Scotchmo:
I shot my QB58 at last Sunday's CASA FT match. I had the weight up to 21 lbs. I shot well enough but I really did not like dealing with that much weight. Very light recoil but balance is not yet right.

I was also testing my new scope wheel (with extra data columns). And my built in caddy/handle. Both worked well. I usually case my guns between lanes but am looking for ways to speed things up. But I don't like seeing muzzles swung around with caddies, so I'll probably make a bright green muzzle cap (should always be unloaded, but I'll include a thick steel disc inside the end for extra safety).





I have been having fun making parts at my desk, using my 3D printer. Easier than driving the 10 miles to my shop to make metal parts. I will be back in the shop tomorrow, replacing some of the steel with aluminum and trying a rifle weight of about 18lb next.

Scott, I think that wheel is missing a column for "PHASE OF THE MOON" so that you can account for the effect of the moons gravity on the pellets  ;D

Scotchmo:
The QB58 shot OK at the last match with the RAM mount/riser attached but I did not actually use it as all targets were easily visible and no severe angles.

Today, I decided to actually try it in the backyard with different adjustment settings - not good!

The POI would shift significantly if the riser was lowered any significant amount. 1.5moa when lowered half way down. I had suspicions that there would be some difference but did not expect that much,

The mount works fine if you re-zero after each adjustment, but that defeats it's purpose for me. I'm going to have to rethink this. At this point I'm thinking of scrapping the Ram mount idea.

DRAGON64:
Nice work, what 3D printer are you using for the work?
