Primer Quality!

I too had some failures with Tula. Several hits failed to ignite.
The only difference in CCI, Federal, Winchester, S&B, etc is that Federal Small pistol are the most sensitive, S&B the hardest, and Tula the hardest seating.

I did have two lots of Winchester Large Rifle that blew out in the edge, but have discarded all of those and swore off Winchester rifle primers.

But, generally, primers are some of the most reliable consumer products.

Winchester replaced my bad LR primers with a new batch for free including shipping. Even offered to replace the bolt on my rifle due to the gases marking the bolt face.
