Do you remember which which base you used?

Do you remember which which base you used?

These Griffin slugs are .217 HB-HP 18gr.

[buddyb]

Thanks 

[chico]

How do you know if you need .217 or .218 and what power setting do you use for slugs?

Hope it's okay to keep asking questions?

Buddy - thanks for asking these questions . . . i am following intently as i have a new, never fired Deluxe i have to disassemble and clean as there is a leak somewhere . . . would also like to drill ports while disassembled, but, like you, need to locate the correct ones . . .

[buddyb]

Chuck I'm new to PCP guns and have a boat load of things to learn lol.

I know where the transfer port is but not the exhaust port on the valve or the breach port.

I want to start shooting slugs for hunting so I'm trying to figure out what grain slug to use and the dimensions.

[chico]

Buddy - i'm with ya all the way . . . the Deluxe is my first PCP rifle, and i'm learning right along with you.

when we get this all figured out, maybe we can get together and shoot - we're not far from each other

[buddyb]

Sounds good Chuck

In about another six hours I'll be heading out with my 705-9 for a little plinking and hunting.   The other day I noticed I was getting low on BBT's for it so right now I've got everything warming up for another casting session

[buddyb]

Wayne, why do you prefer casting over swaging?

[Wayne52]

Big bucks to set up for swaging Buddy!

I cast up some more that I'll be using in my 705-9 this morning.

Looking to take the power to the max on my Sentry Deluxe.22. Looking for 8 shots & that’s really it. What is the max size I can take the exhaust port & barrel port to?? I don’t remember & when searching I get apt of oval type measurements for the barrel port & im not crafty enough for that type of work.

Well my bench gremlin struck again, 

I was cleaning/adjusting the 25 Cal Sentry trigger, to match my 22 cal triggers, after doing some of adjustments,
went to install the trigger, and I CAN'T find the front screw holding bracket part# 43, I have looked every where with no luck,
I know my bench gremlin got it, it must have enough parts to build another gun...........

Has anyone received parts from the Sentry factory?

I'll have to send them a email requesting a replacement part etc.

Thanks,
Don

A member sent me a PM basically asking about getting a probe, I told them to give Mike a call at FDAR and he had a probe for it in 5 days.  If Mike has the part he'll ship it right to you I'm sure, if not he'll tell you what you need I'm sure.  Mike is a really great person to deal with in my opinion. 

[buddyb]

I called Mike about a week or two ago and he said he had the probes and they're $30 ea. I was thinking of getting one for a spare.

[Wayne52]

I really like the steel probes for them, they interchange with my Liberty too.  I'd like to see the 702's with a side lever because they really are a nice gun in the field, don't get as many shots but very accurate for more of a carbine style like they are.  With that sale going on for $220 for them once they're sold out makes me wonder if Mike will get more of them cause these days people in general seem to prefer the side lever over the bolt action.

Some maintenance questions:

1. What oil do you use to lube your gun...for example:
    Trigger mechanism
    Pellet Probe
    The cocking lever sliding surface
    The stern of the magazine pin and the magazine release
    The magazine axis hole and the outer O-ring

2. It states in the manual to clean the barrel every 500 shots and to use a cleaning rod. Is an aluminum 22lr cleaning rod
    ok to use and do you use cleaning solvent or plain dry patches to clean the barrel?

[Racer1]

Ballistol,pull thru rather than a rod,and clean only when accuracy begins to drop off.
FP10 on metal to metal contact areas,but not anywhere it will come in contact with HPA.

I figured I'd give an update on the fill port o ring I installed about 2 weeks ago, the gun is now filling much better so I'll also be updating my other Sentry's as well.  For me it's only a 10 minute job replacing them and the only tools I need are the hex wrenches to take the fore stock off, fill probe  and a pair of rubber gloves to hold the air tube when unscrewing the fill probe/gauge assembly.  I loosen the fill probe/gauge assembly with the fill probe (very easy to do) and of course you need to degas the gun before you do any of it.



I also updated a photo that I used in some of the video's I've had in the hunting gate, the old photo showed 32 shots at 40-45fpe when in reality it's 21 shots@40-45fpe and 32 very usable shots.



I've recently been contemplating on buying the Sentry 705-9 in 25 cal and modifying also.  Mike M was saying how he's drilled the exhaust port very large on the valves but you need to drill them at an angle so it doesn't come through the sealing surface of the poppet.  On my prototype 25 cal the sealing surface wasn't bothered with the size I drilled it to but since then I think the valves have changed some.  These guns seem to be in a constant upgrade almost everytime a more recent lot is shipped.  The valves in all mine are just a little different however they could be used in any of them because the basic dimensions are the same externally.

[buddyb]

Thanks for the update Wayne. 

How do you degas the sentry? Also will those o-rings fit the fill probe itself that you plug into the compressor?

[Wayne52]

No they're way too small, there's no other o ring in the Sentry's as small as that one, it's the smallest of them all.  I did replace o rings on the probe that came with one of mine because they were wore out.  It still worked ok but leaked a little when filling a gun.
