Springfields ratings on their rifles indicate that you better buy the best if you want MOA type performance.
However, if the chamber is cut right, there are lots of tuning and bedding tweaks that can make these rifles really shoot. Of course, proper handloading makes a huge difference.
The link is to a Canadian site which will contain lots of info on loading and on tuning. We play with the M305 which is a Norinco copy of the M1A. These rifles shoot extremely well when tuned. Certainly, they shoot as well or better then the tweaked Springfields.
So I hope that it gives you some ideas on how to approach this rifle. The single biggest issue is how well that chamber is cut. if cut sloppy, nothing you do will make that rifle shoot. Also, you should check the throat, if overly long, this will be a spray and pray barrel.
We have found that the standard Norinco chrome line barrel shoots as well as anything else, as long as the chamber is cut true. The same applies here.
Do a search for mysticplayer, and you will find my varied thoughts on this subject. You can also follow my website link for more info on tuning and loading for these semi autos.
