I will add my input as well. I have owned 3 DW all .30 cal. Accuracy was just about 3" at 100 yards with both 44 grain and hybrids. I thought the hybrids shot the best.
I know have a M3 with power block . Started with 700mm .30 barrel and only shot hybrids at 970 fps. Accuracy was def much better than all 3 DWs.
I currently and running the M3 with power block, tungsten hammer, and 800mm .357 cal tensioned barrel. Ammo is fx hybrids only at 980fps. I am using Donny's biggest moderator (emperor).
I can't even describe how good this set up is. I have my barrel tensioned pretty tight, about 3/4 turn after contact. It is by far the most consistent and accurate air rifle in any caliper I have seen. It is always 1.5 inches at 100 yards with 18 shots. I only get 18 shots from 250 bar fill to 165 reg pressure.
It is same hole every time at 40 yards. I never have poi changes. But again the rifle never leaves my house.
Now, I think this barrel tension system in .357 cal is the best because there is no room for o-rings with the liner. The liner is almost the same diameter as the steel barrel. There is a wrapping (like a candy cane)of Plummer's tape down the liner so it makes full contact with the steel barrel. Since the steel barrel is tensioned and stiff, I believe the entire system is stiff and without error.
Again just my opinion , but this is the best I have seen. I went out to 150yards and 5 shot groups are still the same. They just group in whatever way the wind is blowing, weather that be left or right.
I have a 1/2 spinner at 52 yards in my yard. I shoot it one time everyday whenever I go to let my dog out. I don't think I have missed it in 2 months. Wind or no Wind.
