[QUOTE="J E Custom, post: 364003, member: 2736"] Highdrum. There are many calibers that will wash out the barrels faster than others and the 7 RUM is one of them. So if you wan't to shoot F class matches I would not recomend it or some others because with practise and 60+ shot matches it won't last very long. If you want to hunt only with it you can get many years out of it. It is a very flat shooting round and currently the contender for title of the flattest shooting factory cartrige available. But there is a few things that can help extend the barrel life on any rifle and I can vouch for it because I have tried to make my barrels last as long as possible not so much from a cost standpoint but when you have an accurate rifle you wan't to make it last as long as you can. I like to pull a bore snake through the barrel every time I shoot it if possible this sweeps out all of the unburned powder and loose carbon that can/will ware the bore faster when you fire the next round on top of it, (If you want to see just how much is there from just one shot fire one round through a clean barrel and then push a dry patch through the bore and look at it you will be amazed at how much trash is there. When hunting I carry a bore snake with me for this (Easier that a cleaning rod) and after the shot it is easy and fast and the rifle is ready for the next shot. Throat erosion is another problem and can be improved some by different types and brands of powders, cooling time between shot (If Possible), Stainless barrels will normally hold up better (More ware resistant than chrome Molly) and Lead angle of the lands at the throat The reamer makers have a good take on this and will recomend the best angle for your use. The 264 win mag became notorious for this but most were hunting rifles and have lasted a long time with no more rounds than hunters put through them in a year of hunting (5 to 10). I lerned of the advantages of the cleaning/sweeping from a good friend that had fired an estamated 1500 to 1600 rounds through a 7mm STW and had not lost any of it accuracy. I have a 7mm RUM and plan of using it for hunting only so I am not concerned about barrel life. And I practice what I preach (clean after each shot if possible). All over bored cartriges are bad on barrels but as long as you are aware of this buy what you want and don't look back. But if you plan on shooting a lot of rounds weekly/monthly then there are better choices. Something allong the lines of a 280 rem. The best caliber for you is the one you want as long as you understand there is no free ride. Just some comments and opinions that may help. J E CUSTOM [/QUOTE]
