With short barrel you need big ports and fast valve opening to get those slugs up to speed before you run out of barrel. You could try light hammer and heavy spring, that should help a bit but it's the porting that holds you back. If you consider the bottle support it does not make the bottle any more rigid. What you can do is to mount longer picatinny rail to the drop block to protect the bottom of the bottle.

There's practically nothing where I'm at in terms of airgun support, so everything needs be ordered online. Good idea on the picatinny rail...I'm gonna have to look in to that.
If four weeks turns in to two months I would be asking about some info almost daily. What was that testing higher pressures as the bottle is ten years old? I don't follow the logic on that one? Marko
Bottles or vessels over 2" in da. are required to be certified every 5 years up to 15 if they are carbon fiber.
My experience with Brian was very good. He did a great job on my PP 750 a couple yrs ago. I have been shooting the 68 gr FX hybrids and having great results. I was really impressed with the results I got specially since it has a shorter barrel as well. Good luck, hope to see you posting on it soon.
I have bought some LDCs from them, they always gave a follow up call when shipped, and done in a timely manner. Heard other good reports on services rendered sometimes quality work is worth the wait.
I'm with you there, Marko. I'm trying not to bug him, but it is starting to get a little bit on the lengthy side. As for the bottle testing, he told me the bottle on the rifle was 10 years old, so he was testing it at higher pressures (230 and 250BAR respectively) to see if the bottle would hold up.

I really hope he is not "testing" with air pressure. Just hydro the bottle and be done with it. No other safe way to do it. If its carbon bottle and not damaged externaly, then visual check for corrosion in the aluminium bladder. No visual damage either side then it should be good to go. Marko

MarkoIf I remember correctly, yes a 200BAR rifle, although I believe the bottle is rated up to 250. And I honestly don't know how he's testing it. I should have asked.

I should have asked. 3000 psi so 200/210 bar on the gun and the bottle is indeed 250 bar. Sniper can be drilled out for barrel size porting in .357 so 200+ fpe is doable with stock barrel. With longer barrel 240+ fpe depending on barrel length.
