27.3 h4895 is shooting great with the sierra 60 hp's but only 2935 fps. Shot good at 3230 with 27.3 2200 and 55 varmagedon but groups fell apart recently.
I cleaned it today and it is still liking the h4895 60 hp load but I probably need to try 2200 and the 55's again.
I shoot 55 gr. Nosler ballistic tips in my 6x45 pushed by 24 grs. of IMR 4198 to just under 3,400 fps. This load is safe in my rifle but I can't speak for anyone else's.
Im not sure if h41898 is similar to imr 4198 but I will probably start in at 22.5 grains with 60s and 23 with 55s. I saw where someone was loading 25 and I thought that sounded a bit stiff. I just didn't find much information and wanted to make sure I was in the ballpark. Thanks!
