Dovetails like most things in the gun industry are goofy!
what a machinist calls a 60 degree cutter is easy in the gun industry.
In Machinist land it is an included angle, both sides of the cutter combined.
In Gunsmith land, of the outer limits. Brownells for instance measures the angle from horozontal to One side of the cutter. in this case 60 deg.
Now move to a rounded off 25 degree cutter per side.
Machinist dude calles this a 50 degree cutter.
brownells dude, a 65 degree, from horozonal to the cutting edge on one side is 65 deg.
makes sense right
50 degree included angle is less steep on each side and therefore a little stouter in my book
hope this helps,

Is the .330 X 60 degree dovetail called a mil. cut?
Agreed on that. So are the 1911 "shooters".Ok, Gun makers are a goofy independant bunch.
