[QUOTE="Darryl Cassel, post: 2173, member: 34"] Hello Klallen The problems with the Remington brass are many. For 1000 yard match shooting, it is a flop in any caliber that I have heard talk about and used myself. You must weigh and mic 100 cases to get 10 that match in most cases, especially in the RUM cases. I have the 300 RUM IMP Tomahawk and wish I could get any brass other then Remington. The brass is very soft and simply does not hold up well in match shooting. The brass flows more and primer pockets expand more in Remington brass. Hence, the potential for real good accuracy is not there. As per the 7mm mag, 7/300 Weatherby -either of the two would be my choice over the 7 RUM, if only from the brass stand point. It is badly overbore and with a 4" shorter barrel expect 100 to 140 FPS less then the other poster stated. I think you stated you wanted a 30" barrel. That in itself would warrent using cases no bigger then the 7mm Mag, 7STW or 7/300 Weatherby. Any bigger case and the barrel would not be long enough to burn some of the slower powders completely. These are all suggestions but, keep in mind, if your after REAL GOOD accuracy, I don't think you will find it with Remington brass and the 7 RUM at full max power loads at 1000 yards. That's what the other poster is experiancing now. He may end up loading down (in volumn) to equal a smaller case size to get that accuracy. Out of 227 shooters in two classes at Williamsport, I believe there are 3 or 4 still using the 7mm bore and not doing real good with it as per consistancy. At speeds of 3150 to 3250 (168 gr MK) you may just find the accuracy level your looking for. When you say accurate, I think of shooting small groups at 1000 yards. The 7/300 Weatherby and the 7mm Mag (loaded up) may just be the velocity range for good accuracy. The 7/300 Weatherby held the record at Williamsport for a short time, 20 years ago. The 7mm Mag won some aggs back then also. "Top notch" accuracy is found with good brass plus lower velocities in just about any caliber. Norma and Lapua brass seems to be tops. Good luck to you.
