Hey guys some of you have been following my progress on the barrel issues ive had with the marauder field and target. A few of you helped me accurize the barrel and it is lights out with jsbs. Im super happy with the results. I got one ragged hole at 20 to 25 yards and thats awsome. However I was planning on using cheap ammo, cph. Well theres the rubb even tuned down the crosman premiers just fire a 3in group at 20 to 25 yards. Disappointment is the order of the day. I wanted a gun i could use jsbs in for competition between my club buddies and cheap walmart ammo for backyard fun. Its annoying to me that a gun made by crosman wont shoot thier own ammo, its why i bought it. The problem is not the power as some of u might suspect its the thin diameter of the barrel. Its resizing cph pellets at the choke and when pushed through by hand it hits hard resistance the last inch of the barrel. I would highly suggest waiting for the green mountain or lw barrels to come out for the field and target if they are not out already. However I can absolutely attest to its accuracy with jsbs. Just a friendly heads up. I know most of you airgun snobs only shoot jsbs but i love me a 6 dollar tin of 500. I gueas im just low rent.
