I came from shooting a Tikka T1X for over 5000 rounds. Getting used to the < 60 degree throw. I also own a Tikka T3X for a center fire rifle as well.
I was cycling the bolt incorrectly. No one ever taught me differently, so gripping it and lifting and pulling was easy and quick. 60 degree throws definitely make it easier. I hee'd and haw'ed waiting around for a 60 degree Vudoo, and eventually just gave in and bought a Vudoo recently.
First time on it, using my incorrect bolt cycling method I did hit my thumb once on the throw lever of my rifle - I mean there isn't any clearance really.
After following -
I've dry fired in drills around the house probably over 2000 times, and I haven't hit my finger at all on the scope and I haven't even worried about 90 degree vs 60 degree.
I started doing drills on how much movement my reticle moves when cycling the bolt. And I do notice that with my LoP and what's comfortable for me, I would prefer a slightly swept back handle. I'm about 1/2cm of reach from having a very smooth cycle movement w/o having to shift my elbow or arch my shoulder forward.
On my Tikka with a swept bolt, this means I can cycle my bolt shoot, cycle shoot, and my my reticle moves maybe .4-.5mils at most.
On the Vudoo, when I cycle it, to close the bolt, my reach needs to extend about 1/2 a cm, and I'll notice a 1.5-2mil shift to the left due to my shoulder arching forward for reach.
Though on the Tikka, with the 60 degree throw, there's more effort to lift the bolt, but with the thumb leverage it's okay, but I'd rather take a lighter/smoother 90 degree lift, than a heavier 60 degree lift I think. When shopping for my new center fire rifle, I've been looking at Impact 737R, Bighorn TL3, and Defiance Ruckus, and I believe they all have 90 degree throws and I haven't thought about trying to find something less and worrying.
So the only thing I want right now is something slightly swept back on the Vudoo... basically I'd like the RimX bolt.
@RAVAGE88 is there anyway to have something slightly swept for the Vudoo? I think the Benchrest model is slightly swept, but anyway to get it in my current one? (Just received mine 3 weeks ago).
