Spud, will do, I plan to start fire forming the 7.62 brass in the next couple of weeks. No shortage of porridge in this house either as I'm a Jock, I love the stuff.

In relation to chamber/barrel ringing you first need to understand the difference between fillers and wads.

Fillers do as they say and the fill the space in the case completely tween the powder and the projectile and if loaded properly with no airspace in the filler then the likelyhood of chamber/barrel ringing is greatly reduced. Spud in his vdeo is attempting to use fillers.

Wads are usually used in small amounts to keep the powder against the flash hole in the rear of the case for consistent ignition leaving an air space tween the wad and the projectile. This is what usually gives chamber/barrel ringing. This happens when the wad compacts, compresses or whatever into a solid enough mass for it to become a "projectile" within the case and when it meets the bullet the bullet becomes an "obstruction" thus leading to a high pressure area between the wad and the bullet until the inertia of the bullet is overcome. Thats what causes chamber/barrel ringing.

Personally I never use fillers or wads except in BP cartridges and ensure that if I am using a wad, say in a 577/4450 Martini it is part of the projectile column and if used as a filler it is well compressed.

In relation to fire forming cases I never use the semolina method described here as I still think there is a likely hood of airspace in the filler and the chance of separation is there, especially in bottlenecked cases as it is difflicult to effectively compress the filler. Airspace separtation within the filler can then create the "projectile obstruction scenario. I have seen various cereal filler compressd into solid slugs when used in cartridges.

That being said this method is used effectively by many but you still hear and see ringing happening too often for me to want to risk it.

When I have the need to fireform cases I use a cast lead bullet, simple, safe and using standard reloading and firing procedures.

Finally Spud I have to say that I was dissappointed to hear you say in the video that you didn't need to go down the range to shoot this load, from my stand point it is still a loaded round you have made and as such should never be chambered let alone fired unless it is aimed on target with a safe "approved" back stop. Please think about the message that you are sending out here.

No problem Spud we are all trying to do the same thing, share the little we know. :D

Trouble with me is I'm at the point where I've forgotten more than I know now. :shock:

Personally i enjoyed the videos. They were clear, consice and well taken. Personally i'd be interested in seeing the creation of a library of videos sourced from our requests. I want to see a good video showing how to make a casting from a barrel and action.

A quick question, what are the benefits of a AI rifle over the 'normal' one, e.g .243AI over a .243.

Almost forgot, what is the dinky little press and where'd you get it?
