..............the 12 quad bike tyre one.............
While we were at the range yesterday we pulled the back of the suppressor off to do some maintenance.
Here is a pic of the inside.................
Note the baffles at the far end.........The wire holds the 'tetron' in place.
Here is a pic taken on zoom showing the 50m, 100m and 200m target stands.
We put another post just forward of the front of the suppressor and stuck a flat board on it so we could place the Chrony ............It seems to work although the trees around the bench seem to interfere with some readings, possibly due to the shade.
Loaded up some test loads for the 204 using 10X. Started at 24gr and went up to 25.
The first pic shows 4 loads from 24.2 to 24.5 ( one shot groups lol). Bottom hole is the 24.2 and top hole is the 24.6. Interesting to see the .climb as the velocity increased. Bloodhound was doing the shooting from his new Varmint laminated 204.
I loaded 5 of each powder weight so that we could firstly check for over pressure signs. The only load that showed any signs was the 25gr load. All the others were using match primers but the 25 gr load had CCI primers. The CCI primer was flattened..........the 24.9gr load ( using AR match primers) showed no signs of over pressure, which leads me to believe that the CCI ones are softer possibly.
After firing one of each load through BH's rifle, ( isn't that what friends are for- to pressure test new loads in THEIR rifles) I fired a few from my 204............then let the rifle cool down before shooting groups.
From a cold barrel, the best group I managed was this one.
The first shot was the 'cold bore shot' and is the one out to the right.
The next three formed the group. Its about .4 from my rough measurement using a tape measure. Load is 24.8gr under a 39gr Sierra Blitzking. Chrony showed it was travelling at 3684fps.
Load testing will continue................

Still enjoying the trip of a lifetime and making the best of what I have.....

Will be going back up next weekend to put a fan inside the suppressor (we need to disperse the smoke/heat as it causes a mirage effect). Will take the video and video both suppressed/unsuppressed shots for comparison....... ( did one after we set it up but cant find it in my pics folder)

Thanks.................we are planning to upgrade it to standard 4wd tyres. It will cut down on the mirage effect..............and allow more room for 'error', cos someone didn't take into account the height difference between the barrel and the scope.........................
