An interesting mistake
 Today was too nice not to shoot, but the snow was nasty. Before I could walk on the crust somewhat, but with the warm spell it was sink city. Every step was down in the snow past you knee. So I went only to the edge of the back yard this time and that is 35 yards. I decided that since it was that close of a target I would shoot something traditional and open sights. I decided to shoot a Traditions Woodsman Hawkins. Rifle: Traditions Woodsman Hawkins percussion lock 1-66 twist open adjustable sights. Powder: Goex 2f Primers: RWS 1075 Projectile: Lee mold .490 pure lead home cast roundball Weather: 45º (hooray no jacket needed!!) overcast and calm I got out to the shooting table and like always forgot a lot of stuff. I forgot the see through powder measure in the house. Being too lazy to go after it I took a brass hunting measure out. It was one of them you pull upward and each notch is supposed to be 10 grains. Well I wanted to shoot 75 grains for starters and see how this shot. So I shot off three with that powder charge. I was shooting home cast roundball and moose milk pillow tick patches. I was surprised they were hitting so low. So I jumped the charge to 85 grains of powder and shot three more. Again, still low. I had forgot to take my notes on this rifle with me, and I thought this was a 85 grain rifle. But I decided to go upward in the powder charge. So I pulled to what I thought was 95 grains of powder and shot several roundball. The group was good and so was the POI. So since I had to go in the house for more coffee.. I brought back the see through powder measure. Imagine my surprise when I poured a brass open measure into the see through measure and it read 105 grains of powder. I had noticed the crack of the rifle was good and powerful, but the recoil was nothing special IMO. This little rifle with the slow twist is an amazing roundball rifle. I later checked my notes and it says 90 grains of powder for this rifle. It now also says.. up to 105 grains of 2f Goex. |
wow that round ball was moving and good accuracy also..Great shooting.. Ray

Boy Howdy! that is some good shooten! I need to get out and do some shooting but can not fond the time right now.... |
Nice shooting. I think too many guys underestimate how accurate a slow twist barrel can be with a PRB. You can get those same results at 100yds too.
The problem I have with the PRB is it loses so much energy at 100 yds. Otherwise i'd never shoot an inline. |
same way my traditions kentucky flinter is, a huge powder pig. Mine wants 110gr 3f goex. That one does have some sting to it though.
|
I have three of those TC U-Views and find that they all throw light charges.
Using GOEX FFg as a base, one would expect a 100 grain measure to throw a 100 grain weight charge. However the U-Views average around 90.5 grain weight when set at 100 grains volume, filled to overflowing and cut off without a tap down. Tapping down the initial fill and topping it off again before closing the funnel yields a charge of about 94 grains weight. |
That's a dandy mistake. Good shooting Dave.
|
Good shooting. Not all mistakes are bad.
|
Awesome shooting there, it seems with Goex and other real blackpowders you can get away with a little goof. The new powders out there could send you to the ER if your not careful. By the way it was 82 here today in Missouri.:happy0157:

That is if you remember to put any powder down the bore at all - right?
Ain't nothing like that feeling of pushing your PRB or conical down the bore and watching your indicator line on you ramrod disappear past the muzzle. One of those "Awww Crap" moments. |
The rifle is rated to 110 grains of powder, so I was still in the limit of the rifle at 105 grains. But what surprised me is, normally I shoot 90 grains (according to my notes) and never pushed the rifle harder. Now 15 grains is not that much more, but it seems this rifle is a powder pig. That would have had that roundball really screaming down range.
90 grains shows 1950 fps and 1478 ft lbs of energy. 100 grains shows 2052 fps and 1637 ft lbs of energy. 110 grains (max load) shows 2135 fps and 1772 ft lbs of energy. Also Semisane.... I checked the see through powder measures I have. You are right. And they do throw light charges. I never knew that. The old brass pull out powder measures were so common for so long that I never questioned them. |

Careful there Dave, you are starting to get my mentality on the powder volumes, more is better:biggrin: Just as a side note... This is volume measure that I use and over time it has proved top be the most consistent and very close to weight....  But, Dave it only goes to 120 grains:) |

Black Powder measures volume to weight most times. But I was using a volume powder measure to make my loads.
Sabotloader I have one of them also. And three see through, and two pull out brass measures. Plus there are measure in each of the possible bags I keep. I just hate to look for them... |
Are you saying the TC U-View's are not putting out a true 110gr by volume when set at 110gr by volume?
|
i have one measure that throws a 100gr volume charge that should WEIGHT 71 grains. It however throws 69 grains. Another measure that throws 74.8 grains.
I actually just prefer to weigh my charges now. |
Check out the link below SJAdventures. It will either clear it up or confuse you more. :s3:
As a general rule, just remember that the theory behind volumemetric powder measures is that they are based on real black powder (probably FF grade) so that volume and weight are equal. So a 100 grain volume measure of FF black powder should weigh pretty close to 100 grains. http://www.huntingnet.com/forum/blac...han-yours.html |

Cept for.... 100 grains of T7-2f, BH-209 and/or Swiss BP... they measure by volume to equal most BP's and BP subs but are able create approximately 15% more power than a 100 grain load of normal BP's and BP subs. |
I have always used 3F to check powder measures with, an old timer told me that at Friendship Indiana in 1972 and I guess I have never questioned it. My U-View checks out close with it to.

So iffun my gun shoots good at the 110gr mark just filler to the 110gr mark and stop worrying about it:happy0001:
