I have used several thousand Rem 1 1/2 primers, and now it has been pointed out that Remington's disclaimer suggest not using these primers on 40 S&W loads, and the same for 357 mag. and 357 sig. I can understand the 357's, but 40's?! :confused:
Going through my notes I see that I have about 400 reloads in 40 that I didn't note which primer was used. Almost all using Titegroup on Berry's plated. About 50 using Autocomp with plated.
Is this something of great concern? Or something to watch with the slower burning powders?
The loads are on the high side of medium from the Hodgdon load data.

Thanks for any light that can be shed on this!
 
Plated and slow powder would seem to produce lower pressure than jacketed & fast powders. Just watch for pierced primers & damage to the firing pin nose when shooting. If the primers fail, pull the bullets and change the primer.
 
40s re considered by some to be high pressure rounds. Remi 1 1/2s are considered by some to be low pressure primers. Remi is the one footing warrantees. Maybe they know something.
 
Okay, thanks! I'll watch closely.
I went over the disclaimers for CCI, Federal, and Winchester SPP and didn't see anything about 40 S&W.

rogn, 9mm are just as high in pressure, even higher in +P. Or is this because of the energy difference?
 
The Hodgdon site lists primers used. Only the 357 mag is using a mag primer. 40, Sig, are using "Primer: Winchester SP, Small Pistol " Same clasification as the Rem 1 1/2 primer. But then, Remington should know best??
 
I'm still learning and wouldn't want to have a bad surprise. Thanks 243 & rogn. It'll be duly noted for future reference.

Not necessarily... Remington has a small rifle primer they recommend for the 22 Hornet ONLY. (Rem 6 1/2) They recommend their Bench Rest SRP for everything else and they also call it a magnum strength primer. (Rem 7 /12) That makes no sense to me. If you're going to produce a standard SPP and standard SRP make them to the standards that can be used safely like all the other companies do. Unless you read the fine print it's too easy to make a mistake and when loading ammo mistakes can be dangerous.
 
I contacted Remington a few weeks ago on this.
In their warning they specifically call out 40 S&W and the 357 Mag and SIG. I asked them why and they told me these are high pressure rounds and not to use the 1 1/2 in these high pressure rounds.

I then asked if this warning included the 9MM Luger as it runs at the same pressures as the 40 and 357 Mag. Their reply was, "We use the 1 1/2 in our factory 9mm loads". Go figure.:confused:

I have contacted Rem in the past on other discrepancies like this and it is not uncommon to get different answers from different techs.
 
So in future purchases, if given the choice, I'll go with another brand of SPP. Besides, Remington usually run a few more dollars per 1000 than the others.

According to Lyman 49th.9mm pressures range up to 32KPSI, the 40short and weak is up to 24KPSI(although Ive seen higher listed elsewhere), while all the other small pistol set outside of the 357 seem to stay under 20KPSI. Iguess Remi makes a soft SPP for the older low-pressure guns, with gentle mainsprings. The 6 1/2 is stated to be the primer for the 22 Hornet. Why they do this I don't know. The primer issue extends further such as the caveats with the AR family of rapid bangers. There is some history of premature ignition. Blamed on primers-Federal tends to get that nod. AACD, the whole reloading/handloading arena is fraught with hazards H110, N110, IMR 4756(?), 4759(?)(IIRC) and I think there are a couple of other close calls out waiting for us.

I think you are mixing CUP and PSI together. They are mutually exclusive and not interchangeable.
 
I am going on two decades of reloading a bunch of 40S&W (mild to full power) using various powders and primers.

I never used Remington primers but used CCI/Fiocchi/Magtech/PMC/Tula/Winchester SP primers without pressure related issues (and PMC brass cups are really soft).

I guess if you are concerned, take Remington's recommendation and use other brand primers for 40S&W. :uhoh:
 
^^^380 Auto, 38 Spl. , and 9mm.^^^

According to my notes, most of the reloading for 40's used Federal 100.
Got slack on listing primers. Another learned lesson, hopefully!
