Afternoon at the range.

[Rescue35]

So we have some lovely weather this weekend. It is currently 75 degrees outside  with a 5-7 mph breeze from the South. Its OK because my range runs South to North. I decided it was the perfest day to not do chores and instead, see if the new Shoebox compressor could keep up. It did.

I broke out the P'rod because the POI was off. I also wanted to swap scopes on the .22 M'rod. Tangent... Centerpoint changed there 4-16x40 scope. It no longer has the adjustable and locking "tactical" turrets. Instead it has caps. I will not be fooled again Crosman!

I figured as long as I was out I would try various pellets again as well as adjust both a little. The P'rod was still at factory settings and the M'rod had been turned up for hunting. I upped the power on the P'rod and lowered it on the M'rod.  This made both more consistent and gave me a better shot count with smaller spread on the M'rod.

My set up.


My range. 26 yards from here. I can max it out to 35 if shooting from inside the garage.


First up was the Pistol Marauder. It is set up as a carbine with the factory stock and a Centerpoint 3-9x32 scope that came with a Storm break barrel.

Pellet testing. Left to right are JSB Jumbo Heavy 18.13 gr (562 fps), H&N Crow Mag 18.21 gr (550 fps), and Predator Polymags 16 gr (572 fps).


Now that we know the JSBs are the best here is 5, 4 shot groups.


And the Chrony string that corisponds to the targets above, counter clockwise.

Now that I know it is dead on I refile it and put it away. I was slightly disaponted that the Predators didn't do any better, since this was the gun I bought them for.

On to the Marauder .22.

First I sighted in the new scope (green circle) then I shot 10 rounds of it's favorite pellets into one group (red circle).


As long as I have all of the pellets out and  plenty of air, might as well give them a try.

The Barucudas and Predators did OK. Its favorite is still the JSB Heavy 18 grains. I need to buy stock in that company.
Note the "rainbow" of the crow mags. From left to right that is how the shot.


Yes, a dime barly covered the JSB Heavy group.

I then took some chrony data to determine the balistic coeficent of the JSBs. After that I tethered to my tank and loaded some of the less desirable pellets for some plinking time. The barracudas knocked over my spinner and the monsters took a lot of pecans out of the trees.

I was only half way through this post when my Shoebox kicked off. I need to order a lot more pellets.

Talk about Dead on Nuts!

nice!  hey what spotting scope is that?

[Sqrl Klr]

Nice group with the jbs. The h&n's did good too.

[Rescue35]

Thanks,

The spotting scope is a cheap 20-60x barska. It gets the job done.

@Rescue35 thanks

Mr. Rescue35 how long does it take to refill your AR with the shoebox? I've seen video where it takes several minutes to refill.

I don't know. I've never filled a gun directly. I have several small SCBA "escape" bottles. One of which you can see in my first picture by the table legs. I've never really timed it but it takes about 4 hours to fill from 0 - 3500 psi and about 45 minutes to top it off from 2600 to 3500.

On a side note I have noticed that my guns gauges are off significantly compared to the tank gauge. The Marauder reads about 400 psi low. I trust the tank gauges accuracy however I do reference the guns gauge for shooting performance data as that gauge will always be with the gun.
