Hammer Spring

Post by leverjc » Tue Mar 24, 2020 1:57 pm

I have installed Palo Verde Gunworks Hammer springs on two of my Marlins that work reliably in both but I couldn't find any info about using them with Henry BB. I have read about using reduced hammer springs that are designed for Marlins with varying results as far as reliability. I contacted Richard at PVG and he didn't have any data on it either.

I took a chance and bought one to try on my BB. The kit comes with a straight round spring with various inserts and washers to adjust the spring tension by altering the length of the spring. I loaded up 25 .357 cases with CCI magnum pistol primers and started adding inserts and until 8 out of 8 went bang. When I range tested with 60 rnds of loaded ammo with hand loads (CCI magnum pisol primers) and 2 different brands of factory ammo with 100% success. I ended up using 2 of the thicker inserts with one washer.

The nice thing about this system is that it is easy to tailor your hammer spring to a level that works for you. What I was looking for was reduced trigger pull and that is what I got. My trigger pull went from a little over 4lbs to 3.25lbs.

It sounds like you have found a winner but I would think about testing it with other brands of primers unless you always stay with the same one. If you ever shoot factory ammo, that could be a different outcome.

Travlin, I did try factory ammo both Federal and Hornady. I think you are right about more testing though. My use of the BB will be for Lever Action Silhouette so it will get lots of testing with my hand loads, if it was going to be used for hunting at this point I would add another washer for peace of mind.

Looks like about the top one third of the photo is showing. I applaud your efforts because I don't have a clue about any of this computer stuff. I could build the house to live in and and have a place for all the electronics but that's as far as it goes. Good luck.
