Shot count?

[Remchester]

What should the shot count be for my rifle? I've looked at data files and they say it should be 250 plus from a190bar fill Im getting around 150 from a 180 bar fill? No leaks ive checked...
Early 22 rapid7 block with short pre chamber
No regulator
400cc bottle
19' 22 barrel standard porting 3mm/3.5mm From
memory ?
Pip length is about 15mm again from memory?
Running sub 12 starts around 10.5
And upto around 11.7 in the curve and very consistent for an unreged

I also have a mk2 in 177 that has a similar low ish shot count of around 180 shots from a 190/200 bar fill..
Mk2 block mk4 trigger
400cc bottle
16' barrel standard porting 3/3.5mm from memory?
Standard Reg (as far as I know) set at 1350 psi
Pip length is 17mm from memory ?
Sub 12 running about 11.5 with15/18fps variation over a full fill
Again no leaks is there a magic setup ie pip length reg setting port size to get the most from both of the rifles any help and pointers will be greatly appreciated id phone kevg but don't like to bother him too much as he is always busy as!

just give me a ring m8.the reg is set to low it should be 1500 psi.low reg setting will lower shot count

Update for you kev after they been in the shed with you for the tweaks the mk1 did 255 from a 180 ish fill down to about 90 up from 190 shots(I did a recount and discovered my maths is shit!) So gained 60/70 shots! Used different pellet weights and head sizes as I figured I'd do some accuracy testing while I was at it.. took half a day! 🤣 the mk2 177 went up from 180 shots on a 190 ish fill to 220 shots with a mix of 7.9 and 8.44 pellets (think one mag or so was coming off reg tho) on a 180/190ish fill as my bottle was getting low so I would think with a full 200+ bar fill should be 220 plus on reg shots!  Thanks again mate you helped me out big time with these!

I have another question for you mate could be a daft one but.. can a 22 pellet go through a 20 cal barrel? Or do I have the world's tightest 13 inch .22 barrel?? I've rodded pellets through it and they are tight all the way down then they hit the choke! And take a proper shove to get out! Compared to other 22 barrels I have its extremely tight I have a 5.3mm pilot that won't go in the choke end at all but fits the breach end? But a 5.4 won't go in? Even 5.50 pellets are tight ish down the bore its just got me wondering?

I had a similarly tight barrel, was 5.39mm, you could see the difference in o/d where the choke had been hammered

Mine is coming in around 5.39 + - breech end and 5.29 + - choke end the thing is tighter than a Scottish nuns nunny!😅 made me wonder if it is a 'loose' .20 cal as it has no cal stamped on it think it may need the choke cutting back a little🤔🤔

[KevG]

if its realy tight all the way through the bore I would just get a blank.but if its accurate I would leave it be.a good polish may help slightly m8.
how did the filling bottle go on its test.dont forget I've got that part here that you left m8

Ill give it a polish and see how it goes the choke is ridiculous tight! its accurate enough but think there's a fair bit more in it..it will group ok with some and well with others then goes off the boil? It was one holeing 18 grain jsb but then will chuck one or 2 then back ok again? It seems to hate all but one of the mags I have they feel weird when the probe goes through them?? And are tight when closing the bolt?? Except 1 mag?? What part did I leave kev?  Can't remember what I bring over?
