Kodiak,
I purchased a Remington 750 .308 this past summer and had the opportunity to take it hunting this fall. Took a couple does with it. I bought this gun to use mostly as a bush gun. And really do like it. Yeah it has its issues but I thought I would find out for myself.
Jamming:
Yes, this weapon will jam but I would not say that it jams 'often'. I have never had it jam on the first cycle and I am inclined to believe that it is from a tight spring in the mag that creates a greater friction between the rounds. If the rounds are not seated to the rear of the mag then this is where I personally think the jamming occurs (during the pickup). This was also noticed with FMJ rounds where the tips would catch just before the chamber if they were not seated to the rear.
I am currently leaving one mag loaded in storage to see if this helps.
Accuracy:
This really comes down to the shooter and shooting mechanics. The cycling of the weapon does affect accuracy. From standing, I can never match the groupings I get with a 700 tactical, but I always hit paper at 200yds. And I do not believe I will ever see anything further than that where we hunt, so I am happy with it's performance.
I have also found that the rounds you use make a huge difference and I spend the money on the ballistic tips because the flat-tops were all over the place even from the bench.
Overall:
This rifle does what it can. If you are looking for accuracy then a Bolt is the way to go. But it is fun and you will never know if it is really for you unless you try it out. I wish I could find a pistol-grip stock for it.
