and ALL over the place at 100 yds
14in high, 12in low, 8 left, 10 right, and everywhere inbetween
WTH is going on?
the particulars
50 cal cabelas Haken Open Sights .495 hornady rd ball .015 pre lubed patch 50grs of Pyrodex RS Musket Cap Shot from a pile of sand bags front/rear
upon inspection of the patches it appears about half of them are blow in two. the ones that didn't blow apart are pin holed around the outside diameter of the ball most at or near were the rifling's are seen engaging, also the rifling's don't look to be cutting the patches uniformly some look to engage fully while others shown little if any engagement.
This was the first time I had shot at 100yds I have been doing LD at 50 and thought I had it figured out
I wouldn't be able to hit a car let alone a deer of elk consistently with it patterning like this

after rereading sounds like the patches are almost donuts, this may be caused by sharp rifleing or to much powder. still check the balls for consistantcy first.
you may try .10 thousandths patch see if it helps. you are a little over sized with combo you are using.
my first guess would be bad lead/molding I would try a few back at 50yd to see if still good.
I don't lose accuracy at 50 yds between 50-100 it goes the hell

Didn't think to do that, on the to do list

patches are blowing apart nearly in half, half of the center is still there along with half of the overall patch, I reduce the load from 60grs to 50grs and the patches stopped blowing apart but I am still seeing pin holes were the rifling's engage
I picked up some pillow ticking that should be .09 and will get back with the results
I had being doing LD at 25-50yds where I consistently was getting 1"-1.5" groups I'm glad I decided to see what it looked like at 100 this would have been disastrous come hunting season
Thanks
Had the exact same thing. Then I read about stuffing 1 patch down on top of the powder, then the patched ball. It was called "double patching" altho it does not mean putting 2 patches on the ball...as stated the first one went in on top of the powder. I actually use thin old cotton cloth (okay....old washed cotton boxer shorts was the source, like I said, I needed thin material) about 1 1/2" X 1 1/2" and I crumple the first one up so the ramrod does not pull it out after I seat it on the powder. Then load the patched ball like normal. The author (Sam Fadala) of the article actually used material from an old paper hornets nest! You know, those football shaped things hanging in the tree. Since I dont often find those I just used old thin cotton clothing. It worked perfectly for me...groups tightened right up and patches were not blown through. Also, I used .495 ball plus 0.015 patch like you, but my plinking load was 65 gn RS and my hunting load was quite a bit higher. the double patching helped both loads.
Will try the double patch along with some different patch material
I would go up in 10 grain increments until I got to max. just to be sure.
If the rifling is ruff the rifle should still shoot accurately especially if it shoots 1 inch at 50 yards. It should be more consistent than that at 100 yards.

This may not help much, but then again, food for thought never makes your stomach ache.
At closer ranges I have noticed that this is not AS important to keep track of, but, when you start moving the target downrange, the consistency of the load AND the pressure with which you compress your charge also becomes very critical. IF you have a routine and even have a kadooty (fancy loadin stik) you can get the same pressure on the load every time...if not it takes some playing around with and lots of practice.
BTW, if 50 grns is your test load for hunting, what muzzle velocity and energy are you putting out? If you can meter this with a chronograph you may see the variation. Beware that a lesser charge may sometimes mean more accuracy, but it may be losing umph downrange to efficiently kill your intended target.
Best Regards!
I had about the same problem with my .54 cal. The patches were getting a big hole blown in them. I finally tried a wad in front of my powder and behind my patch & ball. Mine went from several inch groups at 25 yards to one ragged hole. It might work for yours Odawgp...good luck...bull
Exactly, this is what happened to me when I double patched. The first patch, or in your case the wad, protects the patch around the ball from the gasses and from tearing. Odawgp's problem isnt too little powder or a rough bore, it is his patches are not holding up. My Green mt barrel is 15 years old, has over 1200 shots thru it, and STILL tears patches unless i double patch.
That is helpful to me as well. I think I have a barrel that is cutting patches probably because of some corrosion before the gun came to my possession.
Mine is brand new with only 101 round balls down the barrel
I had excellent accuracy at 25 and 50 yds thought Id at least be on the paper at 100
WRONG!
