Breaking in a tight new double rifle

[Wyatt Smith]

I hope I’m not derailing the thread too much, but does anyone know a good alternative to kroil? I didn’t know it was so hard to source. I guess I take for granted I can buy a large can of aerokroil (the areosol version) for $15.
I would assume any penetration oil would work, granted probably not as well.

Amazon. Buy a big can of it. You’re a farmer, so it might be worth buying a gallon for a lifetime supply trying to Un seize things on tractors.

The hazmat and shipping exceeds the cost of the kroil. Might as well go big.

Postscript: I’ll be darned! It looks like Kroil is now officially a seller on Amazon! They literally ran all those independent sellers price gouging off the site! 8 ounce can is only $22!

Kroil

Kroil is the trusted name in penetrating oil since 1939! Kano Laboratories offers a full line of penetrants, lubricants, solvents and additives, including Original (AeroKroil), Silicone (SiliKroil), and Graphite (Penephite) formulas.

I love the stuff! Nothing I have found works as well. If you soak an exhaust manifold bolt for a few days it will be wet all the way to the tip. We normally use the areokroil.

Lon,

If you do not have Kroil for the light lubricant Kevin described for surface smoothing- used Automatic transmission fluid will work in place of kroil.

@Wyatt Smith - The used ATF was shown to me by the old man who owned the local gun store in my home town.

Can’t tell you how many stuck shotgun choke tubes we removed by soaking the muzzle of the shotgun in a jar of used ATF overnight when I competed in college.

Yes Kroil is amazing & I agree the best, but burnt ATF fluid is both effective and cost effective.

Kevin..can you explain what you mean by pressure smoothening..? What happens to the metal surfaces exposed to pressure jolts over time..?

Hi Rookhawk,

Amazon? I do not think they deliver to Milibizi, Zimbabwe. Then we have customs and Zimra to deal with. I have about a 1/2 can left, it is at least 15yrs old. I will give the bearing surfaces a light coat and watch for galling.

I am not sure about some of the other makes of doubles, but the Heyms seem excessively tight. As I previously stated nothing breaks a double in like actually shooting them.

Hi Lon, without letting the cat out of the bag I know the situation very well. Relax though, this is good news, you don't have a problem there, you have a blessing. These doubles are made to extremely close tolerances. I am a metallurgical engineer as you know and i took a magnifying glass to these surfaces. Yes the action is stiff, but you will notice that it is uniformly so as it opens and closes. There are no high spots I could discern, just perfect still marry up all over.
It simply has to wear in a very little bit. My advice is:
1. Wipe off as much of the grease you put on the surfaces as possible.
2. Put on a very light coating of very light oil onto the mating surfaces.
3. Work the action until your arms ache, maybe three hundred times.
4. The action will have eased up, not from wear, but from pressure smoothening.
5. DO NOT use any abrasive creams or any type of abrasive, you are not needing to remove metal, just pressure smooth the mating surfaces.
6. When the action is as easy as you like it (it will always be a little stiff, it is the nature of the modern close tolerance), then clean off all the surfaces and rub on a minute amount of moly di-sulphide paste, very little and rub it in well. those surfaces will now probably not wear at ell for a very very long time.
7. Now just oil very lightly and you are good.

My double is now much easier to cock and on top of the above action working I have put about 100 rounds through it. Yours will loosen up, it takes a bit of time.

Kevin, Thank you for the advice. I will do my best to remove all grease and then try the Kroil if I remember correctly Safari Outdoors carries it, but I still have plenty. I need to make a version of a padded stiching pony up something that I can sit on insert the barrels into and then open and close the action, this leaves one hand free for drinking a cold castle.

Here is what I do to make a tight (especially double gun) smoother. Get or make some snap caps. You need at least 4 for a double gun. Turn on the news. Dry fire (and reload) at everything that makes your blood boil. Gives you some great practice and smooths out the firearm. It's also great therapy. Works for me on several levels.

Safe shooting

If you turn on CNN you will get it smooth in no time.

The Communist News Network (CNN) provides some of my favorite training images.

Safe shooting and safe training

Really great tips here on the very thing I am looking for. I shall use CNN for this procedure, as I really hate these cretins. Finally a good use of anger management. Thanks Kevin!

Just got my new Chapuis yesterday, man is it really tight, definitely won’t take it hunting until I break it in a bit. I’m fortunate enough to have plenty of reloading components at home to be able to spend plenty of time on the range with it and break it in a bit.

 

[Tokoloshe Safaris]

Kevin I had to think a couple of seconds before “CNN” dawned on me.
I have another Idea we have so many elephants around right now I could practice dry firing with snap caps. Or not!

 

[Aussie_Hunter]

I have always found the best method to fix this problem is use, whether it be a double or a bolt gun. I understand this doesn't really help you alot as it sounds like you don't have a whole lot of ammo just lying around but as some others have mentioned I would definitely avoid using abrasives to remove material.

As I mentioned in this comment, use is always the best method to break in a new rifle in my opinion and it has worked well with my new Chapuis double. I put 25 rounds through it on the first trip to the range, it was still a little stiff after this but much better. Next trip I put a further 20 rounds through the rifle, it's still quite firm/tight and takes more muscle to open and close than one would expect but 100% better than what it was out of the box. From here I definitely wouldn't say it needs anymore breaking in, I'm sure it will free up more in time but as it is now it's fine.

Forget snap caps Lon, use primers, then you can practise running too..

I bet you were a little stiff after that lot too!

haha yeah not as bad as you would think, I have put alot of rounds through alot of big calibre rifles over the last 3-4 years. I am fairly well used to it now.

With this continuation…is it necessary for the cross bolt to gull engage or will a smaller insert action be safe!?

ell check- ugh! Should be fully engage or will a smaller insertation be safe?
