JSB exact. 22 15.89 gr vs JSB exact heavy. 177 10.34 gr

Chairgun gave me better bc with. 177 heavy then with. 22 regular exacts. 

I am thinking about buying. 177 vulcan or something similar.

What is your experience with. 177 heavy in wind. I know my 12 fpe with regular JSB exact 8.44 gr with wind even at 30y get pushed alot. 

I think heavier pellet with more power would do better. 

What bullpup around 20 fpe. 177 do you recomend? Accuracy is most important factor.

Thanks friends and I hope all of you are ok.

I have a .177 HW100BP-K. Mine gives best groups at 40 yards (the distance to my feeders) with Polymags. I've taken many hosp and starlings in winds to 10 mph. The gun shoots most pellets accurate enough to take starling sized quarry at 40 yards, including CPUMs and H&N Hunters. Today I received my order of H&N Baracuda Lights, Baracuda Match, FTTs, and Terminators.

Cea 1960 Thank you this one is interesting. Do you have k or long version. How many shoots on one fill do you get?

The BC is close enough between the two that I'd go with the 17 cal at a higher velocity. 

In my past experience with them, 10.3's at 915 fps and 16's at 730 fps, the 17 cal had less wind drift. Both are close in fpe at those velocities to stay under 20fpe to shoot FT in the USA.

Great thank you that is the answer I was hoping for.

I vote for the .177 also.

I just started using a Kalibrgun Cricket Compact .177cal and tuned it for the JSB Exact Diabolo Heavy 10.34g at avg. 885fps and It shoots pretty good in moderate wind out to 50yds where I’ve tested it so far.

Wow nice one AirRanger. How many shoots do you get and how accurate is it at 50?

If you are going to go with .177, you might consider the 13 gr. monsters. They will have a higher BC than the heavies. As long as your rifle has the power to push them out with enough speed for them to stay stable at the distance you're wanting to shoot at, these very well may be a better choice than the heavies.

You are right but do you know any rifles that shoot them accurate?

 

[AirRanger]

This gun is a laser, makes shooting tiny groups a breeze, this gun as it’s tuned will produce over 100 shots per fill. Currently testing other pellets at 115-120bar setting and find that this setting allows me to shoot my favorite pellet (10.34g Heavy JSB) at approx. 885fps but that reg setting also allows for me to shoot several other weight pellets at speeds that still maintain accuracy. Example: the reg currently set between 115-120bar will let me shoot the 10.34g JSB at 885fps but will also shoot the JSB Exact 8.44g & AA Field 8.44 at approx. 930fps while still maintaining accuracy, I can also shoot the JSB Monster 13.g at 810fps while yet again maintaining accuracy. I believe 120bar is the factory setting. This gun is really fun to tune!!!

You have a great little package there I once owned cricket standard. 22 but had problems with it. But everyone else seems to like them. Will see how I decide. This one is interesting but I like uragan compact too.

Alot of good pcps out there.

Thanks AirRanger for good info.
