I am having problems getting my new LRH to fire. I am using hot primers (Remington STS, Federal 209A, CCI 209M) and 120g of BH209 with a Barnes 290g TMZ. I use firm seating pressure with a range rod. I have tried the red plastic jackets and the nfpj breech conversion. The primer goes off but the powder does not ignite. Any suggestions would be appreciated.
