TRDFurgesson Posted March 23, 2012 Share Posted March 23, 2012 I have lots of bullseye. 180gr HP data from Lyman calls for a max of 5.7gr. Alliant 180gr HP max load calls for 5.5gr. For a factory load equivalent what do I want to use for this 180gr TN FMJ??? Thanks, Bobby Link to comment Share on other sites More sharing options...
kenv50 Posted March 27, 2012 Share Posted March 27, 2012 I shoot all types of 180gr Zeros. 5.0 grains of Bullseye will product muzzle velocities in the 954 to 974 in a ParaOrdnance 16-40 and about the same in my Glock 35. This gives you a healty power factor of 171.72 to 175.32. I live in Georgia and always worry about how temp may effect bullet velocity. So having the safty margin of a power factor in the 170's is fine. Ken V Link to comment Share on other sites More sharing options...
