Several months ago, I purchased a very nice 1960's RWS 48, and purchased - by mistake - a Vortek PG3-Steel <12 Ft LB kit to update the power plant. After I realized what I had done and it arrived, I decided to install it anyway. It certainly cocked smoothly and was a real pleasure to shoot, though I didn't find the accuracy to be up to my standards.
Sometime along the way, while discussing another matter with Tom at Vortek, I shared with him my order error and what I had done, and to my surprise, a few days later, a new spring showed up in the mail for me to swap out and make the <12 ft lb kit, a higher output kit.
I finally took the time to disassemble the rifle and the original kit this past week, and reassemble plus re-lube the rifle. When I was satisfied that everything internally was it should be, I set-it up on my indoor range and went to work to determine the best pellet match.
As you will be able to ascertain below, even though the power level and velocity increased dramatically, the accuracy improvement was unreal, shrinking many of the groups experienced at <12 ft lb by almost half.
Because I have several thousand AA 8.4 pellets, and the test results were within .02 of the RWS Superdome pellets that tested the best in this rifle, once complete, I zeroed the rifle for the AA 8.4 pellets and am now ready to move on.
There is absolutely no substitute for pellet testing to get the most out of your rifle. We have all been taught to believe that slower is better, particularly where springers are involved. Based upon this experience, this is not always the case.
