This is a strange report that I didn’t see coming. I’m going to let you peek behind the curtain today and show you things from my side. This report may be more helpful than some of the tests I write up.
Test the Bug Buster Accushot Pro
Remember all the things I told you Monday about mounting the new Bug Buster Accushot Pro on the RAW MicroHunter? All that you read was exactly as it happened, but there is more to the story — things I didn’t realize at the time. All of the shooting you are about to read about today was done with the JSB Exact Jumbo Heavy pellet.
I spent all yesterday working on mounting and zeroing the new Bug Buster scope. No matter what I did I couldn’t make it work. That’s why I ran Part 4 of the Webley Mark II. It was late in the day and I needed something to publish.
But I finally got the Bug Buster mounted and shooting where I aimed. I then shot several groups and the best I could get for 10 shots was 0.798-inches at 25 yards. At the end of the day I gave up trying to shoot decent groups and figured the Bug Buster was somehow faulty.
When the Lucid scope had been mounted previously, ten of the same Jumbo Heavy pellets went into a 0.741-inch group at the same 25 yards. I didn’t think that was right and I even said so in Part 4. “I sighted in with JSB Exact Jumbo Heavy pellet, so I shot the first group with them as well. Ten pellets made a 0.741-inch group at 25 yards. I think this pellet should be more accurate in the MicroHunter at this distance … .”
But, as large as that Lucid P8 group was, it was still better than the best group shot with this new Bug Buster scope! I know this is a preproduction prototype but I expected something much better than this. And I thought I knew what to do. I needed a scope whose history I knew.
Early this morning I mounted a UTG 4-16X44 Mini SWAT scope that’s no longer current but is very similar to this one. This is the scope I used on the JTS Airacuuda Max .25 caliber and I got a 0.29-inch ten-shot group with that one at 25 yards. So I know this scope can deliver the goods.
I sighted this scope in and shot one 10-shot group. That one measures 0.824-inches between centers for 10 shots at 25 yards. That ain’t right! This is a RAW that should put 10 pellets into around 0.25 to 0.3-inches or better at 25 yards.
Okay, it isn’t the scope. Now, what do we do when the muzzle of the rifle isn’t sticking out in the air but is buried inside a shroud or something? We look inside for streaks of lead, to see if anything is touching the pellet after it exits the barrel but not the rifle. So I looked inside, but nothing was visible. So I removed the muzzle cap and the air stripper.
The MicroHunter muzzle cap on the left and the air stripper on the right. Neither piece has a trace of lead. But with the air stripper and muzzle cap out of the rifle the muzzle of the barrel is unsupported at the muzzle end.
Hey airgunners, have you noticed anything? There is a pattern in the groups I have presented here. Actually there are two patterns. One is physical. The two groups I have shown you today are linear rather than round. But there is an even more dramatic pattern in the size of the groups. With the Lucid P8 — the first accuracy test — the group was the smallest. With the Bug Buster Accusport Pro the group was larger and with the UTG 4-16X44 Mini SWAT scope, which was the last test group, the group was largest of all. In other words, the size of the groups is increasing on every test. What could it be?
It could be a dirty bore. But I think it’s something else. When the end cap and air stripper were off I shot another group of 10 of the same pellets. This group measured 2.094-inches between centers. That suggests to me that the barrel is loose in the frame.
What to do?
I took the rifle to AirForce to let them look at it. When it’s fixed I feel I need to test the rifle again with the Lucid P8 and the new Bug Buster. I don’t have a problem with that because it gives me more time on the MicroHunter.
Today you got to look into my world where things don’t always go as planned. In a situation like this you can either curse the darkness or light one little candle. It’s situations like this that make us stronger and more knowledgeable airgunners.
