This afternoon I gave some attention to these two beauties.

The 97k .177 was a fun project:

I recently installed a V-Mach 12fpe tuning kit complete with Hybrid C-Form piston seal, V-Mach Rekord trigger unit with set back straight blade trigger breaking cleanly and very light. Internals cleaned up and polished, barrel polished with JB Bore Bright, Rowan MIDI muzzle brake and topped with a MarchX 8-80×56 on a custom Peter Matos picatinny riser rail with 20 MOA. Standard weight piston, no buttons on piston or comp tube, amazing what a good polish and a little Extreme Weapons Grease on the comp tube and ID of the receiver can do- rifle cocks ultra smooth. Early days, but shooting JSB Express at 800 fps very smooth and VERY straight.

The SLR 98 .177 carbine shoots 8.4 JSBs at around 800 fps and stacks pellets, gotta love that Anschutz barrel. David Slade went through this one some time ago and the rifle is so consistent it’s not even funny, and the trigger is one of the best I’ve felt on an SLR 98. Sightron SII Big Sky (SIII glass!) 6-24X42 makes this rig a pleasure to get behind.

Had no problems watching pellets fly through both😉

If the wind dies down in the next couple of days, I think a shoot-off will be in good order!

My hat's off to you! Fine collection of springers you have there-I remember your exploits from the old Yellow days. Are you still a foodie? At my house there's a "you kill it you cook it" philosophy which has gotten me to step up my skills on fish and game.

Hey John, thanks man, yes I do miss that old YF format, despite all the NOTWORK54 shortcomings. Some eat to live, others live to eat, I've always been the latter. Don't hunt much but when the occasional squirrel gets dispatched it will be cooked for sure.

This morning I shot these 5 shot groups with the 97k at 35 yards from a seated FT position off the knee using JSB 8.44, 4.53 head diameter, which fit snug and have proven to group a little tighter than 7.9 Express. Swirling winds, shots taken in quick succession during lulls. The group on the right has three pellets through the bottom left hole. I had to increased scope mag from 30 to 60 to confirm that the hole grew slightly wider.

So what can be further improved upon? Short of removing the scoped action and putting it in an FT stock, I think some minor mods to the foreend underbelly of the factory laminated stock to give it more stability on the knee and several ounces of weight added to the buttstock are about the only things I'd want to do.

Experience with the HW97k platform has shown me that in little to no wind, with good pellets, the rifle should be capable of shooting similar sized groups at 50 yards.

Too many projects going on at the moment, but it will be fun to document the progress on this 97k DIY "tune". Let's see how it goes😉

Don't ya hate it when some good quality pellets spill out of the tin? I had a bunch do exactly just that, into the bottom of a box that was full of TX200 spares (new pistons, old and new springs guides, etc). Not one to see these JSB 7.9 made in the Czech Republic pellets go to waste, they got the Dawn hydromassage treatment, followed by a blowdrying session and last but not least rolled on a paper plate that was previously lined with clingfilm and lightly sprayed with high quality Dupont Silicone lubrication.

Time to fine tune my short game, because at the last match I came up waayyyy too short, doh! 😉🤷🏻‍♂️.

I’ve since transferred the 97k .177 V-Mach kit fitted action into my old walnut JM stock. Happy that it was just a few clicks off on elevation to get back to my previous zero while in the laminated stock. I love the simplicity of a one piece, robust stock with a deep foreend belly; despite not offering as much adjustability as others it serves its purpose.

A couple pics from last night, it was starting to get dark, but seeing pellet impact was still fairly easy and it was fun to use the illuminated reticle at the lowest power setting. The journey continues, onwards and upwards!

if your house was on fire and you only had time to grab one, which would it be?

Oooh UM, it just got real up in here. OK, it took me about half a minute to decide: the rational side of the brain says take the 97k .177 scoped rig as is because there’s more a lot more money invested in it than the SLR 97.177 scoped rig. Damn, but the SLR 98.177 is a discontinued gun...ouch! Yeah, I would definitely grab the 97k rig then the hunt for an SLR 98 .177 in thumb hole stock would begin to replace what was engulfed in 🔥😉😉
