 That was my plan, just thought I'd let the guys here have a crack at it first since they are already familiar with it.

Thanks Matt for thinking of us first, sure hope you get it sold.

I tested the Griffin TC Hollow Base 20gr slugs shooting 5 shot groups and they were pretty accurate at 10 yards (one hole group) from my 705-9K.

.22   Griffin .217 TCHB   20gr   860avg fps   868 high/849 low   ES19/7SD   32.85fpe   4pwr level

I also tested the .218 Cup 24gr slugs, they weren't as accurate though.

.22   Griffin .218 Cup   24gr     820avg fps   822High/819Low   ES3/0SD   35.84fpe   4pwr level.

JSB Exact Heavy 18.13gr also shot one hole groups at the same distance.

I spoke to Mike at Flying Dragon today and he said he has plenty in stock and is expecting more soon.  I am and thinking I will order a 705 in 22 cal and Mike suggested a smaller valve with a little less power but more shots.

As I want to use this around livestock how is the noise level on these?

I am still wrestling with what air tank system but Mike says with his tune, and a 2000 psi fill I could easily use a good hand pump if I didn't shoot it completely down.  I am unable to get a 4500 psi fill in my area so carbon fiber tanks seem like they would not be a practical purchase.  He assures me I wont break a sweat with the pump so I may try that and look for a used steel tank - or are hand pumps just a bad idea.

Mike is right.  You probably wouldn't need to pump much beyond 2500 with the stock tune and still get 4 or 5 mags. Let Mike work a little of his magic and that 2000 psi fill may get you just as many shots - maybe more.  Even if you have a tank, it's never a bad thing to own a handpump.   I've heard the $55.00 Amazon pumps with the red end on the fill hose are good, but with ANY China pump you should disassemble and clean it before use.   Some reports of gunk in there from the factory.  Not pumping to 3000 psi will increase the life of that pump too.   The difference in those last 500 psi from 2500-3000 is remarkable.  It takes a lot more weight on the pump than from say 1200 to 2500.

Heck mine rarely gets down to 2Kpsi but I do have a stout hunting tune on it and rarely target shoot except for maybe five shots to make sure the scope is good.

[cclfn]

I am not planning on shooting slugs and really prefer a reduced power setting for close in work.  All probably less than 25 yards and sometimes inside barns and outbuildings.

Your slugs are very impressive and maybe when I grow up I will get a power version in a .25 for more serious hunting.

Hey guys, just ordered a 705 Sentry in .25 from Mike. For the life of me I cannot find a definitive statement on whether this model has a dovetail or picatinny rail for the scope mount - but it appears to be an 11mm dovetail in the photos I've seen and based on the 702's design. Which is it?

[cclfn]

Hey Josh good choice - I just ordered mine today as well but I got the .22 
I was under the impression that it had an 11 mm dovetail on the action and then there were picatinny mounts on the forearm top bottom and sides.  Here is Airgun Detectives review which Mike said is the same gun as the 705 Sentry he sells; it show the dovetail and rail configuration if you haven't seen it.   Opps I can't post the link yet but if you google it you can find it and actually he has a link on here as well.  He does a good job on his reviews.

[Wayne52]

My 702's and 705's have 11mm dovetail mounts for scopes.

[deadboots]

Thanks for the info, Wes and Wayne. Looks like I ordered the correct rings. Can't wait to shoot this thing! My pump won't be getting here until a few days after the gun, so I'll just be gazing longingly at it in the meantime...

[cclfn]

I have decided to forego the pump and will be purchasing a tank.  My knee does not handle the flexing required for a foot pump.  But I am still going back and forth on which tank style.  A carbon fiber or steel HP scuba either one will only get a 3500 psi locally but many other areas have  fills available for 4500 psi so I am thinking it might be better to cry once and be done with it.

My 705 .22 likes the JSB Diablo 18’s also.    Eight shots at 17 yd.

What power setting were you using with the JSB 18's.  I have some of those coming, and a tank, and a 705, and a million pieces of information floating around from days of reading.

So when you test pellets for accuracy is there a normal number you should shoot of each?  Should I shoot a few and if they are a pattern rather than a group, do I just move on to the next? 

Any suggestions would be appreciated.
Thanks

Here is where I ended up: Reg to 2100.  3400 psi fill, 881 fps with 2 1/4 turns in on the hammer spring – 32 shots ending at 2200 on the gauge.
I am making up a template for my 3-D Router so I can make a new wooden stock for mine along with a new style barrel / air tubes band for a better bipod mount.
Not really an “expert” to tell you how to figure grouping.  I just know that good mechanisms repeat as long as you find their sweet spot.

That's a pretty decent shot count, all on the regulator.
👍

Did you put a regulator in your Sentry or did you get your Avenger mixed up with this thread?

[OTmachine]

Oops! My bad.  Sorry.
Too many irons in the fire.
This is the Sentry picture.  18 gr. JSB, Power setting 3 1/2 @ 17 yd. (basement range)

Thanks for the information and update, I was thinking I missed a thread where you regulated one of these.

Look what came in the brown truck today!  Tank will be here first of the week but I will hopefully get to try out some different pellets this weekend.  Mike at Flying Dragon set this up with a low power tune for shooting around livestock and possibly inside barns/outbuildings.

[OTmachine]

Congratulations on the new Sentry.  They are a Good gun. I believe they can be regulated, but do not see the point in it.  I have talked to Mike M. before and appreciate his dedication.   Wayne52, a very helpful fellow, has done some mods to his and has some pretty impressive strings.  Haven’t done much to mine, as it shots pretty good stock.  I did order a carbon fiber tube off of Amazon to do some experimenting with a different shroud / LDC.  I will post my results when I get it together.

[buddyb]

Keith, I'm looking forward to the LDC project.
