Like many kids my parents gave me a Crosman Marksman pistol. (A spring BB gun that looks like a 1911). When I was into IHMSA, I bought a Crosman MK II CO2 pistol in .177 so that I could practice in my basement.
A few decades ago, a co-worker turned me on to Beeman and the modern airgun revolution. I got an R7. About that time I started reading the Straight Shooters and the Yellow forums. I resurrected the MK II and the seals had all gone bad. I sent it to MAC guns for a refurb. Had it upgraded to a .22 (basically now it's a MK I) with a Walther barrel. Ported a little for more power.
I also wanted something with more power than the R7, but had entered my "must be accurate phase". I didn't want the hassle that comes with a PCP, so I opted for a underlever springer. After much research, I settled on the Weihrauch HW-77 in .22. Beeman imports it but only in .177 and .20 claiming it's underpowered for .22 or .25. I think they're wrong and finally got one from a Canadian retailer, Illingsworth -- now DAK Sport. They were wrong. At 20yds this beast will punch through squirrel and crows. I'm still waiting to find two lined up just right so I can pull a Quigly shot. Got a grackle yesterday on the bird feeder. Went clean through him and through the feeder leaving feathers embedded in the feeder on both sides. Oh and we're talking MOA with this sucker if I do my part. It sports a 5-15x40AO Bushnell Legend scope. I think I'm ready to upgrade to gas ram and may try the Remington. I may also look for a replacement ram for my HW-77.
I dabbled with a Crosman 2240 (.22 in CO2). Putting a longer barrel on it. Replacing the receiver. Adding a muzzle brake. It's okay but it's for sale with all the parts if anybody wants a toy to fiddle with.
That's my airgun odyssey. (and yes I still have the Marksman.)
