Airgun Technologies Vulcan 3 HP... .30 or .25 ?

[Jaxjax]

I'm looking to get one of the HP's . Just have to figure out which caliber. My shooting is 50-100yrds & alot at 100. My RAW has a .25 unchoked barrel & shoots 33 pellet just fine. so does my unchoked .30 for it. So my question is do the HP's still have the 3063 barrels ? & are the .25's unchokes also. My CZ gen 1 .22 is lights out with most any pellet but keep it as a 50 yard rig with pellets. Just need the positives vs neg to make the decision. If the mag limits it to just a few slugs in .30 that might make me go .25 .?

Ask @zx10wall. As someone who sells them and has set up a bunch (and is a great shooter), I would start by asking Derrick for his thoughts.

All Vulcans have unchoked barrels now. Yes, all barrel lengths and calibers.

The .30 mags will allow a 55gr slug. Going to 60gr or larger, for guns that I setup, I have 3D printed mag plates that are thinner allowing up to a 70gr slug.

Where can we order those mag plates? The same Vulcan mags work in the uragan correct?

The 30's are .3063 and the 25 cal are unchoked. Both kick butt.

I would rather use the Altaros Queen 60gr because the G1 BC is .245 vs .250 of the 66gr which means the 60gr is very close to the same wind drift but is 10% lighter albeit faster velocity.

Sure wish the HP version used a internal magazine depth capable of taking in those 60's or the 66gr!

Please share experience with Vulcan 3HP .30 Cal !!!!!!

It is important to know how it performs at 200 yards !!!

Avs 62.5 grain slugs fit in the 30 cal mags without any modifications. They shoot well in .3063 diameter w/ dish base.
