Pretty darn vicious when fired from a four inch barrel, no?

The 125gr. Buffalo Bore load couldnt have framented too badly as it went 16 inches deep and only lost 7 grs. of wieght. This bullet is the Gold Dot LV. (low velocity)

Thanks JE223.

That ain't bad for a .38. The Buffalo Bore is bordering or .357 performance, with less recoil and muzzle blast. How do they do it? "Secret's in the sauce."

Among other issues, the fact that the Gold Dot is holding together when this severely "overdriven" is pretty cool. Like Tim says, 7 grains loss ain't a big deal when you consider what's being asked of the slug.

The Federal in comparison to both looks to be junk. Sure, it'll "work", but there's no standard for +P+ pressure so unless your gun is really a 357 that's got to be a concern. It's losing mass like crazy, if it hits a barrier first God only knows what'll happen and it has nowhere near the energy of either Buffbore load...and the 158 is kicking it's butt in that department and sending it running home to mama.

The BB's are pushing some nice velocities. They are leaving the +P+ in the dust. I like what I see. Knocking on .357 velocities, 9mm easily. Once agiain, great work JE.

I'm sensing an affiliation between Buffalo Bore and 351? :rolleyes:

Not that it really matters because everyone likes to see gel test results!

I'm wondering if using the four layers of denim as sort of standarized by DiFabio at Ammo Lab (back when) would effect the results?

The Gold Dots are an excellent choice and likely wouldn't be "plugged" by the denim....SWAG?

Including DT brand into this equation would have been interesting IMHO.
