A second hand Sport was delivered to my door last Friday. After a quick inspection, I was very impressed. Blueing was nice, stock finish was perfect, shouldered great! And then I cocked it….. you can almost feel and here every coil of the spring as it rode over the rear spring guide. Shot cycle was loud and the “boing” but quick and snappy.
I opened her up to see what can be done. The rear spring guide is very undersized for the ID of the main spring. I managed a make shift plastic liner that helped quite a bit. After re assembly she was shooting FTT’s at 850fps and JSB 8.44’s at 865fps for 13.5 and 14fpe. Next the trigger. The length of the first stage seems to be the only thing adjustable by the screw. It is a very heavy first stage (1 pound ish) that rolls right into a 1 pound 5 oz second stage break weight. Still not having full feeling in my trigger finger after the sawzall incident over the summer caused me to struggle with the very narrow difference in weight. I dialed out pretty much all of the 1st stage and now basically have a 1 stage trigger that breaks at 1 pound 4 1/2 oz on average.
Had a full day of shooting her on Saturday. After a quick pellet cull, I found the FX 8.4’s to do the best. Accuracy during zeroing was promising. Consistent 1/2-3/4 groups at 30 yards and tried a few at 50 yards. (2) 5 shot groups were almost identical, put 4 pellets through a ragged hole and pulled 1 about 1/2” away. Throughout the day the shot cycle started getting springy and my “make shift” fix was to blame. Opened up the rifle Sunday morning and my sleeve was basically hanging off the rear spring guide.
I haven’t been able to find a kit so I got a little creative. I had a vortek PG3 full power kit for a Diana 34 collecting dust so with a little modification to the rear guide where it meets up to the trigger assembly I was able to make it fit. And OMG what an improvement. If this holds up it will be one of my finest shooting rifles. Managed an hour behind the trigger tonight before I lost daylight and here are the results.
Apologies for the long post, just wanted to share my findings.
