Beeman R7 Vortek PG4 Kit Chrono Results

So I finally got around to installing a Vortek PG4 kit in my .177 R7 that's been sitting on my desk for way too long.

Here's the results. String 1 are Crosman CPHP 7.9's and String 2 are JSB Diabolo Exact 7.33's

When I pulled what I presumed to be the original spring and seal, my shot strings had extreme spreads in the low 60's FPS and standard deviations 16-19 FPS.

The shot cycle is very much improved with a quick thud and that's about it, along with much improved accuracy and grouping. Not to mention this little rifle is now an 8-8.5 ft. lb gun after the spring kit.

PG4 Kit/Vortek vacu-seal in my HW30. Also shooting 8 to 8.5#. Great shot cycle and very accurate. Put an ARH kit in my R7. It's good and closer to 7.5#. Oddly, it can shoot as well, but tougher to do so.

Man, that's a killer looking stock. I think a larger, more adult friendly stock is the only thing I need now.
