The increase in power from 35-48% is really phenomenal.
However this is just for experiment only.

Basuda, If I Want to test it with Hurricane .22 and SDB 25 .22 with H&N rabbit magnum shots @ 25.77 grains, what precautions you suggest.
Regards.

Avoid hitting on hard metal surface.
Wear eye protector.
Do not put any liquid/Vaseline in the chamber.
Just use it at loading port only.
Aarmar has capacity to detonate but for SDB 25 it might not be that effective due to low power of main spring.
Excess use of oil/Vaseline will not induce dieseling.
Share your data.

Dear Basuda,
Very nice experiment with many detailed tips & information is useful. I wish to experiment with actual diesel and kerosene (which are real dieseling agents).

Anyone having any prior experience please inform. What is your view Basuda? Can it be experimented?

Dear All, as mentioned by Basu sir its dangerous to the rifle as well as shooter if you dont know what you are doing.
Few months back i brought SDB artemis and i noticed that lot of oil on rifle and i though its normal for new gun.But while shooting it smelled like burning rubber, after around 100 shots i noticed reduction in power and then i asked our local gunsmith about it and he said may be piston seal is broken, then i disassembled it and saw lot of oil inside piston chamber and seal is broken. Becarefull while dieseling airgun. I have attached the broken seal picture.

@Satverdar- The gun in use was SDB Sport , the most underrated AR of SDB Stable.
SimpChrony was developed by Ifgian Harshavardhan.He does not make it any more.
Attaching Photo.....

@Goru050- in your case it was a chamber Dieseling and that left adverse effect on the synthetic seal. :evil:
In my case it was breech dieseling and no adverse effect was noticed.
Members - It was done to do the experiment only and not for regular use.

Does dieseling damage barrel rifling?
