Short and glorious. Most likley NOT what you wanted to hear.
I have had 2 300 RUM barrels. Both ate throats faster than hungry piranhas on a bloody rat.
I will say that my first one made it to 1000 rounds with acceptable accuracy. The problem wasent accuracy loss it was that the throat and bore cooked at such a rate that pressures would rise regularly from the increased friction. My loads would have to be readjusted periodically to accomodate this.
I thought it was all coincidental untill I tried another 300 RUM barrel of another brand and strted documenting more results. The second barrel had identical results only more extreme. Both were very easy to clean in the beggining and didnt take long for them to become a pain to clean. The 7mm will be even harder on a barrel.
