Russ:

I recently found out that some of my barrels were test honed at Benchmark as part of a sales pitch to another barrel maker. The results were perfect bore dimension from one end of the barrel to the other – substantially better than could be done by reaming alone. I suspect that affects accuracy.

Do you guys not understand that this does nothing for accuracy?

All this does is speed up the hand lapping process. It’s done between the drilling and the rifling….. after rifling would come the lapping…

What they really need is a way to test the steel for stresses. Thats what makes a good barrel. The machine work is important, but I have seen some major defects in barrels that were world class.

Kris – Bartlein is mentioned as using the Sunnen – right above the 4th photo.

This sounds exciting and hopefully proves beneficial with both accuracy and ease of cleaning. It’s gonna take a lot to get me to run anything besides hawk hill barrels the way my 6.5 creedmoor shoots.

So aside from Benchmark and PAC-NOR, are there any other manufacturers honing? Krieger, Bartlein, Rock Creek? Anyone know?

Benchmark and PAC-NOR also use the Sunnen HTE. At about $125K, not too many “boutique” barrel makers are using them. IMO, its worth asking your preferred non-Sunnen-HTE barrel shop to subcontract out this work. That’s what I have done. [Sunnen will find shops for those barrel makers that are interested.]
