toddpipkin Posted October 23, 2008 Report Share Posted October 23, 2008 I have now have my new T-C Omega Z5. I plan to shoot the 250 gr. Barnes Tipped Spit-Fire MZ bullets. I have tried the new Blackhorn 209 powder. It's GREAT; I will continue to use it!! With powder and bullets being so expensive these days, I hope to learn from the experiences of others. If you have shot the Omega / 250 Tipped SpitFire / Blackhorn combination, would you please share the amount of powder that you found to work best? Please be sure to make it clear whether you measured the powder by volume or weighed the charge on a scale. Quote Link to comment Share on other sites More sharing options...
AJ Posted October 30, 2008 Report Share Posted October 30, 2008 I have been shooting the 290 gr TMZ with 85.2 gr by weight of BH209 and a Win 209 primer. I get MOA groups out to 250 yards. At 300 yards they open to about 4". I like BH209!!!! Quote Link to comment Share on other sites More sharing options...
toddpipkin Posted October 31, 2008 Author Report Share Posted October 31, 2008 Shot mine with the iron sights at 100, got @ 3" groups with these old eyes at dusk. That was with 70gr. BH 209 by weight, and with 75gr. and 80gr. Could definitely tell the difference in recoil and velocity at each step! Got my Nikon mounted today, can't get to the range until Friday. Since the BDC reticle is calibrated for a 150gr. (volume) load of true black and most bp substitutes, and BlackHorn says that 120gr. (volume) of BH209 is equivalent to 150gr. (volume) of those, and BlackHorn also says that to convert volumetric charges to weighed charges, use a multiplier of 0.7..... The first load I am going to try with the scope is 84gr. (weight) of BH209. I'll let you know how it does. Quote Link to comment Share on other sites More sharing options...
