The general way of doing it is to adjust the hammer spring tension for somewhere in the ballpark of 97% of the maximum velocity. https://www.airgunnation.com/threads/regulator-pressure-vs-hammer-spring-tension.1133487

Quick update just to say I rechecked to see if the squeak disappeared after having reconfigured the check valve, and indeed it is gone.

Is the symptom that the plenum pressure is climbing to the same pressure as the bottle? If so, the O-ring on the regulator's adjustment screw needs replacing. The Snowpeak regulator probably looks different than this example, but the adjuster is the brass piece on the bottom right.

My standard Avenger makes a conspicuous squeak on each pump stroke when filling from a hand pump, so I suspect what you are hearing is normal. Side note, the check valve on mine started leaking a few weeks ago, and when I repaired it I swapped the check valve ball to a stem type and discarded...

Accurate and inexpensive is a tough combination. Most of the low priced pellets I've purchased over the years have been disappointing but there are occasional lottery wins that keep me playing the low odds game. Lately, the best value I've found are the Norma heavies in both calibers (9.1gr...

Shot count is on the low side but it is highly dependent on both temperature and manufacturing variables. Pretty much always going to have to do some tweaking of hammer spring tension to improve shot count, or better still, make an SSG for it. Regarding accuracy, please advise on the...

If the plan to install an aftermarket regulator falls through, measure the Belleville washers with calipers and see about installing thinner ones. Or if the current arrangement consists of nested pairs (( )), you can switch to singles ()() to halve the pressure range.

Good news, that will do nicely. Just make sure it is a true round head, not a pan head.

I do. The workmanship of most airgun barrels leaves something to be desired. Inexpensive ones particularly so, and frequently even the expensive ones. Barrel crowning - brass screw method Barrel troubleshooting and accurizing for the DIYer Bore lapping

Her sons are grown up and out of the house. The coyotes are her children now.

Yes, both aspects are specifically related to regulated airguns.

Relatively small cant angles can produce meaningful error at 100 yards due to the loopy trajectory of pellets. For example, a gun zeroed for 30 yards shooting at 100 yards with a scope canted by 2 degrees will be off by about 0.6 inch. By comparison, canting the gun by the same 2 degrees will...

This effect is usually indicative of having a little too much hammer spring tension. In other words, the gun is operating up on the velocity plateau and the velocity is highest when the reservoir pressure is highest, and gradually falls with the reservoir pressure. If you haven't already, try...

Please bear in mind that any scope mounting strategy which starts with a spirit level to level the gun is making a variety of assumptions about the perfectness of the gun, the scope, and the scope mounts. Granted, the result will almost always be better than eyeballing it, but not as certain as...

I only had a few different slugs on hand at the time, but mine would not group H&N in either .217 or .218, nor the FX Hybrids. Not even enough to be useful at short range (30y).
