I suspected bore fouling to be the likely cause and paid more attention to the task. Using BoreTech Eliminator I can get many, many blue patches with no apparent end in sight. I only use a nickle plated jag and occasionally a nylon brush but continue to get blue patches. The bore also seems to have many tight/loose spots as the patch is pushed slowly down the bore.
As an experiment, I tried several patches of Wipe-Out "Accelerator" followed by an hour soak in Wipe-Out foam and didn't even get a trace of blue. Followed that up with Eliminator and get blue patch after blue patch and still a rough bore.
Any idea what may be going on here?
I've got a Broughton 5c on 300WSM and I cleaned after first 5 shots and that was it. I do have two cleaning rods one set up for brush other for patch and jags are from Benchrite.
I use Sweet's and I do let it soak and I tip my barrel down little.
If it was me I'd call Broughton they have a tracking system on each barrel they make by serial #.
Not sure if you ever read this
Since 2003 we have introduced 22RF, .224, .243, .264, 270, .284, .308 and .338 caliber "5C ®" (canted land) barrels. These barrels are showing exceptional clean ability, more velocity, longer barrel life, reduced bolt / breech pressure and extreme accuracy - shooting small groups at short and long ranges. We will expand this 5C ® land formation into other calibers and twist options in the future.
Each barrel is crafted with the highest of quality standards. If a barrel doesn't meet our quality standards, it does not go out the door. From start to finish we track what is being done and the results to each barrel by serial number. An individual tracking record is kept with your file for every barrel. If a customer has a question or concern about their specific barrel or would like a barrel similar as another customer, we can look it up and duplicate or continually improve the process. Our craftsman takes pride in every barrel we ship.
It is our commitment to you to craft the finest rifle barrel your money can buy. Give us a call at (920) 922-4882 to discuss your next barrel purchase. Quality, Accuracy & Customer Satisfaction is #1. We guarantee it!
