Re: H4895 for 308
4895 was the long-time military powder for LC Match ammunition in both the 30-06 and 308 Win/7.62mm loadings. Extremely good accuracy and temperature insensitive enough to pass all the military testing requirements, no problem. Don't sweat it, it's great stuff and a perfcet choice for this application. Back when the M14 was the dominant rifle at Camp Perry, you could poll the shooters as to what load they were using. Guarantee you that 95% or more were using about 41.0-41.5 grains of 4895 under a 168. No such thing as load development there, and if your rifle didn't shoot this load, you had a gun problem. Had great results with both IMR and H versions, and they're all but completely interchangable. Works equally well with the 175s as it does with the 168s.
