so hows a triple 7 209 primer diffrent from other primers? I use cci magnum primers with triple 7 powder. should I not be doing this?dce said:The blackorn is great.I can shoot all day and each bullet goes down as easy as the first one with no change in accuracy or poa shift.You have to use an oil based solvent to clean,like Hoppes but it cleans up easy.The flashpoint is higher so you can't use triple 7 primers.I just use regular CCI's.
Blackhorn is more expensive than 777 loose powder but you use less and you don't have to use more expensive primers.It's definately cheaper than shooting 777 pellets.The only drawback is availability.No one carries it around here and it would be expensive to have shipped.I have a buddy that drives by Cabelas quite a bit so he stockpiles me whenever I need some.
i purposly got the cci magnum primers so it will shoot hot every time. I get a little crud ring starting after a few shots with the triple 7 pellets but that hasnt effected my acurracy.burk313 said:The triple 7 loose powder used with shotshell 209 primers was causing crud rings in the barrel and manufacturers doing testing found the shotshell primer was deteriating accuracy so manufacturers started producing special low power primers which made better accuracy behind triple 7 powder..The Blackhorn powder you MUST use regular full power 209 shotshell primers because the flashpoint is higher.
