Would any of you Delta Elite owners be wiling to take a pic of your barrel chamber with a case in the chamber so I can compare your case support with my new Fusion 10mm?  Thanks.

Here is mine:

Well it will not let me post my pic because the file is too large. Any tips on how to make my pic
smaller so it will post here ? My pic is only 1.6 Mb.

Here is a link to my pics on another forum: https://www.1911addicts.com/threads/ramped-vs-non-ramped-barrel-in-10mm-1911s.116631/

Scroll down to post #17 to see my pics. 

Can't expand the pictures unless you are a member of that forum :-(

This video shows the differences

Fusion seems to offer all three as an option - Standard, Wilson, and Clark. 

IIRC the Delta Elite is standard, as you would expect from a Colt, and is a tad notorious because it leaves a portion of the case unsupported.

So Neal, did you order your Fusion with a Wilson or a Clark ramp?

And for those of you "in the know" is either Wilson or Clark better?

phydaux,

   I did not order the Fusion, I bought it NIB on Gunbroker. Before buying, I asked the seller if
it was a ramped or non-ramped barrel. He replied "ramped". So I bought it believing it had a ramped
barrel. However when it arrived, I saw that it is NOT a ramped barrel and was very disappointed,
However, with case support this good, I think it is good to go. Also, my local gunsmith likes the
Clark/Para style better.

The delta elite has a bad and undeserved rap when it comes to case head support.

Colt proof tests every DE barrel.  Delta Elite proof loads by SAAMI spec are between 50,500 PSI and 54,000 PSI.  That is 35% and 44% above MAP of 37,500 PSI that factory ammo and handloads should conform to.  Unless you plan on loading wildly beyond SAAMI spec, a standard 1911 non-ramped barrel will serve you just fine.

Let me state I am not some purist zealot that thinks ramped barrels are an abomination and affront to the revered John Moses Browning, hallowed be his name.  JMB was a great guy and I love that his home was a short 40 minute drive from mine.  But in point of fact I don't currently own a 1911 with a frame ramp.  Every 1911 I have has a ramped barrel, because that is how they were made.

Why were they made that way?  Because that is what the market wants.  And as an added bonus they can usually make a bit more money, if not margin, on such a gun.  People pay extra for it, so even if your margin stays the same wouldn't you rather have 10% of $800 over 10% of $500?

Why does the market want it?  Well, that debate rages, but here is my personal take.  Back in the dawn of time (1980's) the IPSC pro's wanted to shoot major with 38 super without ruining their good looks when the gun blew up.  Handling over proof-load pressures required a ramped barrel.  And since those guys were shooting them everyone else had to have one, even though they didn't ever run hot ammo in their guns.  It's the old NASCAR adage of "wins on Sunday, sells on Monday".

Fusion is a reputable gun maker, and I have no doubt they have perfectly adequate case head support.  The pictures show that.  Stay on book, or not widely over, and you will be fine.

Thank you.
I have never had any issues with mine. I also don't exceed published load data but often meet the upper limits.

Thanks DenStinett for the pics. They lost a good bit of resolution in the transfer from the other forum, but I can still see the case support on the Fusion barrel looks pretty good. 

Thanks sqibullet for the information. I have two 38 Super 1911s with ramped barrels and thought I wanted my 10mm to be ramped also, but it looks like my concern was unwarranted.

I own Tanfoglio, Springfield (Nowlin), RIA (Para) ramped 10's as well as a Gold Cup Delta which is not ramped and never had an issue with the Delta feeding. Ramped barrels for me are generally a preference if available but if not it's definitely not a deal breaker.

I couldn't agree more.  I've had ramped and unramped.  Currently my only 10mm 1911 an an unramped Dan Wesson.  I've never had an issue with a load - even Underwood's great stuff.  But my next 10mm 1911 will probably have a ramp, because... just because the gun I want has one. 
FWIW - there must be something about living close to the home of JMB.  I'm only about 40 minutes south of his birth place.

Fo get about it.  I have an EAA Witness Match, a Dan Wesson Razor Back and a Colt Delta.  Measuring the once fired, there is virtually no difference.  Not so with the Glock,  Get one of those pass through dies and don't worry about it. 

You reloading?

Earl,

   I have been handloading for nearly 50 years and do not recall hearing of a "pass through" die.
Can you explain? 

Often marketed as "Bulge Buster" dies, these are effectively a Lee Carbide factory crimp die with the crimp components removed.  The brass is pushed all they way through the die and comes out the top, usually captured by a Lee container like they sell with their cast bullet sizer kits.

These are great for getting brass fired through generous chambers back into spec all the way down the case head.  They are often misused to recondition smiled brass that should be discarded.
