Yes, I was wondering how much the firer suffered too, but it may have been minimal as there would be no resistance to the escaping gasses with the side blown out of the case and the amount of blowby around the outside. It might have made an impressive flash, possible burns to the hand and face.... speculation, I know- any opinions?

I was looking through a folder on my computer and came across these three photos of a DP P14 that was fired with a 303 round. IIRC, this was done as an experiment by a shooter who remote fired the rifle. The bullet was recovered from where it had just entered the rifling.

It's certainly helped me with an ongoing discussion at work Amitikulu! Without photos such as this, it's extremely difficult to work out mathematically then amply illustrate to a not-as-technical-as-he-thinks-he-is idiot what will happen in relation to compressed gas, heat and shear strengths.
The distance the bullet travelled was interesting too at the CofR. This is where the friction starts to bite - literally- and once it does, like all things(?) mechanical, nature takes over, things revert to nature and take the line of least resistance
I'll be ramming the photos down someones throat first thing on Tuesday morning! Thanks Amat, fantastic..................!

I miss him too.

Nicely put...I have to agree (although his inter-service envy can be tough to deal with at times

That is hilarious. Reminds me of an Abbot and Costello skit. I went on and watched the one about the SFC becausse, well, I WAS an SFC for many years. Again, I can relate
. EDIT: I see this posted away from the link I was referring to on page 3. About the little animated figures on you tube doing the monotone exchange ref. reloading on the cheap. Sarge.

I do miss his more productive posts, but, I think it has worked out well for Ed and the moderation staff here, as compared to the alternatives employed by the ownership of many other sites.

I have had the opportunity to communicate with him privately and he has nothing but nice things to say OMIT THIS about the site and OMIT THIS SOME OF the folks here.
He actually does not live that far from me considering the expanse of the forum....I gotta free up some time to buy him a cup of coffee.
He has given me some help that has been invaluable.

The typical reamer hes anywhere from 6 to 8 cutting edges, so making a measurably out of round chamber is HUGELY unlikely! The same for "banana shaped" chambers- reamers don't bend- they either break or make an enlarged entry zone...
Crazy stuff!
How do these eggspurts know their chambers are "out of round"? They look at their fired cases and they see uneven expansion at the base. 
They haven't figured out that cartridges do not self-center in chambers that are slightly oversize - and oversize for a reason: to allow the rifle to operate with war-time quality ammo and dirty, often wet ammo at that.

You can't just make a statement like that and leave us hanging!!!!!!!
To say there is something wrong with a surplusrifle is one thing, but to imply it has a REAL headspace problem.....? 


Just adding another clanger to the quotes dept.
"Only experts should even attempt to resurrect a DP rifle depending on it's condition. We have numerous threads on the subject."

A clue...
OK, Son, I'll give you a clue:
The case was stretched about 1.3 mm compared with the reference.
