Why has everyone gone with the flitz method rather than Tubb.

I have never used Tubb, I was scared to do it for fear of messing up my throat. I dont know if that concern is valid however.

Tubbs compound #1 and #2 are real course, for one thing, I had the .338 kit, decided I didn't want to use it, even though the reviews for it are excellent, I sent the kit back to Cabelas. I just flitzed the .338-06 barrel instead, when I took the barrel back to the smith to cut the neck a little deeper for the Weatherby brass, he was amazed at how good the bore looked with a borescope after the flitz treatment. It's all I'll ever use if it's good enough for him!! :wink: Tubbs cost the better part of $30, so for the difference in cost, the Flitz/JB or whatever you choose is much more economical and works!!

Tim.
Good decision.
A good cut rifled barrel does not need fire lapping with course grit. With the shallow grooves in the Handy, course grit lapping will just about ruin the barrel.

I always fire lap a new barrel but only with super fine grit 5 shots with 800 and 10 shots with 1200 grit. Which amounts to the same thing as flitzing.
But it is easier on my elbows. Even this system needs to be done with a great deal of care and with low velocity bullets in selected weights and ogives.

I did read a recommendation to forego the first 2 stages of Tubb

Fred, what grit level are the 5 Tubb stages?

Don't know the Tubb grit sizes, never used it. I have the NECO firelapping kit which has #200, #400, #800 and #1200 grits. I would not dare to use the two first ones on a good bore.

I have done two factory barrels giving it the full treatment, as directed by NECO. Both had were rechambered after. Both showed extensive wear on the throat after fire lapping, Both received new chambers and new throats,and both shot extreamly well after.

The fire lapping process requires that you slug the barrel after each step and in between to acertain that you are doing a proper job with lots of cleaning in between. I it a lot of work and checking and of course good results may not be.

Unless you can lengthen the chamber after I would not use the course grits.
