Here's the group at 20m. It was shot prone, resting the foreend on a sandbag. Possibly not the recommended test technique for a spring gun but I had to make sure I didn't hit the Chrony.

How Tight To Do Up Screws On A Spring Airgun ?
Springer airguns are notorious for crazy recoil that could make stuff come loose.
Breakbarrels also have some extra structural screws that a powder rifle doesn't.
How tight do people do them up ?
How often do you check them ? ( I asked one guy and he retightens every night he shoots.)
Does anyone use a torque wrench ?
What are they even called ? Do those cross screws have standard names ?
Which ones would you use loctite on and which colour ? Or do people just use a film of oil so you can feel the torque smoothly by hand ?

Recently, I found one had come a bit loose, but it goes across thin wood that could split, so I wondered ...
I think professionals tighten screws by hand but in the interests of standardisation I thought I'd try using the FAT wrench. Not sure if its a good idea or not. Most of the screws were already way tighter than the numbers below but this is what I've started with. My first trial settings are quite a bit less than people use on powder burner stocks.
1. Barrel pivot screw 20 in.lb
2. Cross bedding screw 15 in.lb This is the one that had come loose but I thought needed a gentle touch.
3. Front trigger guard screw 20 in.lb
4. Rear trigger guard screw 20 in.lb
5. Scope base screws 20 in.lb (Mount manufacturer Leapers UTG recommend more like 40 in.lb)
6. Scope ring screws 20 in.lb (Manufacturer: 25 in.lb)
I'd be interested to hear what other people are using and of course what they call them.
I haven't ever taken the stock off. Are there other screws inside that need regular checking ?
Setting up an airgun range at home
Hi Woody and Forum Members,
Have a look in the Arms Code and the requirements are that you don't "Annoy, Endanger or Frighten" anyone.
First you need a bullet trap (I used sandbags, with solid wood behind which I checked from time to time. Have a plan for disposal once the bag is shredded.) I used corflute to attach the target flat in front. Give some thought to your firing zone and safety of misplaced shots and ricochets.
Second you need to be discreet and have the understanding of people you live with. Spend half an hour or so planning and discussing things to anticipate any objections eg no shooting after bed time or while young kids are around; let people know when you're going to be shooting.
Third, there are guidelines for setting up shooting ranges (link to NZ Police range manual 2005) which will give you some good ideas. You could go whole "Risk Management" on this and write your own range standing orders and standard operating procedures if you like.

Ballistic Putty Pellet Traps
Hi has anyone used these ?
Looks like a wooden box with clay sort of stuff that catches the pellets.
Out of stock in the USA, presumably due to lockdowns.
Has anyone seen them for sale here ?

Here's a home made one on "Airgun Nation" forum. The plumbers putty looks a bit expensive $18 for 500g and hes used 12 lb (= $200 worth ??) and the Air Venturi has 10 lb of "Ballistic Putty" in it.
