compared to cut rifling. And Cut will last 2 to 3 times longer.


Well... Not exactly.

For a similar rifling # and profile of land groove, I.E. height of lands (rifling profile), as well as same cartridge chambering. The button rifled barrel will last a tad longer than a cut barrel. The button barrel steel surface is work hardened during its rifling process, resists heat checking and errosion slightly better.

Typically say for a 22 or 6mm barrel. For a button barrel, one sees a 5-6 groove profile. For a cut barreled 22 or 6mm one sees a 4 groove profile.
In my experience 8 years shooting NBRSA/IBS 100/200 Benchrest (lotta barrels), these two types of rifling processes and profiles have for all intensive purpouses VERY similar competitive life spans. Same is true for the varmint hunter and paperpuncher, a similar barrel life span.

Now lets take an opposite approch.... Take a 6 groove cut barrel and a 3 or 4 groove button barrel. Now you will generally get 2x longer life span with the 3-4 groove button barrel. The 6 groove cut barrel will throat errode far quicker. And why it's rare to see a 6 or 8 groove cut rifled barrel.

Both rifling processes produce EXCELLENT barrels.

Hammer forged process really work hardens the bore but boy this rifling process induces A LOT of pent up stress in the steel that I do not believe can be entirely relieved. At least for a precision quality bore.

One must remember that barrels are despensible... They live and die.

I do like Tightgroups last statement:
"A lot more than just the barrel goes into winning a match."

So True....!
