Re: Barnes 175 LRX loads for 300 RUM
300 RUM, Rem M700 (26" barrel)
175 gr. Barnes LRX
CCI 250 Primers
Retumbo Powder - I think I started around 94 gr and worked up to 99.5. Primers were pretty flat at that point and I was getting extractor marks on the brass. Settled on 98.8 gr of Retumbo for a velocity of 3400 fps.
Hope that helps.
