I used them with subsonic loads and the worked fine. If you are loading max loads I would use a rifle primer. The issue with pistol primers is they are usually softer and the pressure could cause them to come unseated when fired and get stuck in your gun.

No reason to specifically use pistol primers over rifle primers, no. Since the vast majority of shooting I do with my 300 blk is subsonics, I use the cheapest SR primers I can find.

Just an FYI, pistol primers in .223 is a really bad idea.

Load wise I would guess they'd be fine in the subsonic loads but it all depends on pressure. I would just go with the recommended primer.
It's not like they're cheaper so what are you gaining? I also wonder if there is any slam fire worries with the pistol primers??? |

As stated I am sure you already know but just be very careful about making sure they dont end up in the full power rifle loads. |

A very bad idea to use pistol primers in 223 or 300 blk.
Doesn't matter if someones gotten away with it, a bad and dangerous practice. |

I've only used them once. H110 loads. Per the reloading info the pressure should have been below that of .40 S&W or .357 magnum ammo - but the primers still had holes in them anyway.
That didn't happen with the same loads when using Tula small rifles primers or Federal small rifle primers. I haven't used small pistol primers since for .300 BO since. |

The only time I've used pistol primes in 300BO is with non-cycling 155gr. AMAX bullets for a break open rifle. I was using 7.7 gr of Unique with pistol primers and they worked just fine. Again, these were no-cycling. I'll still make some like those to mix in with my regular subs for malfunction drills.

I tried the pistol primers, and the results were not good. I loaded ~20 to compare accuracy, about half of them pushed the primers out and left heavy extractor marks. There was no improvement in accuracy and nothing to gain. You definitely want to use intended primers only
