Can you mix powder

I have been slowly filing down the front sight. It does group well at 50 or 100 it just runs out of adjustment to hit the center of the target at 100, 50 grns of 3f was doing great at 50yards but even up to 100 grns does not get me high enough to hit center at 100. I have been using a 220 grn round ball and 3f black powder. I just got some 2f triple 7 from hogdon I played with it a little on saturday but I only had about 25 yrds to shoot in. I did notice that it was a little slower to take off though.
 
Did you get my P.M.??? What model CVA are you shooting? Whats the ball size(i.e..490 or .495)? What patching material are you useing? What`s the twist on the barrel? Did you use a large cardboard target backer so you can see all shots at 100yds.? How many inchs apart were they? If your shooting patched roundball in a 1x28 twist barrel, put the file down, most likely your not shooting any kind of groups at 100yds. Get some sabots and try them. The Hornady SST`s 250grn. sabots are about $14. Your front sight will be more.

Shortwave,

I am shooting a trade rifle and I am not sure of how many twists are in the barrel, but it is a .54 and I am shooting a .530 ball and a .015 patch.
 
What kind of primer are you using? Not quite sure what you mean by 'trade rifle'. To find out your rate of twist put a cleaning jag with patch on your ramrod. Insert ramrod, mark a line on ramrod, slowly pull ramrod out paying attention to line and to how many revolutions ramrod makes. A 1x28 twist is 1 twist in 28 inchs,1x48 is 1 twist in 48 inchs etc.
 
"trade rifle" is what it is called kinda like a Hawkins only it is a trade rifle, It has a 1x48 twist from what I could find from a quick internet search.

From what I can find on the internet it was a popular rifle for tradesmen and Indians. Basically born out of the fur trade. I was using CCI's now I am using Vorderlader-Zundhutchen. I was told they are hotter.
 
Its looking like your headed back to filing the front sight or shimming the rear. Whats the bore look like especially down at the breech? Have you tried any .535 balls with .010 lubed patchs? How tight is the .530 with lubed .015 patch? Just want to rule out to much blow by.
 
If I don't run a patch through after every shot it is very tight running the ball down. Other wise it is fairly easy to run down, it is snug but some what easy.
 
If it's only 1 foot low then I would just use Kentucky windage and aim high when shooting at 100 yards, but that's just me.
The last time I adjusted rifle sights to shoot at 100 yards it greatly affected the point of impact at 50 yards which is the distance that I do most of my shooting.
So sight adjustment is often simply one of those choices of personal preference that the shooter decides to make that's mostly based on the distance that one plans to shoot from the most.
A 50 yard target is basically just a 100 yard target that's reduced in size, and many rifles will shoot more accurately and using less powder at 50 yards. And believe it or not, some folks have a preference for shooting at 25 yards with even smaller targets.
It's all good!
But where to aim at the targets for each distance is one of the main challenges. :)

+1 on what Articap said. If your going to hunt with this rifle and most your shots are 40-75 yds., I wouldn`t zero at 100. I`d zero at 50 and shoot enough to know where I had to aim at a deer at 100. You keep filing on that front sight and you may not be able to zero at 50:eek:. Then you gotta add that bead of weld on the front sight. Thats the only problem with filing front sight verse`s shimming rear sight. By the way, 2-3" groups at 100yds. with open sights ain`t bad;).
 
According to previous post`s I thought you were zero`ed and grouping good at 50yds:confused:. My advice would be the same as Arctic`s, zero at 50 and hold over for 100.
