All.
Some here have opinions based on experience and others have impressions gathered from opinion leaders. And, although it's nice to know what the experts are shooting these days, I'd like to know how those here are doing with their preferred rifle. So, perhaps, those with LR experience, that seems to be one of todays venues for M1A's and AR's, can share their own results with chosen rifle, like posting highest score produced with an AR, M1A or M14 in NRA LR Service Rifle Competition, as well as the wind and weather conditions. I also think it would be interesting to know your starting zero, zero used, and corrected zero as recorded in your score book. I still see folks shooting the M1A in LR with great results but I prefer the AR for reasons I mentioned earlier, mostly my confidence in my ability to control it consistently from shot to shot.
Just an anecdotal thought, my first NRA LR tournament was accommodated with a standard M1A. I don't remember the score. I could look it up but I prefer to forget it. I wanted to use the experience to prove to all that they had not yet seen what good shooting was all about. Well, that did not happen. What did happen was my discovery that I did not know anything about what I was doing. I realized this as I observed my target disappear while perfecting my sight picture after firing a few sighters. Later, I realized mirage from my barrel was the instigator of my issue. At any rate, the experience was an eye opener for sure; and, I was hooked. About 3 seasons later I had my HM card, but not from Service Rifle Division, mostly from scores produces with a 308 bolt gun with irons. I've enjoyed the challenge and the realization it's not about the gun. A good shooter can get good results with any gun that's not broken using his desire, discipline, and brain.
