That 45gr. H4895 works well in a 90 to 98gr. capacity case as well, with 500gr. bullets too. They ran 1,540fps and were quite safe in my 1871/76 Mauser (re-chambered to .450 Akaskan). The pressure is very low as the load was listed (somewhere) for moderately strong .45/70's at less than or around 24,000psi. I cannot find that exact data now, but it certainly is safe in any M86 Winchester or stronger rifle, even in the short 2.1" case.
