[QUOTE="MagnumManiac, post: 2201631, member: 10755"] For a custom lapped barrel that doesn’t foul easily, it can handle 200-300 rounds without NEEDING to be cleaned. A rough factory barrel will foul quickly, therefore REQUIRING frequent cleaning. My match barrels shoot exactly the same clean or fouled, so cleaning them is not necessary. Barrels that change POI from clean to fouled, or cold bore differences, don’t hang around long for me. If lapping said barrel makes no difference, it gets sent down the road. I don’t want a barrel that takes several foulers to settle in, as people say. What point is having a barrel that you clean, then have to shoot bullets in it so that it stops spraying bullets everywhere? During a season of match shooting, I clean my bores with a carbon solvent and Hoppe’s Benchrest between weekends, this may be 88 rounds or 172 rounds. They get cleaned fully 3 times during this period so I can see the haze cracking and lengthening of the throat...I do not chase the lands either. I adjust powder charge to stay within a velocity window and tweak going forward. When the node is no longer achievable I set-back .100” or more and re-chamber as needed. I nominally get 3 set-backs per barrel and well into 3500 rounds as a rule. I shoot belted magnums, they eat barrels, but this can be managed by powder choice and bullet choice, temp stable powders help, but it is not always necessary to use them. Double base powders yield more Joules per grain of powder, burn cooler per specific weight and can lengthen throat life, as do ball powders. Pressure, heat and time are your enemies for barrel life, control this, to a point, and you will have good barrel life, abuse it, and you will not. Frequent cleanings with most of today’s powder formulations should not be necessary, they have ingredients to help them burn cleaner and deposit less fouling. Cheers. [/QUOTE]
