I am still testing this powder but have found it to be easy to work with so far. Test gun is a new ruger mk77 Varmint/target rifle, in 25-06. Vey nice chamber and a short throat. All brass was prepped and neck turned. 100 Sierra bthp MK 62 gns went 3457 No pressure signs at all. groups where not bad. These where seated just off the lands .005 have more that are seated in .005 incrments, as well as other bullet types nosler and Hornady. Well update as i test. Great velocity with this powder.
