Is it possible that the Federal case neck was long enough to protrude into the forcing cone, squeezing and holding the bullet long enough so that excess pressure was produced before it was released?
How about the bullet being jammed into the forcing cone as the round was chambered,once again producing excess pressure on firing?
Measurements of the new Federal cases and bullets might be interesting, but might not show the same dimensions as the "problem" round.
The only other possibility that comes to mind is too much powder, or the wrong type.

Someone on the Accurate Reloading forum thought the throat might be too short and suggested checking it with a bullet seated base first?

Either the throat too short, the case neck too long, or a bullet profile not compatible with the throat sounds like the most likely cause to me.
A quick test with the new Federal ammo would be to simply chamber the rounds, note any unusual force needed to do so or close the bolt, and finally, note the effort needed to extract the un-fired rounds.

Will test and report back when the new rounds arrive.
The Remingtons were 250gr. round nose soft points, the Federals were 225gr. Trophy bondeds which are spitzers.
thanks,
Rob

vangulil, Usually, if I'm checking for some interference, I find it easier to "smoke" the neck/bullet with a lighter or candle. This gives a better view of the areas of interference. Mike

Mike Sounds like an excellent idea. I have a situation myself where it should prove helpful. Highly recommended for the OP.

you can "smoke" a case with a Sharpie or Dry Erase marker if you don't have a candle.

I'd also consider checking the Rem's. I'd struggle with the confidence if I were to stick another Federal in, but chances are, the blow up was a one off. I'd think the replacement cartridges would be in spec.
Early on, there was a mention of a neck split on the good ones. Maybe take a careful look at the other necks and make reloading adjustments if needed. Just thoughts.

Yes, one of the 40 Remington factory loads had a split neck.
Would a chamber cast be of any use?
