Hello I was just wondering if anyone uses the M1A rifle for long range hunting ? I was just concerned about the remaining energy levels at greater distances and thereby the ethicality of using the M1A at greater distances. Thanks in advance for all thoughts, opinions, and answers.
Several years ago I had a very nice match grade M1A. They are phenomenal rifles but not without some flaws. One of which is just mounting a scope on them. There are several very nice scope mounts, and the nice ones usually work. I say usually because I spoke to a Navy Armourer (and you can likely guess if he was a Navy Armourer putting scope mounts on M14s who he worked with ) he told me that they finally started welding the scope mounts to the rifles, and occasionally that didn't work, and welds would break. So problem 1 is finding a solid scope mount, then testing it enough to trust it..
The next issue I had was it's a 7.62x51. Not sure about the newest commercial M1A's but I know you may have to be careful what you feed it. The gas system can be hurt by some modern loads. Like I said that may be different on yours, but I wouldn't assume it until you make sure. Even if you can shoot any ammo, it is still a .308. Perfectly capable hunting round, but not a "great" long range hunting round in many people's opinions, mine included. Long range to me being beyond 600.
All this being said I love the M1 Garand and all the rifles in its lineage, lots of people have done a lot of really cool things with them, including take game at long range. For myself I ended up selling mine to get a true precision rifle (which i sadly ended up selling not too long after) Making the M1a into a precision scoped rifle was just more of a project than I wanted to get into. If you decide to do so, I wish you the best of luck and can't wait to see your results.
For me it came down to goals, did I want a long range M1a, or did I want a long range precision hunting rifle? Either is fine, but one is much easier, less frustrating and possibly cheaper to get. At the time I had a lot to learn about shooting long range (still do) and didn't want to also have to learn how to make an M1a adequate for the task. I hope this makes sense, and may be helpful.
In my opinion, which is only worth what you paid for it, the M1A is a great military rifle, and can make an excellent military sniper rifle. Even if I had a nice reliable one, I would likely pick something else for long range hunting.
