I own a Remington 7mm mag. Best and most accurate rifle in my collection.25 to .5 inch groups at 200 yards. With a better scope and someone with a steady hand would possibly get tighter than that. I would take a chance on it if the deal was good enough.
I have already passed on one of my guns that belonged o my Father to My son. He knows I plan to leave him mine. The only problem is He lives in New York and the gun laws there will not allow him to have some of the guns I own. He will either have to sell them or move to a state he can have them...
I purchased a training class on Vimeo. It has a lot of information provided from presses, dies, presses and accuracy. Over 80 videos in the course. Taught by Darrell Holland
I have used Nossler brass but, I way all my brass and seperate any that show a 2 to 3 grain weight differance. I group the cases by 10th of a grain differance before reloading. By doing this I find my groups run at 100 yards run at 3/4 to 1 inch.
