Merry Christmas, everyone. I am working on tomorrow’s blog today, so, yes, there will be one. Today’s report will be shorter, but it’s to the point.
Cleaning the rifle
Today I will talk about cleaning the barrel of the Sig ASP20 breakbarrel rifle. When Ed Schultz of Sig said that some of their new air rifles respond to having their barrels cleaned lightly, the jungle drums started to beat aloud — “But it has a silencer! The cleaning patch will get lost in the baffles!”
And, just that quick, I have finished this report. Because, like many other airgun silencers, the ASP20 silencer has no baffles. NO BAFFLES! So, there is nothing to grab your cleaning patch.
I showed you the inside of the ASP20 silencer when we toured Sig last July in the 4-part Sig Day report. Three “hair curlers” are lined up in tandem inside the can. They aren’t really hair curlers, but they look a lot like them, and several other airguns are also using them inside their silencers. They are essentially hollow tubes with holes on the sides where the turbulent air escapes. And they have no baffles. A wrap of felt then deadens the sound of that air.
Ed did say that where the spools connect there is a “step” that’s 2.3mm high. That’s 0.0906-inches tall. So, if you want some baffles, there you go. Ed uses a common jag to push patches through the bore. Jags are just pointed pieces of metal that have no good way of really holding the patch, other than they are sticking through it and pushing it in the same direction.
Why am I doing this?
You may wonder why I’m harping on cleaning the barrel today. I’m doing it because I mentioned it a couple reports ago and some readers started talking about the horrors of loosing patches in baffles. Well, now you know that there ain’t no baffles in the ASP20 silencer. So, I am about to clean the barrel. I use a loop instead of a jag, but you can use either one.
It took me about 10 minutes to clean the barrel, using cloth patches, only. I did wet some of the patches with Safari Charlie High Tech Gun Cleaning Lubricant, which I have found works well on spring gun barrels.
Starting at the top left and going right, and then down each row, left to right, here are 20 patches that went through my ASP20 barrel. The patches that are slightly yellow are the ones that have cleaner on them.
I used 20 patches in all. The early ones were hard to push through the bore, but after about a dozen patches they started going easier and the last few met with very little resistance. Patches used = 20. Patches lost in the silencer = 0. I even pulled a couple patches back through the barrel — just to challenge things.
In short, there are no baffles and there is no problem with losing a patch in the ASP20 silencer. If you do, just load a pellet and shoot it out. There is nothing inside the silencer to hold the patch.
More from Ed Schultz
Ed told me to try some Wrath Ballistic Alloy pellets. I told him I had some, but when I checked it turned out I had the lead ones only. I have the Crux pellets in ballistic alloy. I have asked him for a tin of the Wrath Ballistic Alloy pellets to test, as well.
He also said the barrel is tight and any pellet with a head larger than 5.52mm will fit very tight. So I have to consider that.
And finally he told me he is sending me a new screw for the rear triggerguard. That one is a wood screw that people are stripping out. I haven’t stripped mine because Sig warned me about it and I warned all of you about it in Part 4. This will apply to all rifles with serial numbers lower than 389. If you need one for your rifle, call Sig’s customer service at 603-610-3000, option 1, and they will send it to you. I imagine they will want to know your rifle’s serial number for their records.
Where does this leave us? Well, I think the next test is to shoot the rifle at 25 yards and compare the groups with those from Part 4. That will tell us whether the accuracy has changed from the cleaning. I may try a couple new pellets, as well. And, once I have the best pellet I think I can also test the difference on accuracy between a sandbag rest and an artillery hold.
