Crosman, Benjamin Marauder .22 - With Mac1 Tune - Is In the House
I checked the tracking number and the UPS site said, "out for delivery", but when the package hadn't shown up by 6 PM, I figured it was going to be carried over to the next day. Right in the middle of dinner, at 7:30, the doorbell rings and it's UPS with my Mac1 .22 Marauder.
The first thing I did was to clean the barrel. It wasn't horrible but it did need a bit of a cleaning. I mounted an MTC Viper 4x16x50mm scope, in BKL 30mm high mounts on her, and filled her to 2500 psi for starters.
First thing this morning, I set up my pellet trap, and shot some groups with 18 grain and 15.8 grain JSB pellets. After getting her close to the aim point, I shot the four 5 shot groups shown below. I also tried the JSB Exact Express, and the JSB Straton pellets, but neither grouped very well in this gun. A different Marauder might shoot them just great. The next pellet I want to try in this rifle is the DYNAMIC PCP-2 tin pellet.
Tomorrow, I'm going to set up my chrono, and play around with setting her up to take 3000 psi fills and see what the shot string looks like. This is going to be an awesome hunting rifle. It is incredibly quiet. As a matter of fact, it's the quietest PCP that I own. $550 from Mac1 with his tune.
Tim at Mac1 Airguns, goes through the Marauders that he sells and re-cuts the barrel crown to make sure it is true, and perpendicular to the center line of the bore. He also polishes the leade into the rifling, removing any burrs that might shave lead from a pellet being chambered. He puts a high quality "O" ring in the breach, and sets the trigger to about one pound. He also checks to make sure that everything else about the gun is functioning as advertised. All of this is done for, what I feel, is a very small up-charge.
Anyway, here's the first four groups out of her at 20 yards indoors. These were shot standing, off of my Stoney Point bipod, with my right shoulder resting against the garage door. I'm sure she would do better off of bags on a proper bench. The green dots are .75 inch from edge to edge.
