I shot Lee Enfields and K31’s and Swiss M1911’s.
Sure the K31 might be a little faster than a Lee Enfield but not by much. The Lee Enfield is the faster turnbolt I have shot. Without a doubt a K31 is faster than a M98 type. I have to agree a M1895 Mannlicher is a stiff action and I would not categorize it as a speed demon.
Compared to a Garand, all these manual bolt rifles are tortoises in terms of lead down range.
The differences in rate of fire between turnbolt actions had to be inconsequential in terms of combat effectiveness.
I am of the opinion that while straight pull actions are interesting mechanisms, the lack of primary extraction is and was a problem, the complexity of the things is a real problem. Until you talk to Officers who have led draftees, you cannot comprehend just how stupid the bottom of the barrel draftee can be, and those are the ones who go into the Infantry! (There is a reason they are called "knuckle draggers"!). The difference in intelligence, the amount of training it takes to do minimal tasks, the speed of learning between draftees and our current all volunteer force which requires a minimum of a High School degree, I have been told it is amazing. Even the Officer core has its issues. I had to reassemble a couple of times a Mosin Nagant bolt for an ex Major. The Major could take it apart but he could not get it back together. He is not stupid in any way, but he sure is not mechanically minded.
Straight pull actions are by nature more complex than a turnbolt. That is very, very, bad.
Another fault, they are expensive to make. The Swiss are a rich nation and they make expensive weapons. Not every nation wants to put that much time and money into a service rifle.
If you want to look at a good design for a service rifle, look at the HK91. Simple to take down, simple to operate and very cheap to build. I believe the rifle was considered disposable as being able to make mass quantities is a better idea in a war, than spending the time and money recycling old rifles. After losing Armies of millions of men with all of their equipment in Russia, that lesson was well learned by the post war German designers of the HK91.
The Swiss continue to make some of the finest, most expensive service rifles on the planet. According to this, the last war the Swiss fought was in 1515,
