Little Help Needed Please

[Terrier]

My 40 SMR has a Rice barrel.

 

[French Colonial]

Are the barrels not marked on the bottom flat with the makers name? Mine were.

Shot my new Kibler Woodswalker in .50 for first time today.
Used Hornady .490 balls, Ox-Yoke .015 patches lubed w/Mr. Flintlock.
Tried 3 shot groups of 50, 60, and 70gr. of 1.5 Swiss, all primed w/4F. I swabbed after each 3 shot group.
Ignition was not instant, had a slight delay, was picking vent after each shot.
Groups were all shot at 50 yards. Smallest group I had was 3", others were 4-5".
Pic of some of the fired patches I found.
Looking for some help reading patches and suggestions for better ignition and accuracey.
Thanks in advance!

work powder charge up 80 90 100 110 (swiss 1.5) before doing anything else (powder size), 5 shot groups.
for better ignition: (in pan) more powder less powder right bank left bank keep shooting her and you'll find her sweet spot. you need to shoot her 200 x's

My Kibler SMR 45 and Woodsrunner 54 are both Green Mountain.

I agree with the others that said to go with 3f powder and .018 patches, and even possibly going to a .495 round ball with the .018 patch. In my .54 cal. Woodsrunner I had to go to a .535 round ball and a .018 patch because I was getting patch results like yours with a .530 round ball and .015 patching. That fixed the patch problem and tightened the groups.

I thought when you ordered from Jim that you could choose the barrel you wanted,..
Not so?

Incorrect. Jim gets his Woodsrunner and Colonial barrels from GM.

At 40 grains the ball would bounce off an animal and hit the OP.

Safety First.

Grab some 3F and work up from 50 to 70 grains.

Go with 5 grain jumps until you find the sweet spot in that barrel. 5 to 7 shots per jump. 25 to 35 balls. 3 shots does not a group make.

Keep a log book and document everything.

40 grs FFFg is great for paper targets. Easy to shoot for beginners. Recoil is minimal.

Ditch that 1.5F Swiss. I had some of that

Amen, Bro. I had some once and it almost needed a hot railroad flare stuck in it to get ignition. I posted a thread on it sometime back in ancient times. You might be able to find with a search. Try 3Fg, there is a reason why it is the most used granulation.

Many great pieces of advice above... I would add 1 thing. after you shoulder it and before you cock the hammer, give the lock side of the stock a light thump with the heel of your hand. levels the powder in the pan and tilts it slightly away from the touchhole causing the flash to flare towards th touchhole while driving a grain or two into the backside of the vent.. works for me, might help with that delay.
just an opinion Legion

Has anyone had to open the vent hole up on a KIbler GM barrel to the 1/16" suggested?
Again, I really appreciate all the feedback.
thanks all!
