My "unbiased" Opinion
I own several rifles, one of which is an M14 Platform - a Poly M305 in 308.
My other rifles are a Mini-14, Remy Varminter (.223), Vanguard in .243, Browning BAR (30-06). Had a Browning BLR (30-06) which I gave to son and a Sako Hunter (vintage '82). The mini-14 is a plain 'ol Ranch (vintage 2010) after getting rid of my target mini.
I became interested in the M14 as a result of having too much fun and generally good accuracy. I reload all my cartridges.
In dealing with the M14, from sandbags, it will shoot hornady pills on average at about 1" at 100 yards with ideal conditions and a steady eyeball. I have fluked off better groupings, but I also have had worst too. I resize my cases fully and leave a .005" to reduce excessive case fatigue. I have not ever had a case seperate (touch wood) and my recipes are somewhere in these postings. Since working up my loads, I have not really experimented to strive for anything better, because I am satisfied with a relatively cheap budget.
I bought my M14 for fun, but now use for hunting as well. It is heavy (same with my Remy) to carry, as opposed to my Browning or Weatherby. The Browning loves Nosler 165's and is glassed (average 3/4" to 1" groups - sandbaggged). I actually prefer the versatility of the M14 due to the open sights, and the fact that the rifle is a workhorse and designed to be bumped and bruised a bit. Same goes for my mini-14, but it is not as accurate to 300 yards for 'yotes. For that (and gophers) I use my Remy, as it is a supurb tack driver to 300 yards.
My Browning is much more finickety (especially the scope) to some of the abuses of hunting but it is a very fine tuned instrument.
My Vanguard is a deer rifle and long range 'yote gun, depending on my mood, but is more expensive to reload. It is also a very accurate gun shooting at about 3/4" MOA at 100 yards with 80 gr Noslers.
I firmly believe, based on the opinions of their owners that a well tuned M1A will shoot every bit as good as mine, or perhaps better, but I could really care less, as I am not into it for the bragging rights.
If I had to walk all day, I would use my Browning. Pushing bush, I would be with my M14, hands down.
To summarize, the rifle did not cost me a fortune and with a little tuning (thanks to Hungry's clinic) and a good maintenance/cleaning regime, it sounds like my 'ol M305 is plotting holes in paper the same as a loaded M1A. In the end, does it really matter? If folks want to get all uppity for bragging rights as to who's is better then count me out as that kind of discussion is a waste of time.
My M14 sees more use than the rest of my rifles, with the exception of the Remy, because it is very reliable, shoots straight and is a workhorse all the time. It is not the prettiest rifle around but it is perfect for the tasks I use it for, but it is not so well suited for gophers and 'yotes as the ballistics are far from perfect in my circumstances. It is great for Bear! (see previous posts)
Specific to the M1A or M305, you will do well with either. From what I have read, I suspect the loaded M1A (out of the box) will be tighter and perform better at the range than the M305, but will easily cost 3 or 4x that of a M305. Tuning my M305 cost me about $300 (which included Hungry's fee, gas and lodging in Calgary, a better guide rod and grease).Headspace gauges will also set you back $200 if you subscribe to the headspace issues relating to the M1A or M305.
After all the bills are added up...to the paper 100 yards downrange I am shooting the same gun, but at just over half the price.
