Windham Weaponry 450 Thumper Pistol

Postby Bwitty72 » Mon May 14, 2018 2:20 pm

Hey guys, newto the 450 and just recieved a Windham Weaponry 450 Thumper "pistol" to play with.

My question is...What kind of Ballistics do you get out of the 9.5" barrel. I wanted to use it for close quarter hog hunting, but kinda curious how far out I can reach with such a short barrel.

Thanks!

No clue. I have seen a couple with shorter barrel 450B, but only one that I know of that got some velocity readings. However, those were from an 11.5" Franklin Armory barrel, if I remember correctly. I have a feeling the 9.5" is going to be hurt pretty good in the velocity department. If you plan on pig hunting with it, I would suggest using a chronograph to figure out your effective range for each different bullet you plan to run. From there, you could test the bullets on water jugs at different yardages to see how well they perform.

Some suggestions, though. The 225 FTX is designed for the 45 Colt, so they should still be a good performer. The 250FTX might still be a good option, can't remember the minimum velocity needed for them, but they seem to still expand at 150-200yds, if I'm thinking right. The 275 might still give you decent performance because of the very low opening velocity (1200fps). The 200XPB probably won't expand past a few yards from the muzzle if I had to guess.

Or you could try FMJ and solid bullets. Even though they won't expand (the FMJ's might flatten a bit), your still going to be punching a 45 caliber hole through the animals, and penetration shouldn't be a problem. Won't be as effective as an expanding bullet, be with good shot placement, it should still be enough to kill them. You'll most likely be doing some longer tracking.

Like I said, I really have no clue. At this point, your the guinea pig, so do a lot of testing, and let us know what you find.

C'mon guys, get the chant going! Load subsonics since you're halfway there already. ;)
