Iāve seen that video. I have to say I diasagree with parts of it, mainly dealing with cold bore shots. I believe there are several other factors involved with ācold boreā shots including cold shooter.
How is the temperature differential between the first and second shot so different between the first and third, or fifth?
Iāve been blessed to fire just about everything small arm in the Armyās arsenal since well before 1982 when I joined. BARās, Browning Hi-:Powers, Thompsonsā¦
And Iāve also been very blessed to have fired an assload of our artillery systems. And mortars. And recoilless rifles. And the list goes on.
Why is it we would register one 155mm gun with several rounds, yet when the entire battery fired their first (cold) shots you had a perfect sheaf downrange?
Same with mortars. Thos tubes get hot fast. Yet when I trained on Soviet/Chicom mortars I saw the same thing. One mortar gets dialed in, then the other three (cold) fire with it - resulting in a perfect sheaf. In both cases you have to assume all were laid identically.
So back to the rifle. My AR shoots no worse on the first shot than on any subsequent shots. If it does itās me. Am I just one of the lucky ones whose rifle does not have a āconsistant and repeatableā cold bore error? You can read all about the subject and take either side you like, backed up with plenty of anecdotal evidence to support whichever side you take.
Iāll say this:
I rarely clean my rifle. When I do itās mainly the bolt and carrier.
I rarely clean the barrels in my pistols.
And again, my cold bore shots are just as good with my AR as any other.
And this is important: I hardly ever oil my barrel, and when I do, I swab as much as I can back out. Itās chrome lined. It aināt rustng any time soon.
Now when I throw a shot Iāll joke that it must have been my cold bore shot. But we all know humans have flaws, and Iām no less human than anyone else. When Iām off, āIā am off.
I learned quite by accident about oil fouling shots. Iāve been against using a lot of oil for most of my shooting life. Simply for one reason:
It attracts dirt, right?
Yeah. Tooling through the desert at 60 mph on a three day mission, my .50 may have needed a dusting off with a brush.
But no, the reason I always advocated using as little oil as possible is because when shooting a lot of rounds, on the one or two way range, that oil heats up and begins to burn your eyes.
As a result, I began to notice I had better ācold boreā shots than my teammates. Sometimes even whole groups at first. Then I realized they were of the ālight coat of oilā school of thought, including iside the bore. So I reserached it. Turns out oil, in any amount, is going to affect your shot. Makes perfect sense. It wasnāt that I was a better shot than my teammates (I was not) or that I had a better M4. It all came down to cleaning and oiling.
Sometimes during SFAUC, where we shots hundreds if not thousands of pistol and carbine rounds every day, Iād get those looks when I took my M4 into the shower. Yup, a little hot water, a wiping down. And then clean the bolt, the bolt cam and the carrier. Seven drop rule for oil. Mobil 1 synthetic by the way. Never had a even so much as a double feed.
So as for the video, I have mixed feelings. Are there 1 MOA guns out there? Most definitely. Are there 1 MOA shooters out there? Not so much. I am not, nor have a ever tried to be. For my purposes (I do not hunt. Not game animals at any rate) Iād rather have nice little spread hitting three different organs, than putting all three rounds in one.
Fire lapping can make your rifle more accurate. It also erodes the throat more quickly.
I find the best way for me to get my rounds as close as I want them is simply wait until my target is close enough. Unless Iām on the .50. If I can see him, heās close enough.
