I know some guys use small rifle primers,I've never tried it.

I would not use the small rifle primers. I have seen SP magnums on some of the online sources lately. Of course there is the hazmat thing.

I need 100-200 primers, so it's not going to become an order.

Personally, I would not light H110 off with anything but a small pistol magnum primer

Magnum rifle primers are much harder to withstand greater chamber pressure so there is more possibility for a misfire in revolvers with light actions.

You might want to finish filling in your profile so that we know where you are referring to when you say "none to be found locally"

If you are in South Florida, I will help you out. I have ~20k of small pistol Magnum in loading room right now

If you are not in South Florida, I am sure that there is someone in your neck of the woods willing to help

Besides, to re-develop a load for one or two hundred rounds of ammunition on a temporary basis is a bit of work.

As mentioned you can try small rifle primers. They will probably ignite the H110 OK, but again your guns firing pin may not set them off.

It is not the recommended primer.

Or you could change powders if you have anything else like 2400

I use Small rifle primers in all my 38/357 loads, never had a problem,the Rem 6 1/2 match rifle work great, followed by the Federal SR match

I would try the small rifle primers just to see what happens. I tried some Rem 7 /12 primers in a pistol load and had problems getting them to light but other than that they worked OK. Of course, I use them in my 454 Casull loads, but that's what's expected.

Considering Remington recommends you use their 6 1/2 primers only for the 22 Hornet and Magnum handgun ammo it's probably the perfect time to use them up.

Of all the primers you listed I think the Rem 6 1/2 primers will be the choice.

I've used a CCI-400, instead of a CCI-500, in my 627 with 14.0gr/2400 & 158gr XTP, just fine. This is not a max load but your load, 13.5gr/H110, is. In fact it's above Hornady #8 using the same 180gr XTP bullet. I'd drop your charge down a bit to use with the SRPs, just in case to avoid any pressure issues.

An old CCI Energy Primer table placed the CCI-400 & 450 in between the CCI-500 & the CCI-550, in terms of ft/lbs. of energy.

I have chronographed identical loads, except for primer, side by side
with Winchester SPM and SR in the .357 magnum and found them to
give almost identical velocities. I have never had a SR fail to fire. I've
also tried Rem 7 1/2s and CCI 400s in lesser quantities but experienced
no misfires. A local shortage of SPM primers prompted me to buy 5K
Winchester SR primers for future use in the .357 mag.
