I've only seen one test of the two over a chronograph, that yielded an 32 fps slower reading for Fg over FFg. Hardly worth consideration.
 
Just seems way more consistant than the 2f I had been using.

Well that's the bottom line isn't it? If it works better with load X over other previously tried load combinations, then use load X. :grin:

MV's may be deceptive. While the resulting MV might be less than 50 fps slower between 1F vs. 2F, the MV will not account for the acceleration rater to reach those muzzle velocities. So yes the kick may be perceptibly less..., who knows maybe it's not the load but your comfort level, and as such your body isn't anticipating the recoil as much or at all, so you simply shoot that load better? Again, no need to argue with success, do what works.

One thing to focus on with 1f. Yes it does produce more fouling. If your lube results in hard fouling that interferes with loading, you're using the wrong lube.

The fouling should be soft so that it shoves right back down the bore as you easily load the next charge. Olive oil or bear oil have both proven good for me.

I've never experienced any ignition problems for that fouling going back down the bore, mostly I suspect because it is pushed back down ON TOP OF the powder charge rather than around the vent or nipple. Then it's launched on the next shot as that one lays down a new layer of fouling.

You're mileage may vary of course, but for me any extra fouling is a non-issue, right there with any loss of velocity from the slower burn.
 
I haven't done a lot with shot in my smoothbore but have launched many a round ball. More than just one load has proven quite decent, but the load I settled on uses 3F. Once I get back into shot testing, I'll try some 1F with that and maybe prb.
 
Now you guys have me wondering if I should change to a coarser powder on my 54 smoothie. I usually shoot 3F in everything. Going to our club Rondy this weekend, taking all rock locks. I didn't plan on using 2F, better put some in my box for this weekend JIC.
 
As a general point.

1f burns more slowly than 2f and produces a gentler pressure rise with a lower pressure maximum so it is gentler on both the gun and the shooter. My guns are antique 19th century ones and I prefer to use 1f simply to strain the poor old things as little as may be necessary.
