That's what the label says. I used them for F class and they did fine in a rifle.
But that does not say what it IS as far as cup thickness, amount of mix, anvil location. Is it physically a small rifle primer or a small rifle magnum primer? Probably not a small rifle military (41) primer.
I just posted a test on using small rifle primers in the 9mm.

Atlas Gunworks posted a video on SPP comparisons with Rifle, Small Pistol, and Magnum, results were no negligible difference:

In another forum, people are asking about using small pistol primers in rifles. I guess I'll try that next.
