460 and 454 casull primers

[TLDELL]

I just bought a 460 mag and am starting to handload it. Was wondering can you get away with using large pistol primers in it since there are no large rifle primers on earth

I have no experience with that loading.

From your question, I'd say that you're probably new to handloading.

Don't mess with the recipe.

I wouldn't. There is a reason why large caliber pistols use rifle primers: pressure. That should be enough to scare you.
Even if that would not be an issue, large pistol primers are usually shallower than rifle primers ( cup thickness)
Less igniting power as well.

Been doing this 40yrs but this is my first time loading above 44 mag so i am being cautious.

I think (don't know for sure, won't know until home Monday) I have a couple hundred large Remington large rifle primers.

I would without a doubt.

I had some cci large rifle for sale. May have taken it down though .

Large rifle primers are recommended for loading the S&W 460 mag. The problem exists where the depth of a LRP is .125"-.132" . The depth of the LPP is .117"-.126" . You can observe light primer strikes (possibly pushing a LPP primer deeper into the primer pocket) if you attempt loading using LPP's . I experimented loading with very carefully seating LPP's in my 460 XVR and did not have any light strikes, but I would not recommend doing this practice.

If the primer pockets are made for rifle depth primers, then use rifle primers. I see large rifle primers in stock online.

I've been getting alerts on most all primers in the last few weeks
that are in-stock.

I also got a 460XVR and am debating what I'm going to load.
I found the S&B 460 ammo for around $1.30 each which is around what
454Casull. 454 uses SRP and 460 uses LRP{M}.

I may just load 454 fairly hot and buy 460 when 'needed'.
Similarly I load 44M both slightly warm and fairly hot so I dont need 2 die
setups or adjustments.
