I am a dinosour and have tried ball powders bak in the 60's ,,,I admit all powders are better in these modern times,,,howeve ball powders usually gave more velocity but less accuracy and the labs and experts say less bbl wear (longer bbl life) ,,,,I used 414-450-335-etc in various varmint cals,,,today I have used CFE-223 in rattle guns with good accuracy (for a rattle gun) and it cycles reliabley,,,,it is in the burn range that will work in BR's with light bullets so I am hoping to try it now that good weather is here,,,ball powders have a reputation for being sensitive to cold temps becuse of the deterrent coating used to slow the burn down at first because of the large surface exposed at first and usually requireing a mag strength primer,,,so I have rambled along to say I think "we" need to re-visit modern day propelants to re-prove the old wives tales once again,,,Roger
