Re: Futher 338 AM testing

New Shooter,

IF you take care of your barrel and be careful not to overheat it I would predict a useful long range big game hunting life in the 1000-1200 round range with the 338 AM.

It you run her to 70,000 PSI you will obviously get more throat erosion quicker but if you load to lower pressures and still let the barrel overheat with quick shooting you will do the same damage so no matter what you do you have to take care of the bore.

If I could get some bugs worked out with the forward ignition design I have been working on, I would suspect barrel life would be more like 1500-1800 rounds but I have to get it working properly before I can say.

In testing done before forward ignition has DRAMATICALLY increased bore life. That is down the road a bit though.

Re: Futher 338 AM testing

i was just talking about the barrel getting rougher due to the heat cracking and it's affects on bullets. not the twist.
