I have been using 2F powder in my .54cal flintlock rifles (T/C Hawken, Lyman GPR and my new Kibler Woodsrunner) for 30yrs. I did this because, this was always recommended in rifles over .50cal . My understanding for this was, because 3F powder created very high breech pressures. I'm told that modern steel barrels can handle the pressures. The upside being, you can use less 3F powder to get the same velocity as 2F and thereby save money. On the downside, I'm wondering if the 3F produces more kick or a lot more kick. Anyone have any experience or knowledge of this?
