4ea. Thompson Center Arms Encore ProHunter G2 51 Pound HEAVY DUTY HAMMER SPRING Bellm Custom TC Encore & G2 Extra Strength Hammer Springs for faster lock time, better ignition, and better accuracy! A stronger hammer spring is usually an absolute must when a hammer extension is used, when headspace is near maximum or in excess of maximum, and/or when firing military type ammunition with harder to ignite primers. Heavier hammer springs are not a substitute for correct headspace, but do help stop misfires and improve accuracy, especially with the added weight of a hammer extension on the hammer. NO GUNSMITH INSTALLATION. ANYONE can do it…… just unscrew the hex nut the grip or buttstock attaches to and the old spring and strut drop out. Often times T/C locTights the hex nut, I think it’s better to completely disassemble the frame per our Trigger Job Instructions. 4ea. – 44 Pound Bellm HD Speedlock hammer spring, STOP MISFIRES and ideal with our hammer extension. In an Encore or G2 frame, the trigger/sear spring has to overcome tension from the hammer spring in order to rebound the hammer to half cock when you take your finger off the trigger. This is a CRITICAL built in safety feature in these mechanisms that prevents the hammer from resting on the firing pin with a live round in the chamber and the possibility of the hammer being struck and firing the round, such as might happen when the gun is dropped for example. When a lighter trigger/sear spring is installed, it often times can not rebound the hammer to half cock, and the hammer spring must be shortened to allow the trigger/sear spring to do so. Shortening the hammer spring reduces its available energy to drive the hammer forward. In most situations, a lighter hammer spring still fires primers reliably, BUT over the course of doing hundreds of Encore and G2 trigger jobs, we have run into a fair number of situations where folks get misfires after we have done a trigger job that also entailed shortening the hammer spring, ESPECIALLY WHEN THE COMBINATION OF FACTORY AMMO AND A SOMEWHAT DEEP CHAMBER RESULT IN EXCESS HEADSPACE OR WHEN SHOOTING MILITARY TYPE AMMO WITH HARDER TO IGNITE PRIMERS. In the case of excess headspace, what happens is this. Especially with rimless or belted magnum ammo and the barrel’s spring loaded extractor, as the barrel is closed the case is pushed into the chamber by the breech face and the case head remains close to the breech face when the barrel is closed. Before the firing pin can indent the primer, there has to be a stopping point in the chamber to support the case against the blow of the primer. This is often referred to as a “headspace point,” ie, that point that stops the cartridge from moving forward. It takes energy to move not only the mass of the cartridge forward, but also the mass of the extractor along with friction from the extractor spring. The energy lost to moving the case forward is not available to dent the primer and may result in an insufficient amount of energy remaining to reliably fire the primer. Thus the shooter gets a misfire. (You can experiment with this yourself. The first time I heard this myself, I thought it was silly, but it can be demonstrated in frames that misfire by first tipping the barrel up, bumping the gun to be sure the case back to the breechface, then slowly lowering it to fire on the horizontal and getting misfires. Then if you first tip the barrel down and bump the gun to move the case forward in the chamber, raise it to horizontal and fire it, misfires will often go away…. applies to both rimmed and rimless ammo, btw. If you are getting misfires in Encores or G2s or in Contenders where the misfires are NOT related to the hammer block safety try this experiment for yourself.) Misfires are not only annoying but can mean ruining an otherwise terrific hunt or losing points in a match. They can also result in disparaging remarks about the gun itself and the guy that did the trigger job on it! Not good! And of course, if you factor in harder to ignite military type primers, this can compound the problem of misfires. As the weaker hammer spring and misfires phenomenon became more apparent, we began installing slightly stronger hammer springs cut from blank spring stock as an experiment, and this stopped misfires. We are still experimenting with various spring tensions to see if there is an optimum tension, but in the meantime, we are now supplying three different tensions of springs. ALL SPRING TENSION VALUES LISTED BELOW ARE FOR SPRINGS THE SAME LENGTH AS WHAT WE USUALLY SHORTEN THE FACTORY SPRINGS TO FOR THE HAMMER TO ALWAYS REBOUND. OUR CUSTOM SPRINGS ARE GROUND TO THIS SHORTER LENGTH. ACTUAL POUNDAGE VALUES WILL VARY, ESPECIALLY IF THE SPRINGS ARE SHORTENED FURTHER. A STOCK factory spring shortened to assure the hammer rebounds is approximately a 30 pound spring. OUR CUSTOM “SPEEDLOCK” HAMMER SPRINGS: 1) 51 POUND is 70% stronger than factory and may prove over time to be the best for general use.
