Don't you think you're getting a little TOO excited over a .50cal CONICAL? SERIOUSLY? It's a conical remember....call it an improved POWERBELT. It's STILL .50cal and 350grs and needs a LOT of velocity to over come those factors...
I've been thinking about this for a while...actually since this bullet first came out...my response to Hornady is WHY? Is a SLIGHTLY improved Powerbelt something I was REALLY looking forward to? Has this type projectile been on my wish list since I started muzzleloading? The short answer of course is NO! ....and here's why...
A .50cal conical is going to need to weigh a LOT to have a decent ballistic coefficient hence the FBPs 350gr weight. Hornady says the bc is .285...that's probably in the ballpark too. Well if .285 is in the ballpark for the FPB then .250 is what Hornady says the 300gr SST is and they also say the 250gr SST is .210. Boy...from HERE it looks as if the FPB is eating Hornadys other bullets LUNCH! No so my friend!
How fast do you think you can push a freaking 350gr .50cal conical anyway with blackpowder subs? Answer: Not fast ENOUGH!
Using 120gr BH209 I can push a 250gr SST ABOUT 2150fps from a long barrel Triumph....ACTUAL velocity Athens, AL if I shoot with the wind. Not allowing the bullet to rise more than 3 inches above the line of sight I an ZEROED at 170yds and 3.34 inches low at 200yds. Now THAT'S a flat shooting load and is 100% non-fiction and is DOable! Of course energy is PLENTY at that range and beyond.... Now take the heavier 300gr SST... again shooting with the wind 120gr BH209 I could MAYBE get 2000fps with the 300gr bullet. Although the 300gr bullet has a better bc, it's not enough to compensate for being 17% heavier so my ZEROED range is now 162yds and now I'm 4.52 inches low and 200yds. By now you should see where I'm going...
To have a trajectory JUST EQUAL to the above 300gr SST...the 350gr FPB is going to have to have a muzzle velocity of 1950fps which is quite frankly, NOT doable....not in Athens, AL or with the wind! :lol: It is going to be hard to if not impossible to break 1900fps using 120gr BH209... IF ONE DID get the 1950fps recoil will be 24% greater and it STILL won't have the trajectory the 250gr SST has...
I can't see myself EVER shooting anything other than a target with a 350gr FPB...sorry... MAYBE, just MAYBE I could use it as a woods gun with 100gr BH209, trajectory be damned. 75yd shot would be a LONG one! Maybe, just MAYBE it would be useful in a muzzleloader with a loose bore... On second thought, pass me the 250gr sabots please!
