Air Arms 400/410	4.46mm	Shoots accurately magazine fed.(10 shot group 6mm c/c at 25 yards). Increase in kinetic energy about 15% over AA field diablo pellet. Do not use 4.5mm body diameter, loss of energy and inaccurate.
BSA Scorpion	4.50mm	Shoots accurately (10 shot group 5mm c/c at 25 yards). Increase in kinetic energy by about 10 % - 15% over JSB 8.4 gr.
BSA Super 10	4.46mm	Accurate (9 shot group 6mm c/c at 25 yards), first shot falls through the magazine because of loose O ring. Increase in kinetic energy by about 15% over JSB 8.4gr diablo pellet
BSA Hornet	4.50mm	As per BSA Super 10
Daystate Mk3	4.46mm	10 shot 2mm c/c at 25 yards in single shot tray with high kinetic energy
	4.50mm	As above in single shot tray but less powerful than 4.46mm. Not recommended when mag fed, if mag does not line up correctly. Acceptable accuracy when mag. lines up correctly (7mm c/c at 25 yards). Increase in power between 15% and 20% over Daystate field 8.4 gr. pellets.
Falcon		Not recommended
FX and all badged FX models (unregulated)	4.50mm	8 shot groups 12mm c/c at 25 yards. Power increase by up to 15% if 4.46mm body dia. is used over 8.4 grain JSB.
Phoenix Mk2	4.50mm	BSA barrel (10 shots 4mm c/c at 25 yards)
	4.46mm	Walther barrel accuracy as above
Stealth	4.46mm	Very tight if there is no lead into the breech needs Piledriver pellet seater
	4.50mm	As above
Theoben Rapid (all models)		Not recommended because magazine/ probe does not correctly line up the pellet and some barrels have no lead into the breech.
Weihrauch HW100	4.46mm	Probe does not always line up pellet with centreline of bore which leads to fliers. Otherwise reasonably accurate. 14 shot group about 10mm c/c at 25 yards. Reduction in kinetic energy about 4% compared to JSB diablo 8.4gr pellets.
