ballistic information wanted
I have heard that inline rifles can match and even excel a center fire. I am sure there might be loads that can do that but I have no chronograph and am ballistic illiterate in that department. What kind of load do I have to push out of a .50 caliber and what kind of center fire do I have more whoop then.?
I know a lot of you out there are into numbers so I was hoping you could help me out. Also, after this data is given, let me know how many of you match a load like that when you shoot...
thanks.

There are just too many wild claims being made these days by a lot of people who should know better, so be very careful hat you choose to believe!!

I could not agree more. It was mentioned that a modern inline rifle will equal that of some centerfires. A 45-70 Government was mentioned. Now when I was younger, I had a chance to shoot an old bolt action 45-70 Gov and I remember the recoil and the down range energy from that rifle. So when I was told that an inline could duplicate those results, I was interested in trying to learn what load and powder charge would have to be used to make such a shot.
The 45-70 normally shoots a 405 grain FP projectile in around .458 diameter. I've found three different speeds for this cartridge. They ranged from 1300 fps to almost 2000 fps. Well I do cast a 405 grain pure lead FP .457 diameter bullet and shoot them out of a red Knight sabot. I was trying to see how much powder I would have to put under that thing to make some of these velocities. I have a feeling it would be more then I normally shoot, which is 100 grains of Goex 2f.
I do thank you for your reply...

Cayugad - some of the magnum loads, using three 50 grain Pyrodex Pellets and a sabot bullet, can come very close to the horsepower ofthe stiffest .45-70 load. In my Marlin 1895, I can safely get a 300 grain Barnes X going almost 2,000 fps (actual chronographed velocity). Out of my 26" T/C Black Diamond, I can get the 300 grain Expander MZ up to 1944 with three 50 grain pellets. Pretty darn close . . . .

Well then it is true that some of the modern muzzleloaders can get to some center fire standards. Of course I am not sure I want to shoot 150 grain loads.....

cayugad,
I think you have seen this before, but one day I was out with my A&H not really trying to set any velocity records, just checking a hunting load. I was shooting .458 (45-70's) 350 grain Hornady Round Nose bullets.
I, at the time, was thrilled with the velocity across the chrono.Especially with a 350 grain round nose. I have settled back a notch to a 300 grain Nosler Partition .458 bullet as my my Elk load. It is a little more efficient and quicker.
Any way here is the target and velocities - I appologize for for using blue ink on a blue target.....

RE: ballistic information wanted
that is a real respectable load sabotloader. 1600+ fps for a 350 grain projectile. Having nothing more to base this on then a guess, I would put my 405 grains with 100 grains of Goex 2f somewhere in the mid to high 1400's since the powder charge is not as hot and the bullet is a little heavier. Again, a real respectable charge. I bet the elk do not care for them at all.
I have been shooting the homecasted 405 grains at100 yards and they have been behaving real good. The only thing I can figure the occasional flyer is from my casting. I cast them out of pure lead. A friend tends to think they are heavier then 405 because we did a homemade balance beem type test with a factory Remington 405 FP and the home cast were heavier.

Well, I don't shoot a modern inline, but I do have a sidelock. I get about 1200 FPS with my load of 80 grains of Goex 2f and a 370 grain T/C Maxi-Ball. Going off of other loads I have chronographed, 100 grains (max powder charge I can use) will only give me in the neighborhood of 1300-1320 FPS. I doubt even with a modern inline I could come close to matching the power of a modern C/F. I am sure that the ML's pack the punch of the smaller ones, as far as kinetic energy, but only for a short time. I am thinking like the .243, 257 Roberts, 6.5 X 55 and similar. Even these cartridges would probably actually surpass an inline ML after the 100 yard mark.

RE: ballistic information wanted
This is my reason for the search. It was mentioned on a different forum that modern inline centerfires can equal that of a center fire rifle. A 45-70 Government was actually used in this comparison. I felt this might be a boast but felt before I replied to this claim, that I should have information backing up my statement no matter which way the findings show..
