Tuning Daystate Huntsman Revere Regulated

[Bobbybeef]

I have a 177 revere and i shoot FT with it. When you see the pellet down at 50 or 55 yards the pellet is cork screwing is there a way to adjust the regulator to turn it down to see if i can get the pellet to stop cork screwing ? Also at 50 yard benchrest some of the pellets tumble. I am shooting 10.3 Air Arms pellets I was thinking i could lower the reg so that i could slow the pellet down and get a better flight pattern ?

That's a good pellet. What is your velocity? Why do you think you should turn down the reg?

 

[Bobbybeef]

Its pushing 893, There is really not to much i can do with it but slow the pellet down thinking it would get better flight

 

[elh0102]

If I were starting from scratch, I agree, 893 might be a bit hotter than my target speed, but I really don't think that's your issue. That is still well within the range of velocity that I have found acceptable in most rifles. That's the good news, because as I'm sure you know, the Revere is not very owner-friendly when it comes to tuning. I recently bought a .22 Revere as a general purpose rifle, thinking, I'll either like it as-is, or sell it. Luckily, it shoots great, and I like it very much. The trigger would need a little work if were using it in competition, but for pesting and informal targets, it's fine. Because Daystate seems so averse to accommodating owner tuning, I would not choose one for competition. That said, they are otherwise great rifles, and I expect you can find your solution in pellet selection.

Would strongly encourage you to clean your barrel before doing anything else.

Strongly recommend watching Matt Dubber's Air Gun 101 video, Part 9, "How to Stabilize Pellets and Slugs." Discusses this problem and offers helpful insight.

Try the JSB 13.43.

 

[Bobbybeef]

I have scrubbed the barrel with baristol and patches.

 

[Bobbybeef]

Scott the gun likes the 13.43 but the barrel is to tight or the skirts to big a bunch of guys at the range could not believe how hard it was to push the 13.43 jsb into the chamber.and we tried from different tins

 

[ScottEnglish]

I use the JSB Exact Monsters 13.4, Cylindrical and not the JSB Redesigned Monsters. There is a big difference in fit and accuracy between these two pellets. My rifle went from average accuracy to laser beam with the switch.

My revere came setup for the 10.3gr Air Arms at 906fps. Which I use for FT also. Past 85yds I’ve seen some spiraling in the wind. I rarely shoot it past 60yds. I use 0db mod on it. Groups fantastic. Seems to group better with it on. 
Sounds like it’s clipping maybe?

You didn't mention if you are using a silencer on the rifle. If so, definitely shoot it without the silencer and compare. 

 

[Bobbybeef]

I shoot with a donny fl sumo but i took it off this past weekend no difference and its a 22 cal

 

[elh0102]

Bobby, at 50+ yards, you may simply be at the limit of that pellet/barrel/tuning combination. Since the Revere does not easily accommodate owner tuning, I would first try a heavier pellet with higher BC. And don't let hard chambering disqualify a pellet from consideration. 

 

[rptam1]

Maybe try a heavier pellet.

I would recommend the original monsters. Recent batches are not NEARLY as tight as the redesigned monsters. The .177cal redesigns that I've bought (4 - 5 different batches) have all fit too tight.

I don't know about the regulator but do know you can tweak the hammer. There were a couple videos linked in an earlier thread on how to do it. I did the process on my .22 and was able to go from 27 fpe to a solid 30 fpe. I ended up turning it back down to around 28 fpe as it seemed to lose accuracy and was far less efficient. I am sure you could do the same on yours and slow the pellets to your desired speed.Just do 1/4 turn at a time.
