[QUOTE="bigbuck, post: 412441, member: 18377"] I use federal 215 match primers in my .300 RUM and I shoot 210 bergers as well. I think the SD should be alot lower than that but I may be wrong I just shot my crony the other day so I can't say what my load is at this time but I have a nice group at 752 YARDS . My advice to you would be to start your load development @ 200 yards and once you have about an 1/2 inch group to 3/4 inch group ,move out to 300 and when it's nice in tight @ 300 go on out to 800-1000 yards Let the paper tell you what you need to know . my crony was the biggest lyer that i've ever seen . Not exactly what you was looking for but I atleast took a stab at it:) Just my opinion. Just noticed that this is your first post congrats and welcome to LRH someone thats a whole lot wiser than i will chime in hopefully...... BigBuck [/QUOTE]
