I just recently came back from a South Texas hunt where I was able to harvest a Javelina with one of my muzzle-loaders.
The gun is an older FIE 'Kentucky' rifle... I've cut the .45 barrel down to about 19" and named him "Shorty". While I like to use more traditional projectiles in my side locks, the most accurate load I've found so far for this gun is the 200 gn hornady XTP, in a blue, Harvester sabot over 44 gns of FFF grade Triple Seven.
Haven't chronied the load yet, but I'm guessing 1100, 1200 fps. Seemed wise to maybe go slow with a bullet designed for handgun velocities.
I was able to get a shot on my Javelina at about 20 yards. Full-frontal shot. Once the smoke cleared, I walked up to the expired skunk-hog and found that the bullet had entered in front of the right shoulder.
I was happy to see that the bullet hadn't exited (even as I was taking the shot, I was grateful for the angle and was thinking that the bullet could be recovered if I could make the shot).
I hadn't killed anything with this gun/load and was anxious to see the damage, a quick scan with a Garrett metal detector showed that the slug was still in the pig and had traveled about 12" from the point of entry.
Here's the Javelina and my "Shorty-Forty"
Here's the front of the recovered XTP (Widest portion measured about .81)
And the back of the slug (retained weight=134 gns)
I hope I don't get in trouble for this one... no offense intended, but I was so impressed with this bullet's performance upon field-dressing... I couldn't believe it, but here is what was left of the heart...
So there you have it: Shoulder broken, heart demolished, lungs destroyed, a piece of the liver was missing aprox. 3/4 the size of a playing card... I don't think the Javelina could have been any deader if he'd swallowed a hand grenade!
I would definitely hesitate to drive this bullet much faster though, I doubt that I would have found anything but maybe the copper jacket if it had been pushing 2000 fps.
HH All!
