"Unless you have a Rekord Trigger or Diana TO6 trigger it isn't possible to shoot accurately time after time."
Complete nonsense! FWB, Diana, Anschutz to name a few all have match guns that have incredible triggers and have been used in Olympic and world class events to great effect.
The SW CO2 .22 pistol made in the 1970's could shoot high and low power with single shot loading. In "high power" it would go 450 fps at the muzzle and that pistol would be GREAT for 39 shots of .22 Pellets I always loaded back into the original SW .22 Pellet Can that had 200 rounds by Smith and Wesson instead of HN or JSB or whoever.
Those original pellets were followed by Crossman .22s while I shot the pistol modeled after the SW41 Match Pistol, the SW 78 G in .22 using 12.5gr cartridges.
The trigger on the 78G was "creepy" and you didn't know exactly when it would release except through the amount of creep to release the air. I realized it was a great handgun using CO2 with creep in the trigger.
If you have a rifle or handgun that has creep it means the time you start pulling slides along until you release the projectile. Then there are Two stage triggers. Two stage is Rekord and TO6.
In the air systems we have the triggers and the hook up to the rest of the rifle play into the scene; and having a "trigger that breaks like glass" is NOT necessary to achieve ACCURACY.
Therefore, I am saying PCPs all have triggers with a hammer slapping the reservoir of air to get consistency shot to shot to shot until it is time to refill.
The problem with triggering CO2 or Pneumatic or PCP is preservation of air! For consistency and long time performance. Pumping 10 times to get ONE shot from a pump up pneumatic is not my thing anymore; and the triggers attached to these are all substandard to making the most of the first shot.
I resort to air spring rifles for consistent accuracy and longevity and ease of shooting hundreds upon hundreds of rounds simply by cocking the barrel open and reloading,
I have the Daystate Huntsman Regal PCP .177 to stay up to date. It is a very nice .177 PCP and its accuracy is Daystate. It has to be kept around 200 BAR for maximum pellet shooting; but it is incredible at the BENCH REST!
But if I try to shoot the thing offhand it is TOO LIGHT and does not "balance" offhand as securely as an HW98 or D54 .20 both weighing much more than the super light Daystate Huntsman Regal of today. I don't shoot it because I like stepping out on my deck and cocking a break barrel air springer like the HW50 or HW98 instead WAY more.
The PCP is like a light weight thing with more velocity but not consistency after 250 shots at a sitting or offhand shooting.
All PCP and precompressed air mechanisms DROP velocity after a wavering "sweet" zone where 1 to 5 pellets may make the same exact trajectory.
In the springer you avoid the hype and concentrate on proper shooting and reloading techniques in the field. In the field you have to improvise with whatever you have--it is not going to be your sandbagged concrete bench rest holes in the field. You will wiggle and have to deal with it.
The stand up position is always the teller. Do NOT use a lightweight PCP in a stand up position in favor of an HW98.
Get the 98 and all is over in the way of air and problems with air in a consistent and long lasting rifle.
