Okay, the carbine went back today via FedEx. Now I have to wait for PA. The new scope & 3 extra mags are slated to arrived tomorrow. I've got some .25 slugs John Cripe (Johninthecamper) sent me that I've been wanting to try out, but that's now on the back burner. Thanks John!

Got my replacement Sumatra last Saturday. With work & the afternoon thunderstorms this last week, didn't get a chance to shoot it until today. Mounted the SWAT compact scope & after 8 shots, had it zeroed in using H&N Baracudas. Then tried the 43g EunJins & they worked great too. I had the power wheel set at 2/3 power with both pellets. As for the cocking lever, the new rifle doesn't have the issue with it kicking down. Accuracy is very good too. I'm pleased with this gun so far. Weather permitting, I'll chrony it tomorrow.

After church, got home & set up the chrony out back. Wanted to chrony both the 43g Eun Jins on full & 1/2 power & the 31g Baracudas also on full & 1/2 power. One of our Florida afternoon thunderstorms blew in out of no where, so I only got in the Eun Jins. Clearly this gun needs some tuning. It's got the typical Korean power curve, straight down. I'll play around with it for a while & then most likely be shipping it off to Will Piatt.
