I like that Haenel Jager 9! Nice rifle and looks like you got a very good value for a Kipplauf.
Mine is a recently acquired Krieghoff Hubertus with steel receiver, so not the lightest version, but well matched for the caliber - .30R Blaser. It is "light enough", handles exceptionally well, and it shoots! I really like the Swarovski Z3 3-10x42 rail mount scope & Recknagel QD swing mounts too. I have a bunch of full power RWS factory loads ( like a .300 H&H) for hunting the big stuff, and have developed a nice mild .308 Win.equivalent hand load for everything else. Can't wait to get it out in the field!
