Hello AirgunNation Peoples,
Made a few changes to my new Wildcat Sniper MKIII in .25 caliber. Added plenum extensions, a larger transfer port, and re-tuned it for max power @ a 135 bar regulator setting.
Found that it has decent performance & accuracy with Air Arms & JSB pellets and also is getting on well with Nielsen Specialty Ammunition slugs. The barrel liner is the FX STX Superior liner and is 700mm in length.
The Wildcat MKIII is power adjustable via a hammer spring tension adjustment wheel equipped with seven (1 through 7) selectable repeatable power settings. It also has a externally adjustable regulator which is accessed by removing the stock.
Below are chronograph results of 5 individual pellets and slugs. Done after modifications and with the 135 bar tune. Velocities were shot from the MKIII over the chronograph on each HST wheel power setting (1 through 7) with each pellet or slug individually. So 1, 2, 3, 4, 5, 6, and 7 results represent a different HST power setting.
Any 1 through 7 HST power level can be selected and used at any time. From the chronograph information above the foot pound energies range from (lowest) 34fpe to (highest) 66fpe. These are the .25 caliber power settings that I find useful, but can all be raised or lowered with different regulator pressure set points and further HST fine tuning.
Accuracy has proven to be acceptable for the distances that I commonly take shots at game or on pests. 65 yards and closer are the usual distances when hunting that quarry present themselves in the thick wooded and brush-filled areas of Texas and Louisiana. It is reassuring that if presented with the opportunity the MKIII can confidently be used to take even further shots effectively.
Five-shot groups @ 50 and 100 yards with five different variations of lead, after the completion of all modifications. The Air Arms Diabolo Field 25.4 grain where shot on HST power level #3, and all other projectiles JSB King Heavy & Nielsen Specialty slugs were shot on HST power level #7.
Wind conditions.
Not bad... What do you guys think?
