That is funny there... .

I do like to shoot. I shot over a 100 rounds this summer playing with my 30/06 in one sitting? With no silly pads or stuff like that... I also have my own 100 yd range that I use regularly. I have a nice collection just not an M1 variant.
HHhuntitall, you reload? Have you found a bullet they like to eat? Do they chew the brass up as bad as some have mentioned?
Even though it is my dream rifle, it comes at the worst time of the year! But you throw in recent events and I am concerned this may be my last chance at a reasonable price for awhile.
I like what I am hearing though!
:-laf Not sure what you gave for it, but in a few months, you may even make money on it... .
I reload a little. I've had several M1A's, and they all vary, just like any rifles..... I've reloaded for all of them. Typically, they like the 150-180 range of bullets. That area of pressure curve is what they are designed for. With all the excellent powders available for the . 308 today, it's a very good all'round rifle. I prefer the heavier bullets for range and knockdown energy. I've had two that really liked the 180gr Berger's, but they didn't feed very well due to the OAL. Typically, the 168gr Sierra Matchking tends to be the best all around bullet I've used in these rifles. The current Army match loading is eihter the 175gr Sierra Match Kings, formerly named the M118LR, currently switching to the MK316 designation. It's loaded with 42gr IMR4064, Federal Gold Medal Match 210 primers, using the 175gr... . it's a pretty hot round in a small chambered rifle... . Works pretty good with a mil-spec chamber with lots of lead in the throat area... . You'll also see a lot of training/match ammo being used for Match/Sniper rounds, using the 168gr SMK, named the M852, which, IIRC is 44gr Varget with the Federal 210GMMatch... .
I have also used the Berger 210 Hybrids in single shot configuration for match use, with some luck. The barrel twist needs to be 1:10 for that, and sometimes a modified piston valve has to be used to modify the pressure curve... . High pressue loads can be pretty abusive to your bolt and locking lugs... .
As for eating up the brass, that's all about the tuning. For example, sometimes, the locking lugs have sharp corners that need to be "softened" by a good polishing stone or Dremel tool... . Rounding the corners helps keep the brass from getting sharp scratches, as well as the bullet jackets. I've had more than one that would give a "flyer" on rounds picked up from a certain side of the magazine. I've traced it back to severe scratches on the bullet jackets... . I guess I should refer to them as gouges, as they must be deep enough to effect the bullet's integrity, hurting it's cocentricity in flight... . Rounding the sharp corners reduces this, and doesn't hurt the reciever's integrity. Obviously, you don't want to get carried away... .

Still, hot brass is very soft, and if you use optics over the ejection port, the brass is easily dented by hitting the scope, reciever, or anything else hard. Modifying the ejector can help on ejection angle and velocity. Modifications to the gas system can help slow the bolt velocity, effecting ejection speed, therefore ejection force on the brass, as well. And an overly large chamber, as is common on most semi-auto battle rifles, will stretch the brass to it's structural limits. This aids in extraction, but hurts the longetivity of the brass. I've found cutting a semi-match chamber helps the brass' longetivity greatly. It sometimes can cause extraction failures in prolonged periods of fire, but it's a compromise of accuracy vs. reliability... .
All in all, I'd have to say the SOCOM is a good all around rifle. You get the accuracy and range of a good caliber, suitable for most needs, yet the handling characteristics and adapatability of a smaller carbine, combined with a fairly large magazine capacity and excellent reliability. While not exactly simple, they are extremely reliable, and easily serviced... .
And mentioning the magazine capacity brings me to another tuning point... . sometimes, large capacity mags can exert a great deal of pressure on the rounds inserted in the top of the magazine. This pressure has to be overcome to chamber the round, which can result in reliability issues and brass injury. To keep from damaging the brass, you slow the bolt down some... . but there may not be enough inertial energy to extract the next round from the mag... . Sometimes, you load only 15 in a 20rnd mag to keep upward pressure minimal... . Compromise of accuracy vs. reliability... .
