Thanks for sharing @datdotty! I see you use an action with a 90º throw. Have you ever tried a 75º throw? If you have, how do you feel they compare?
I have tried 75 degree bolt throw. They seem to be the new hot trend now.
Pros to 75 degree
You won’t jam your finger between the bolt lever and optics
If you have extended magnification lever on optics the bolt lever won’t make contact with each other like a 90 degree bolt throw would when you’re at max zoom.
Maybe ever so slightly faster in releasing next round into chamber.
Cons
Takes a little bit more upward force to throw the bolt lever upwards.
That’s really interesting insight. I’ve heard from so many places that bolt obstruction with optics is a common problem with 90º throw actions and I can see how that would be worse with an extended magnification lever.
The added upward force needed to open the bolt can make operation tricky unless you have practiced quite a bit and become familiar with the forces needed to open your bolt effectively.
Thanks for the feedback!
