6.5 carcano

[jmoore]

Its been found that reducing charges of slow burning powders can lead to wild pressure swings, sometimes resulting in burst actions even w/modern magnums. (Treat this round as a mini-mag throwing crazy heavy bullets for it size.) On the other end, I suspect that the long bearing surface and high engraving forces required due to the deep rifling can create high pressures. Hornady put forth a lot of effort to make this round work as intended, so I'll defer to their expertice! Plenty of other good stuff in the new manual; its well worthwhile.

It might be worth getting in touch w/ Hornady direct to see if they even tried the powders that are more available to you. If it wasn't suitable, no data would be in the book but there may be records showing it WAS tried. On the other hand they may not have gotten to your stuff (only so much time to put into a "fringe" caliber!).

Thanks jmoore, I will try an e-mail, but I will also get the book, as I now have 3 types of "problem" rifle which go best with the Hornady long bullets: the M91/41, the Argentine 1891 Engineer's Carbine, and the Enfield No1 Mk V.

You'll probably blow up a couple of hours when you get it just sniffing around for the new info you didn't even think needed! I discovered that the light weight bullet loads have increased dramatically in 38 Special . Iwondered why bullets used to keep getting stuck in the barrel, so I quit trying for several years, then, voila!, Hornady up the loads! No more problems....

There have been several reports of blown case heads with the Hornady .268 bullet. I would be very hesitant to use a bullet for which there is only one safe powder combination.

[jmoore]

There's more than one powder listed! You just can't substitute other components willy-nilly. Hornady ran these loads up to full military spec (or a tad more) with the understanding they ought not be fired in crap rifles, which, unfortunately, are rather common w/ Carcanos.

Yumpin' Yiminy! They did use a great service, which the idjits will abuse until Hornady won't stick their neck out for us any more.

If you reload too, prehaps its time to invest in some new manuals.

[ireload2]

I think the latest information on the .268 bullet in the Carcano only lists the 760/H414 combination.
No thanks!


Link to other posters having problems with the Hornady bullet

The poster mag seems to have used a lot of them in a lot of rifles and has a handle on the problem.

[jmoore]

Incorrect, sir!

Again get thee to the manual and quit relying on internet gossip.

Those having problems in that thread all are going outside the bounds of the recommendations and trying to wing it. Mind you, its always best to work up to a max load for YOUR rifle. Yadda, yadda.

Hornady lists six SUITABLE powders W/ two FAVORITE powders.

This is getting old. I'm done. goodbye.

[ireload2]

All manuals are obsolete when printed.
How can I possibly be wrong to advise extra caution?
Even Dave Emary of Hornady had problems with the .268 Carcano bullet.
See data here

I have both Italian ammo and US made ammo (WCC headstamp) and both have bullets that measure about .266.

Gee, if he had so much trouble, why did he LATER publish finalized loads in the NEW manual??? (Sorry, couldn't stand it any longer)
