I noticed in the pictures that the bearing surface looked longer. Given that its well known that longer bearing surfaces lead to pressure limits earlier, I wonder why they made them that way.

I'm guessing they had to have the long bearing surface to get the BC they were after. I'm not complaining. I'm getting more velocity with less powder and no pressure signs plus they appear to be an accurate bullet. I'm sitting here right now contemplating a powder switch for the 300 RUM. Since the bullet is rated for only 3,000 fps impact velocity (Hornady says the bullet will "stay together" when it impacts an animal at that velocity or less) I'm thinking some H1000 may be a better choice than the RL-33 I have been using. More temp stable, probably better ES and a little less velocity which in the case where I stumble into a herd of elk at 40 yards (which I have done more than once) would be a good thing.

Couldn't make up my mind so I loaded up a few rounds each with the 212 ELD-X and US869, H50BMG, Retumbo and H1000. One of those ought to get me where I want to be which is on an accuracy node and in the 2,900 to 3,000 fps area. As I recall there is a node in the mid 2,900s. Once I get those powders calibrated I should be able to dial in the velocity I want. I'm hoping H1000 is the winner as I like it for temp stability and ES.
By the way, while looking up 300 RUM load data, I noticed that the latest Hornady handbook has the load for Retumbo and their 220 grain round nose crazy hot compared to Hodgdon data, Nosler and others. The difference is 7.0 grains!

This might and probably is an error. A call to Hornady is in order.
Probably more accurate data than the soft load data the others provide. I have always ran waaay more powder than hodgon load data with very little psi signs.

Hornady lists 96.1 grains as max for 220 grain round nose. Nosler says 88.0 grains is max for their 220 grain Partition.

Why is that suspicious? I thought that was the point...no pun intended.
As far as I know, the 6.5 140, 7mm 162 and the .308 208 AMAX have all been 'discontinued' and replaced with the ELDM, which only has a heat shield tip a top the original bullet. I believe they are identical except for the tip material.

I had heard a couple months ago from a pretty reliable source that the
eld-m's are just a re-tipped a-max so if my rifle don't like the 143's I'm gonna try them my wife shot here deer @ 550 yds with a 6.5 Creedmoor shooting the 140 a-max Hornady factory ammo and I was fairly impressed with how they performed

Well, the 200 eld-x is a typical hornady...
I just popped off a .7 moa 5 shot group at 200 yesterday with my new 300rum using the 200 eld-x and 99gr rl33 in rp brass with a 215. Zero load development, simply seat the pill to fit the mag and let her buck with a healthy charge of powder.
Now .7 moa doesn't sound great until you realize I had a full inch of crosshair dance in the mirage from barrel heat in the 15 degree air. The humidity was high enough to see your breath so any more than a couple of shots were inducing nasty mirage. I simply sighted the rifle in with a new scope using another load, let her rest 5 minutes, let her buck with a fouler using the 200 eld-x/rl33, then went to work on the group...
I'll now load a few boxes of the load up and wring her out for average accuracy and load performance. I already know this pipe likes the 180 hdy interlock so the 200eld-x would have actually surprised me if it sucked.
I need a box of the 212's in 30 cal. and a box of 175's in 7mm to wring out a couple of other pipes.... It's game on for Hornady.
