Airgun Technologies Vulcan 3 (.25) vs Panthera (.25) reg pressure.

[explorer]

Hey,
Im considering between the V3 and Panthera/Dynamic. Im more about to get the vulcan but im afraid a little bit that the V3 needs much higher reg pressure (lower) shot count for the same projectile at same speed as the panthera because of much lower valve throughput. As i know in .22 the vulcan needs 200bar for the same energy as the panthera does at 165-170bar.
If you somebody own one of them, can you tell me what reg pressure you need for certain ammo/speed combo? For example 41 grain slug with 290 m/s ? Of course it can be different also.
Thank you.

Dynamic express 700 in .25
41grain Zan 315 ms 140 bar
55.5 grain NSA 289ms 160 bar

but I use and test different weights of hammers. as another barrel it is chocked and I don't know how the AGT v3 is doing

My VULCAN 3 700 mm .30 Cal shoots at 120 fpe with reg Al 140 bar.

My VULCAN 3 700 mm .30 Cal shoots at 120 fpe with reg Al 140 bar.

sorry, but the interviewer is interested in comparing the .25 caliber
if I were to compare calibers, the higher caliber will always have performance at lower pressures

The reg pressure on my V3 25 cal 700mm is 158 bar. It was tuned for 49.5gr Altaros at 916 fps/92 fpe. Derrick tuned it down to there because even though the original attempt was closer to 100 fpe it didn't shoot as well there.

I don't have any idea where the reg was set from the factory.

when I was talking with Altaros, he told me that the ideal speed for 6.35 smooth is 49.5 grain, but rather after consideration, they have 50 grain, they fly best at 286-288 ms
