the Palma class. In my opinion in short and medium range the .223 can hold it's own. I don't beleive it can compete on the same playing field with a 308 at 800, 900, and 1000 yards.
There are chapters of rules in the NRA and Palma (Full bore rule books).
There is an extreme difference in short range shooting and long range shooting equipment. There is an extreme difference in Service Rifle, Match rifle, and Palma, and Long Range Prone.
Your post has me guessing. I know short range shooters who shoot their rifles 5000 rounds without any competetive problems. Usually at the last 500-1000 rounds they see a loss is vertical. I know of very few High Master Long Range shoters who shoot their 308 rifles more than 3000-3500 rounds even with a set back at 2200-2400 rounds. Those shooting Longrange prone with 6.5 X .284 or other hotter cartridges are lucky to get 1600 round of barrel life.
The Palma rifles that I am familair with, to be competetive have to hold .5moa. I have not seen any barrels with 5000 rounds on them that I would take the time and expense to set back.
