I have a Ruger Hawkeye All Weather 338Wm that is a heavy fouler and I'm thinking about fire lapping it.
Any one use the Tubb's system to do this?

This is for a hunting rifle with a factory barrel so I doubt if I can wear it out in my life time but if I can improve it I would like too.I'm not sure I see any purpose in using it unless you want to wear your barrel out faster. Kinda like cfe powder. Seems like a way to shorten useable barrel life.
But wasting time and money on ammo with no guarantees has me thinking of ordering a match barrel that will have a guarantee of accuracy instead.
Definitely agree with the gamble portion. For me it was simple economics: 50/50 shot it improved accuracy and cost of bullet system was $30-50.Thanks for sharing your experience Subwrx. I’ve always wondered if fire lapping would improve some of the extra rough factory barrels I’ve came across.
I never did take the gamble, and ended up rebarreling or just selling/trading for something else.
Pretty much exactly the same thought process as knuckleballz -
Definitely agree on the throat erosion/lands moving forward but I ended up not really caring because, well, sub half is still sub half! Doesn't really matter how you get there, unless you need to run VLDs for specific purpose (High BC) which may not like the added jump if you can't get close enough to lands.I've also used Tubb's Final Finish bullet kit (5 compounds 10 bullets each) on my .308 RPR after about 700 rounds. I was getting 5 round groupings around .60 - .75 MOA with hand loads and the barrel seemed to foul more than I thought it should. Since I had this many rounds down the barrel and on inspection with an endoscope, the surfaces looked pretty good for a factory barrel. So, instead of using all 5 compounds in the kit, I decided not to use the 2 coarsest compounds and follow the rest of the instruction best as possible. Like Subwrs300's experience with his .308, I also found than my throat had moved forward by about .010". When cleaning, there was a significant difference in that the patches went through much easier and the barrel wasn't getting as fouled as before. Using an endoscope again, the surfaces looked smoother and more shinny than before. Performance wise, I was then getting MOAs well below .50 (.35 - .45 and occasionally much better). So, I'm very satisfied that this made some good improvements as I had hoped. Though, I didn't particular like loosing .010" of throat that's already too long for my liking.
When using this product, just be sure to follow the instructions precisely.

Glad my experience is matched by others. Good post Straightshooter!
Thanks. Your post was excellent!
You're right about getting sub half. It's nice to know and have a factory barrel that can do that.
I just picked up and loaded some Tubb's TMS (Throat Maintenance System) to maintain a smooth throat. I think it's a good idea to be used as directed. And interestingly, Tubb even recommend this for maintaining high end/custom barrels (though I doubt competition shooters would be excited about using it ).
I'm still on the fence about a custom barrel needing throat maintenance but if it can smooth a slightly heat checked throat, it may have some merit. Does reduced copper fouling and roughness in the throat and first few inches really help precision for field use?
I don't have that answer but I'm sure benchrest shooters would say it's ultra important. Wish there was an *easy* way to test TMS on quality barrel without possibly ruining it in the process. I don't like the prospect of a $600 screwup that degrades an otherwise good barrel.
Amd on side note, I've learned that my ability to call and read wind is BY FAR the limiting factor at ranges past 800yds. I'm not so much worried about 1/4moa deviation from throat erosion over time as the 1-2 MOA misses from reading gusts incorrectly at that range.
I've read your post on FF at least 10 times over the last few years! It was/is a great right up on the product. Good to (virtually) meet the author!
Just curious: did you find the same forward progression of the throat/lands with the full FF system? I may forego the first two grits on any further use to see if I can smooth with less forward erosion of the leade/lands.Thanks. Glad it helped out some.
