Accuracy trumps.


Yup. I wouldn’t expect RL26 to be the scnizzle but any 4350 variation would be a good place to start and likely end. I would avoid most heavily coated ball-type powders if you don’t want a flare gun effect. (Perhaps Hunter or Big Game would be an exception. I dunno.???)

Sometimes, the air you 'let in'matters less than the air you 'let out'.
