How to Use a Corbin S Press - A Thread Geared Toward Beginners

[Airgun-hobbyist]

@Ta-Ta Toothie and @ndwind That’s really good to know. I’ve never asked and was unaware that they do this. With that said, perhaps this would be something more valuable for folks considering getting custom dies. For example, the Huben airguns have odd caliber sizing like .251, .252, or .253 (according to some posts I’ve read) instead of a regular .25 caliber. If one were interested in this sort of die set and another member was already using one, this would be an ideal situation to reach and ask another AGN member and owner of a Corbin die and press setup for some samples. This dynamic can make purchasing dies easier.

Buying a slightly oversized swaging die set and resizing down to the barrel's ideal diameter with a $25.00 Lee bullet sizing die kit is the way to go also. That way a .253 dies set, for example, can.be used for multiple manufacturer's gun barrels. Otherwise, a specific sized swage die for each barrel becomes rather costly.

@Esab To my knowledge there is a range of hollow-point depth that can be set by adjusting the floating punch holder. The hollow point depth can be controlled to varying degrees by how you set your punch in the floating punch holder. If you set it too far down
(or too deep), you can damage the punches and possibly the die. After a certain depth you no longer have a "hollow point." The further down it is set, the more resistance you will feel when engaging the ram handle. You should be able to use leverage without trying to use an excessive amount of force to turn the cam over. In this instance I would say that is an example of an excessive amount of force would be to attempt to use your body weight to pull the handle down in order to turn the cam of the press over at the bottom of the stroke. DO NOT SET THE PUNCH IN THE EXTERNAL FLOATING PUNCH HOLDER PAST THE LIMIT LINE. Be sure that the limit line is always visible. This is very important. Let's see what he has to add to this or explains differently.

@Esab Please keep in mind that if you've read this thread then you saw what I did using the two-step process. The steps I took were not all of the steps prescribed by the manufacturer. However, I didn't damage my equipment.

thank you buddy, at the moment I'm not super interested in Hybrids style slugs but have you noticed better Long range performance with this type or just better terminal performance?
In the mean time I will ask you a couple more things: Do you have an alternative product to Corbin swaging Lube? ( living in Europe is going to be very expensive to replace it if I'm running out) Do you wash the product out after swaging and lube the produced slugs with something different? What lead wire size do you use for .22 and .25 cal?

@Esab I'm not a long-range shooter. You can make lube, others have posted alternatives that they have used. I'm not too knowledgeable about the lubricants. for .25 a .247 sized wire is what's readily available to me. I don't wash anything. I leave the lube on my swaged slugs. I'm not sure if you're supposed to clean them off or not.

 

[Ta-Ta Toothie]

I don't wash them either and re-lube with the swage lube before going in the tin. My experience has been pretty good shooting lubed slugs. Rarely ever have to clean the barrel.

@Esab I’m thinking that the small number represents the lands diameter as the lands in a barrel stick up and will dig into the lead. Another member who has some good long-range slug postings is Scotchmo. Definitely look up some of his threads.

Having those numbers ( 0.2480 and 0.2534, checked twice they are correct) what size you would order? Any imput?
thanks

@Esab I would think to order according to the groove diameter. Then I would email Corbin Manufacturing to convey my measurements and be sure that ordering to that specification will produce the desired projectiles for the barrel producing that measurement.
