What kind of barrel life can I expect from a 7mm STW? I am using it strictly for hunting but want MOA performance out to 400 yards. How many rounds can I shoot before i see a difference in 400 yard groups? How would it compare to the life of a 7mm Rem Mag? I usually let my barrels cool between rounds. I dont fire them till they're smoking hot or abuse them in any other manner. They get regular cleaning with a bore guide every 50-100 rounds. I'd really like to hear from someone who owns one of these rifles. | ||

It wil depend a lot on bullets/vel. used. I read in one test article that w/ 140gr bullets you would see accuracy diff. in less than 1000rds. I have about 300rds thru my 7mm Dakota w/ mostly 160gr bullets. It's still shooting like new. LIFE IS NOT A SPECTATOR'S SPORT! | |||

I have two 7mmstws and have owned another.My first one was still shooting good at around 1000 rounds when I sold it to build another on a stainless action. | |||

Based on what I've seen of 264s and 7 mags, I would expect it to last about 3000 rounds, maybe more. It sounds like you take good care of your equipment, so 3000 rounds of full throttle ammunition shouldn't hurt a thing. Of the magnums and super mags I've seen go south, most were used for varminting, and more likely than not, were damaged during load development. | |||

I've posted this info before but for those that didn't read it let's look at it like this---- Barrel lenght is 26 inches. Takes a bullet about 1/2 milisecond to travel that lenght/ 500 rounds figures about 1 second-----soooo-- 3000 rounds works out to about 6 seconds of barrel life!!! The only easy day is yesterday! | |||

I'm hoping to use 154 gr bullets at around 3200 fps. | |||

elkhunter You should be able to get over 3300 fps with the 154 gr. bullet. | |||
