Does any one happen to know the twist rate on a 244 (not 243) Mannlicher Steyr rifle made in 1958?
You can measure it yourself by taking a cleaning rod that has a handle that swivels loosely so that it remains in the same position as you push the cleaning rod through the barrel which is turning with the rifling. Start with a cloth patch thats ( bolt out ) not to tight or loose in the barrel- attach a piece of scotch tape that hangs about an inch straight down to the rod near the handle of the reciever and push it into the chamber. Next make two marks on the rod with a marker - one at back of the reciever and another 12" back towards the handle. Push it slowly foward and the tape will spin so many times in the 1' mark that you made and it should give about a 9-10 count on the tape. It will probably take a few tries as you will have to trim the cloth as needed so the spin is about right. A cleaning brush may work also if its a smaller calibur. I got a 8 1/2 on my model S 264 mag in this way. Good Luck
