One of "Your" air rifles..

[Mortblanc]

I was also thinking I must be doing something wrong or have the set-up wrong on the rifle. It is perfection in every other way, so I am going to work around the situation since I am used to solving these kinds of problems with cartridge rifles. Each one is an individual and I will find the proper combination for this one.

I specifically have a nice 3-9x BSA scope that has paralax adjustment down to 6M that I want to use for indoor shooting, which has been my disappointment.

I am going to look at the ball detent situation from the inside after disassembling the rifle. I am pretty sure they put the ball in from the back and secure it with a spring against a screw. If so I can probably get an extra turn to tighten things up.

"Back in the day" the 30 had a latch that secured the barrel in locked position. I wish they still did.

I have already ordered a one piece mount, and it can not hurt anything even if it does not cure the issue.

This little rifle is amazing to me. I am shooting it a ton and I am using cheap pellets. Except for the Coleman pellets the rifle shoots anything I put into it reasonably. I am getting one inch groups at 20m consistently using Beeman pellets that cost $4 US for 500 pellets, which is the cheapest I have found. If I can get the good scope on it I am sure it will do better.

The rifle will also do better when shooting the $12-$15/500 JSB pellets but I am having a ton of fun zipping out 500 or so shots per week, in reasonably close groups, at $4.

My PCP rifles have proven the same. JSB pellets shoot into microscopic groups at 35m while the Beeman and RWS pellets do around 3/4" and cost 1/3 the price of the JSB ammo.
