So I'm having an issue and I need a little help in figuring this out. Here's what I have......Rem 700 Sendero in .300WM with XLR chassis system and DBM. I have been reloading for this rifle for about 2 years. Using the same load I have not had any issues until now.
I recently bought new RWS brass and have only used about 4 rounds from this batch. With this RWS brass the spent casings are jammed in my action. Never had this problem before with the old brass I was using. The old Brass was a mix of Federal and Winchester brass.
My reloads are as follows:
Powder: RL-22 with 68.2 grains
Bullet: Hornady 208g A-Max
RWS .300 win mag brass (never fired)
Primer: Federal No. 215 LMR
C.O.A.L.: 3.4500"
My question is how come with my old brass I was never getting the jammed cases, and now that I switch to a "top of the line" brass, I am getting stuck cases? Am I loading too hot....I am getting alittle pressure signs with the RWS brass with flat primes and action marks....but again I never got these signs with the old brass.
Also could it be that I developed this load in the winter time and this is when I was doing the majority of my shooting? Will the temperature play this much of a difference? (I know it will play a factor, but how much?) Also, was it that this load was too hot to begin with but the cheap brass wouldn't give me any signs?
Any help would be greatly appreciated!! Thanks all.
