I have had an HW95 for several years that I use for pesting and target shooting, but being slow to reload, too many birds got away. I decided to take the plunge into the PCP world and got a used gen 1 Marauder along with a GX CS2 compressor. The previous owner seems to have tuned it well, initial testing seems to be pretty good for shot count. I was considering the Marauder and Akela, and decided to go with the Marauder because of the tuning capability would be a good learning experience for me. I know I already want to make a depinger, that gets annoying!
I have been testing different pellets to see what works best, I have an old box of Crosman Premiers 7.9gr that didn’t work well with the HW95, that shoot great at 25m, but at 35m the group opens up a lot. I have some CPUM from Walmart that do the same thing, great group at 25m, then much worse at 35. I have a JSB sample pack, the Exact 8.3 looked like a shotgun at all ranges, but the Exact 10.3 did really well out to 45m. The RWS Superdomes are my go to pellets in the HW95, but are horrible in the Marauder. Of course the expensive pellets work the best.
Does the issue with the Crosman pellets shooting great at 25m and then much worse by 35m sound like it could be improved by optimizing the velocity? The boxed Premiers in 7.9gr are shooting at about 950 fps. I plan on doing some more testing at different velocities, but it would be helpful knowing if there is a typical optimum velocity for these pellets, I couldn’t find that in my searching, so it looks like it depends on the gun.
