.22 vs .25 hatsan blitz

I don't have the the big bottle on the Blitz yet. I do have the 700cc 4500psi carbon bottle with Altaros regulator on my Barrage though. With reg set at 150 bar I get 130 shots before it drops off the regulator. I have the bottle for the Blitz but haven't put it on yet because still undecided about installing a regulator. I never use full auto but may want too. What happens then if its regulated?
 
I am in patiently waiting for my Blitz in .22. The brown truck O happiness is due by 7 tomorrow. I'm certain a LOT of full auto is on the menu here, thus the .22 is the logical choice. Hard to beat a penny and a half a round from Wally for decent lead, so far my Beeman 2028 likes the Crosman CPHP great. I've been dreaming of full auto in a .22 for a very long time. I am primed rested and ready! Had not found this thread in my extensive research, the thread just reinforced my choice well. The .30 was very tempting, but not at higher than .22 PB cost per round.
 
Good luck with the bad trigger.

H&N Baracuda Power .22 pellets are doing the best in mine Hatsan Semi Auto.
I shoot a small frame double action .22 revolver double action, note I did NOT say I shoot it well double action. I've fluffed and buffed it, prior it was impossible. It's a geometry problem with that particular gun type. It does build trigger finger muscles. My son spends his days hammering a keyboard for a living, he can shoot it pretty well thanks to strong fingers. Thanks for the tip on pellets, I shall order some up, if I don't have some already, I ordered a bunch of H+N lately and the quality is great, I like the RWS hobby flat points in my 2028 very accurate. The Crosman CPHP's seem the best for slingin lead full auto.
 
Since the Blitz costs the same no matter which caliber you get it in then the only difference is in pellet costs. I added a DFL Ronin to my .30 and basically just hear the mechanics of the gun. Sometimes a moderator wont let the gun shoot full auto without a weaker spring installed, mine worked fine. If you do nothing but full auto shooting then you will eat up tins of pellets, lol. BTW, in full auto the pellets will clip unless you go up on your moderator size. I should have got a .357 Ronin instead of the .30 but I listened to the sales guy and was talked out of it. I guess if I'm doing full auto shooting then it's enhanced with the loudness of not being moderated.
Going way back to find this post but do you know where to get a weaker spring for the Blitz? How dojo know it’s weaker than the existing?
 
For general purpose compression style springs it's the diameter or gauge of the wire that determines "strength" there can be a lot to this and it's helpful if forum members share what has worked for them. I chose .22 for my Blitz and am also running a Donny FL Ronin in .30 caliber. No issues to report, just a significant reduction in sound. The Blitz is not very backyard friendly, not awful but loud enough to call attention to mag dumps, not a good thing. WIth the night vision video scope and the moderator, the next item to accessorize the Blitz would be wheels.:)
