    I had a question regarding the small primer 308 brass from starline or I guess any brand using that configuration, it says to use a cooler temperature primer/powder to prevent hang fires but I’m not sure what that are looking for.

    I’ve got a pretty good recipe for LRP but not sure if the same recipe with SRP will work, and before getting more of the same powder I figured I’d ask for advice.

    This is from their site
    “As with all types of cases this large with small primer pockets, it will require care in powder and primer selection in cooler temperatures to prevent hang fires. Single-based propellants are generally easier to ignite and a quality primer such as the Remington 7 1/2 BR are recommended.”

    I'd just picked some up due to LRP's being pricey / hard to find right now . Have both the Rem 7 1/2 & CCI 450's . Read an article on UK Targetshooters about SRP performance in 308W Palma cases . I live 60 miles east of Mobile , AL , so if it's too cold for SRP you can bet I aint gonna be out in it . BTW interesting that in their test the Magtech 7 1/2 SRM had the lowest ES / ED . Figure I'd stick with extruded & mag primers , whichever gives best results .

    Sorry to revive an old thread, but due to primer availability I decided to try the Starline SRP brass and use CCI 450 primers. I just wanted to do some velocity ladders. I had 2 failure to fire primers out of 25 rounds. Good primer strikes on both. This is a GAP Crusader for the rifle and was using Varget. Anyone have any ideas? I may try CCI 400's but thought I would ask.

    That’s a definitely a bit odd, I’ve got probably close to 500 +/- a few with the 450’s without any issues. Are they older primers that might have gotten the primer compound knock out of them? I know it can happen with rimfire ammo if it get knocked around a lot, but I’ve never personally heard of it happening with normal primers.

    They probably are a bit old however they are stored in a very low humidity and stable environment. Same primers from this same 1000 have worked well in my 6.5 srp brass. I'm stumped. One BR guy at the range said it may be due to using new Starline brass and being very undersized or SAAMI spec brass. I don't know though!

    I never thought about the brass being a little short and not allowing for a solid primer strike for ignition. I know I’ve had that happen with my dasher when I was figuring out the length I needed for a false shoulder but otherwise it’s not something that would cross my mind.

    The way you put it was exactly what the br guy thought! He figured once fire formed it should be fine. He recommended loading to the lands to prevent it, or something along those lines.
