[QUOTE="brentc, post: 759607, member: 16938"] I obviously see things differently. I wouldn't even come close to saying most lrh rigs are overbore hot rods, many are but that's because people think that the "hotrod" is the only way to get out there. Let's take a look at your Edge, or even a Lapua. They are most definitely considered long range rifles capable of delivering massive amounts of energy at great distances but they are by no means a "hotrod" at 2850 fps with the heaviest bullets. You only need to drive the bullet fast enough to capitalize on the ballistic benefits of the bullet you intend to shoot. It's not about how fast we get to the target. As far as the RUM goes, especially the 7mm RUM, Grit said it perfectly. Tuneability has a lot of merit when it comes to committing a match grade barrel to something you waste half the barrel life on trying to find consistency. OP, please define your requirements. Why are you opposed to a belt and what are you trying to achieve? How much practical effectiveness do you actually think you will achieve by using 20 extra grains of powder to squeeze out an extra 50 fps over a 7mm/300? There are obviously differing opinions on what the maximum practicality is for a 7mm. If you are going for 1000 yards, which is about the maximum effective range for a 7mm of any type in a hunting situation, any of the 7mm Mags will work. If you need to extend further for hunting, you may as well make the jump to a big 338. [/QUOTE]
