I just bought a TC Encore barrel in 454 casual. The barrel is 20" long. I can find lots of ballistics on the round when fired from a 7.5 or 10" barrel but nothing from a 20" Barrel.

How can I find out my FPS and energy at 50, 100, 150 yards. Also, if I zero in a 100 yds, how high or low will I be at 50 or 150 yards.
I have seen some of the ballistic calculaters but I am on a mac and they work on pc's.
I am shooting Winchester 260 gr Ballistic silvertips.

Any help would be appreciated.

Without a chrono anything would be a guess.

Search Google for the online ballistic calculators.

Bill, you can look into a PC emulator for the Mac which would let you run all kinds of neat programs written for the pc.

Safe shooting.

Im pretty sure I saw in a cabelas catalog a windows based program that gives all data like that,How do you like the 454 casull?Drop-Shot

Mountainview,
I think that is going to be my best bet. I have been putting off buying a pc emulator but I think its time to get one.

Drop Shot,
I love it. So far I have only shot it at a 25 yard indoor range.
I think this is going to be a very accurate setup. I know it was only at 25 yards but I put 4 shots through one jagged hole. I cant wait to get outside and shoot it at 100 yards.
I was surprised at how light the recoil was. Of course light is a relative term. I was expecting it to thump me pretty good. The barrel measures 1" the full length and is pretty heavy. The recoil was a lot less than my 30-06.

Thanks

Bill I recently developed wrist problems after shooting a 500 S&W,I don't know if I strained it or it's arthritus brought on by the 500 S&W.Thats just too much,I like the 454 and would like to shoot the 475 linebaugh.I have shot the 480 and it's not that bad.There is a place here that you can rent and shoot any gun they have,but they did not have the 475 linbaugh (I was told you can shoot the 480 in the 475 but not vise-versa) but of the big guns above the 44 mag,I like the 454,I shot the raging bull Taurus.Enjoy.Drop-Shot

You do know that a 7-30W or 30-30 will have even less recoil and reach farther?

My wrists can't take long sessions of thunderboomers anymore. I stop with 44mag and prefer to stay with the 7-30.

hey bill,

my sierra reloding manual tells me that you can gain 30 to50 fps more per inch of barrel length. and the type of powder makes a difference.
