MK3 - how many useable shots do you get? Also please post your gun's preferred fill pressure.

Fron 190bar fill i get 72 spot on shots

Depends on what you're using them for

I fill to about 195 bar (maybe a shade less) and that gives me plenty of shots for an HFT course - I think it was about 60-65 very consistent shots last time I bothered to shoot a string over a chronoscope.

If I fill to 210 it gives me about 110 usable full power hunting shots.

I run mine at about 775-780 fps at the muzzle with JSB's (4.52's with Napier pellet lube)

I fill to 200bar (card that came with it said 210). Only done one chrono check as a bit boring - 85 shots before noticeable drop in fps.

Mine runs approx 785-795 fps with jsb 4.53's

Lol that will teach me to type on the BBS whilst on the phone at work. Wasnt me guv - mine sailed through the chrono test at Lea Valley no problems

Thats the one

ho hum - I get around 40 with a 210 bar fill. And thats the optimum

Tony?

have you thought about sending it back to daystate?

(sorry mate, i had to)




i did actually watch Haakon chrono this yesterday and just the shots i saw droped over 50fps which aint good, hope you get it sorted as they are tops when working

[jinx]

At least 70 & i fill to 190 .cheers marcus

Same here, i reached this figure by shooting a charge over the chrony.

Silly question does your pressure gauge read correctly? Only saying this because I've had recent experience with a really expensive but faulty gauge.

All the best

Ps. You spoken to Joe Young yet?

not a silly question - but I'm reasonably confident in the guage - my 220 power curve result closely mirrors those achieved by Daystate last week (across the 22 shots they tested it for). Also I tested at 220,210,200 and 190 bar - it was 210 that seemed optimum - if it was one of the two extremes 220 or 190 I would question whether I needed to test other "indicated pressures".

results here: Fill Pressure vs Usable shots Daystate Mk3 sport (the Daystate test results are the dark blue line with diamonds)

And no I haven't spoken to Joe yet - but will do later in the week (hopefully).

thanks

just to illustrate what sort of effect this power drop has on trajectory I rustled this comparison up in Chairgun:
