Thread: 308 brass to 7mm08

Again from memory this appeared in Rifle or Handloader Q&A column many years ago. I know that target shooters often use the small primed cases but these are not generally shot in the same conditions. I don't remember what the powder was which could be important.
GPM.

my understanding is if it sparks it should bang, but a matter of slow or fast, sometimes under extreme cold even the lrp could not deliver the speed, thus the magnum is handy.

Where are all these plenty of LR primers? The Fiocchi shipment was gone in a flash likewises any stock my local gunshops get in.

Sizing 308 Palma down to 708 can be done, no issues at all. Zimmer is correct, if SRP does not work in a 308 there u something else wrong(in most cases the shoulder has been pushed back to far.

Shout out if you cant find Palma brass. Ive got some Lapua Palma SRP brass(new).

Under extreme cold other things could come into play eg sluggish firing pin release due to dirty of overlubed bolt internals.
Without more specific info on the failure to fire we can only speculate.

Jonnys reloading bench on YouTube done a bit of a unscientific study on the srp thing after he found himself getting hangfires
And found that powders with poor case full was the culprit when using powders which filled the case it was no issue
But poor casefull powders were pretty consistent on hangfires and from memory he had a couple of missfires also
