LVSF 243 Posted January 4, 2012 Report Share Posted January 4, 2012 243 rifle barrel, the load I use is 70 grain blitz king and 42 grain varget powder. How many rounds do you think it would take before the barrel needs replacing? Link to comment Share on other sites More sharing options...

achosenman Posted January 4, 2012 Report Share Posted January 4, 2012 I thought the 243 was over-bore and was in fact worse than a Win 270 in that respect Just for the fun I used generic data from Quick Load with 42grns Varget and plugged the resulting numbers into “Barrel Life” It says accurate life will be around 1400rds. It will only give an estimate true enough and every rifle is different, but Varget burns hot and that doesn’t help. I guess the true test will be when it returns an unacceptable level of accuracy for your needs. Either way I’d just shoot until it won’t, then stuff another barrel on and start again.

223magic Posted January 4, 2012 Report Share Posted January 4, 2012 243 rifle barrel, the load I use is 70 grain blitz king and 42 grain varget powder. How many rounds do you think it would take before the barrel needs replacing? Same question please for a .223 using 55 grain balistic tip, how many rounds before I should consider changing the barrel. Any ideas please.

achosenman Posted January 4, 2012 Report Share Posted January 4, 2012 What type of powder and how much? I'll run the numbers. My 223 has an expected life well in excess of 5000rds Link to comment Share on other sites More sharing options...

Again using semi generic data and predicted pressure, you are looking in the region of 7000rds plus. Obviously it depends how you shoot it, hot/long strings etc. ATB Link to comment Share on other sites More sharing options...
