[QUOTE="TracySes23, post: 1406929, member: 52763"] Kinda depends on how much time you allow between shots. After the first 5 shots, I generally wait between 2-3 minutes between shots depending on how hot the ambient temperature is. I never allow the barrel to become so hot it's uncomfortable to leave my hand on it. However I'm shooting the standard 22-250 in a LRPV Savage action. My barrel is a Shilen 26" Select Match with a .250 tight necked chamber. I've put 1100 rounds thru this barrel & the throat hasn't changed more than .010" to .015". I bought the tight-necked chamber for only one reason... To increase case life. To date I've reloaded my Lapua brass 14 times & the brass shows no signs of failing. I read an article at 6mmBR.com a few years back & learned that some bench rest shooters are getting 100 plus reloads from their brass, simply because the brass isn't worked as much. I use bump-neck bushing dies to neck size the O.D. in order to get the I.D of the neck the proper size. I neck turn the brass to a .012" wall thickness which gives me a clearance of .002" total clearance. I never use a standard sizing die anymore. My original standard chamber was .258". Neck sizing down & up again I suspect Im working the brass at least 80% less. that using the conventional method. From my perspective, there's only one downside this. You can't chamber factory ammunition in a tight-necked chamber or use un-turned brass. If I get a group over .375', it's only because of my inability to see well or a wobbly bench. I'm my own worst critic, I always take credit for flyers. I'm sure in capable hands It's not uncommon for me to get 3-4 shot groups from .1"-.3". My 77 year old eyes suck. I suspect if I live long enough, my barrel will last for another 3,000 rounds. Maybe longer if I get one of those barrel cooling devices. Just an after thought. The 53 grain V-Max has a higher B.C. than any of the lightweight 22 caliber bullets I've seen & better than some 60 grain & over. When I first loaded for it, I was concerned it might disintegrate from spinning too fast. I was wrong! It shoots as good or better than any other bullet I've shot. [/QUOTE]
