Chronograph Data Wanted

[JamesT]

Have any of you personally collected any data on different calibers and charges using a chronograph. I don't own one but would like to see some info on this.
What really got me thinking was a rifle I shoot fires a .429 ball ahead of 60gr. FFF. Wondering if it has the velocity required to humanely take a whitetail deer. Besides proper shot placement what would be needed to be lethal?
Would also like to see data for smaller calibers and up to a .530 ball ahead of 80gr. FF.
If any of you have put the time into actually collecting this data id love to hear about it.
Regards,
James

60 grains of 3F in any caliber between 45 and 54 will cleanly kill a deer.

I shoot 55 grain in my 45 caliber deer rifle with hollow based min's or round ball and it is lethal over 100 yards with the mini's and 75 yards with round ball. Now days with my old eyes and bad back I don't shoot over 75 yards so I use mostly round ball.

Go to CTMuzzleloaders.com and scroll down to the free ballistics calculator. It will give you a real good idea of velocities you might obtain with round balls from various barrel lengths.

I ran a couple of loads from my 45 Seneca with a Speer RB and MV agreed closely with my TC load book. I carry this gun in the NY muzzleloader season loaded with 60 gr FFFG and 195 gr Powerbelt bullet. Haven't taken a deer with it, but it I treat it like it's a 45 Colt handgun and would keep the max range around 80 yds.

Over on the sister site there are a few folks who posted data, mostly factory data, but it might be of help as a comparable for a starting point

That is interesting. The 10 gr. powder difference really picks up the velocity. That is a heavy bullet too. I am curious what a round ball would look like.

JamesT, my chrono data was with a RB. I haven't chrono'd the Powerbelt.

Pic a bit blurry, sorry

Oh great. I only shoot round ball so thats perfect. The pic is a bit blurry but I can make it out just fine.

This may not mean much but I killed a deer at 75 yards with a round ball and 60 grains of 3F....one shot.

Understand, now, several factors can have a major effect on powder vs velocity. A .40 I owned gained 200 fps using 60 grains of 3F simply by going from pillow ticking patches (.015") to mattress ticking (.018"). Velocity isn't necessarily linear, either. That same rifle was averaging around a 60 fps gain with every 5 grain increase. But at one point when I upped the charge by 5 grns the chronographed velocity jumped nearly 250 fps. Round ball is the only projectile I've ever fired in a muzzleloader and the figures posted were, of course, fired with prb.

I have shot a few deer with 52 grains by volume of 3F and a .530 roundball @ 50 yards none have taken a steep
