Not sure how accurate this chart is. I have nearly 1100 rounds through the Lilja 300 RUM using 100.0 of H50BMG and still holding consistent sub .5 MOA. The chart states <400 rounds for H50BMG. Also adding to the validity of this chart, 4320 is faster than 4064. The chart shows the opposite.

Alot more goes into barrel life than type of powder used such as powder structure (ball versus extruded), pressures encountered, bullet materials, cleaning methods and reletive burn rate. Relative meaning that 4350 could be used in a barrel that typically runs 4064 but due to barrel tolerences runs "hot". 4350 could burn more like 4064 in a given barrel with a given bullet.

I am pretty sure that if I ran RL19 in my 308's the barrel life would increase due to less heat and slower velocities. The problem is, I do not desire to run loads that slow.

Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.

Re: What's eating my barrel?

Just to be clear, this is a question and not a statement of fact as I have NO experience on which to base an opinion.

I'm told that the way to get barrel life out of the 6mm's is to use slow buring (single base) powder. H1000 has been mentioned specifically in the 6mm's. If this is so (and it's pretty much atated as THE answer), then the chart is questionable.

Not saying it's so, but all I've heard points to that. But then you know about hearsay! I just happen to trust the opinions of some of the parties who shared that information.
