    Just wondering how low (power factor) others have successfully gone with their G37 and still achieved solid, reliable functioning?

    I am working up loads that should range from 130-145pf using 200gr Rainer RN and Powerpistol.

    Thank, in advance, OD.

    My 200's have a PF in the estimated 150 range, using 4.0-gr of Titegroup or 3.6-gr of N310. One of these days I'll have to get out the Chrony and see if it still works.

    Actually, I have been meaning to ask you about the velocity of that load. Please let me know what you find with your Chrony.

    Also, do you find that at 150pf you are able to follow your sights easily through recoil? I have been struggling with this, but have also been using ammo at 180-190pf (900-950fps). I am hoping this will be better with lighter loads.

    Just learning. Thanks for your time. OD

    My G38 choked on 4.0 gr. of Titegroup and I was gargling brass at 4.1 gr.

    VV N310 & Ramshot True Blue are the two best powders for the GAP in my experiences with Titegoup close behind. I tried a little Power Pistol (borrowed form a buddy) and was not impressed with accuracy at all.

    Hit the range yesterday with my G37, 200gr Rainer RN bullets with Power Pistol. Tried velocities that averaged 650, 675 and 700fps. All were to slow. All ejected fine, but landed with 1-2 feet and most on top of my head.

    Would a 15lb. recoil spring (or less) be worth a try? I assume that the factory spring for the G37 is 17lbs or so.
    If yes, what would you recommend?
    Is this allowed in "Production" class or IDPA.?

    I have alot of Power Pistol, but would consider a change if that would make a significant difference.

    Or, should I just get used to shooting loads at 800-900fps?

    Just learning. Thanks for your help. OD
