Question for someone that knows about firearms:
Is rifling applied from the front or the back of the weapon barrel (for example 4 slots,right rotation)

Morning peoples of the Holiday TK

DC, logically i would think from back to front based on the projectiles direction maybe?

Morning all.

It's a null question as to whether the rifling is applied from chamber or muzzle side of the barrel. The intention is to still have a consistent rate-of-twist from start to finish (unless it's a barrel with gain-twist rifling), and the rifle blank, prior to throating and crowning, is identical over the entire length. This applies to any barrel, irrespective of manufacture method (hammer-forged, button-rifled or cut rifling).

Also, unless you're creating an artillery piece barrel, which has to be able to compensate for the coriolis effect, the direction of twist has an utterly minimal impact on accuracy - so manufacturers just make sure the direction of twist is the same in all the pieces they produce.

*edit*

In case it isn't clear, to change the direction of rifling (left-hand vs right-hand twist), you'd use a different carbide rifling button, or carbide mandrel, or hook cutter. The direction of cut on these would be different for LH vs RH, but which direction you pull/push/hammer/cut in is still irrelevant.

I'm going to agree with Roomys on this. It makes sense that the rifling will proceed in the same direction as the projectile.
Or it doesn't matter at all.

I quickly skimmed this article and I didn't see any mention of direction but I may have missed it.

The only mention is button rifling, and that shows both pushed or pulled.

pressing all grooves at once with a tool called a "button" that is pushed or pulled down the barrel (button rifling);

It's actually simpler than you may think, depending on what software you're using on your PC for media server.
