rifling accuraccy

mark308

which is more accurate or longer lasting a cut rifling or button rifling? this will be a hunting rifle. I prefer my guns to shoot 1/2" at 100yds. my sakos do but they are the older ones. thanks

I'd expect cut rifling to be most accurate, hammer forging most durable and button rifling somewhere in between.

Krieger says cut rifling is more accurate; Hart says button. Of course that is what they sell. But they both sell to target shooters who want very good accuracy. I don't think there is much difference if the overall quality is equal.

So many other factors (barrel harmonics, crown, bedding) will influence accuracy, don't think well made rifling of either type will show a significant advantage over the other.

For any kind of practical hunting rifle, it's not going to make a difference. If you're shooting competition with groups in the 4's and 5's and want to get into the 1's and 2's, then research and question specific barrels by make and "model". For most of us the more pertinent questions deal with issues like action, trigger, stock/bedding, sighting equipment, etc.

there is NO most accurate method. The quality of steel, the attention during rifling, the time the gunsmith takes to square the blank in the lathe, etc etc etc all come into play. There is not one single winner on the benchrest circuit,...records have been set with all kinds of barrels. The shooter is the weak link as the equipment is far more accurate than a human.

Cut rifling tends to last a bit longer,..but can also take longer the "break-in" to where fouling drops off. Button barrels usually break-in quickly and often with only maybe 20rnds they will foul almost nill.

Hammer forging imparts the most stresses into the metal, button rifling less,..and cut rifling even less than that.
