[QUOTE="Fiftydriver, post: 152847, member: 10"] I would tend to agree with Catshooter on this one. AS you all know I have my personal line of wildcats that to be honest make the cartridges we are talking about look pretty tame and mild. Barrel life is in the loading and in the way the rifle is shot and cared for. For an example, many of my customer will take my 270 AM and load it to full pressures and get +3400 fps with a 170 gr class bullet. I personally load it to 3250 fps which is WAY off max loads and pressures. Why do I load it to this level and no higher. A .7 bc bullet at 3250 fps is plenty for my needs and barrel life increases dramatically compared to full pressure loads. Many look at cartidges with very large capacities and small bore diameters as a way to flat out horse power light bullets to hyper velocities thinking that will get them long range performance. This will work out to 500-600 yards but past that its still gravity that gets their goose. My theory is to take a VERY heavy bullet with a very high BC and load it to moderate velocities and let the bullet do most of the work. By doing so, pressures can be kept low, case life increases dramatically as does throat life compared to the same load ran to very top end velocity. The bullets do most of the work when they get in the air. One example of this is my 22-250 AI which I barreled with a 1-7 Lilja. I just used this rifle on an exotic game hunt to take a very nice Fallow Buck at 310 yards. This is not terribly long range but with a 22 cal round on a 275 lb animal its no small order. The reason I felt confident taking the shot which was a solid shoulder hold was the bullet I was using, the new 100 gr ULD RBBT from Wildcat Bullets. I only load them to 3030 fps and even at that very low velocity, it will still outperform all the lighter bullets at ranges much past 300 yards especially in energy. Best thing is this is a comfortable load, very comfortable in fact and I suspect that load will result in a throat life over 2000 rounds easily. In all reality, I will never burn that throat out long range varminting or predater hunting. If you heat the barrels up they retire faster. Take care of them, do not overheat them, clean them regularly and do not load to red line pressures and you will get more barrel life then you would ever expect. Push them to the limits and heat the barrels up, you will need a new barrel very quickly. This is true for any cartridge to be honest. Its heat that is hard on a barrel so if you heat any barrel up and keep shooting it you will get accelerated barrel wear. Some chamberings just get you to that point faster then others. Know your rifle and load and shoot it accordingly and you will be suprised how long modern barrels will last you. Kirby Allen(50) [/QUOTE]
