Shot strings, sweet spot, fill pressure and the curves?
Tell me what is considered “normal” for a given power range? (I guess this is the correct way of looking at it).
I have my new Stubby HiFlo from R&L. It’s impressive all the way around. Powerful and ergonomic. I like it.
I guess what I”m looking for is some instruction on order of operation?
Should I look first for accuracy with a given pellet? Are there any rules of thumb on where to start from a fill pressure, velocity standpoint for a given pellet?
Once I find what it likes, then look for the best fill pressure that will provide the most consistent shots for the longest string?
What is a good starting point? I have a pellet sampler with some light and heavy choices and I have a tin or so of JSB 18.1. There’s been so much done to and with these rifles that I don’t want to try an reinvent the wheel.
Thank and all input is welcome.

Stubby with the hi-flo valve in it is my favorite airgun. Lots of fairly powerful accurate shots on a fill. Ergnomic with the Maddog stock and nice and compact. I started with the 22 barrel and found it finicky on pellets so I went to the .25 barrel ($117) and it shoots most pellets pretty well (this is a LW barrel thing). In the beginning I wouldn’t touch a setting on the gun from R&L – just try different pellets.
I found that the lghter JSBs and other 14.3 grain pellets and H&N FTTs did ok as did Cudas/Kodiaks but JSB Monsters, Predators, the 18 gr JSBs and others did not do as well with the 22 barrel. For the hi-Flo valve the sweet spot is closer to 2500 as a starter but you really need a chonograph to test it and adjust it.
I bought the gun as Stubby Extreme 22 initially and switched the tank/valves between my Condor and Stubby. I now leave the Extreme valve on the Condor exlusively using Surefire 62 grain slugs for larger critters.

libertyman777 , its all about what you want to do with it, tune for short minimum fps variation string, tune for a big shot count with bell curve, some like to tune to the max fps and shoot down from there.
When you get it, just shoot it, have some fun.with the standard settings you will want 18 to 21 grain pellets , any lower and they will want to run over 1000 fps, and you really dont want the 18 grain jsb over low 900’s for best accuracy. the 21 grain Kodiak does fine in the low 900’s , and up to 1000 fps,
everything you need is on this forum just do some searches and it is there for you.
you can turn the gun down in the 400 fps range with 14 grain pellets, or shoot 32 grain at 1100 fps,
May the fun begin. 🙂
