'92 clones are the strongest, Marlins pretty close, not sure about the Henry.

In my .45 Colt Marlin 94 Cowboy, I shoot 300 gr. JHP and cast bullets ahead of a full charge of H4227. That powder has a smooth pressure curve and great performance in the .45 Colt. For that reason, one may want to check out H4227 loads in whatever rifle or pistol in that caliber.

Well it's a brand new octagon barreled Henry without any obvious model engraved, I'll go through my paperwork and get back to you guys.

Your loads of 250 grs at 1000 fps will be fine, I shoot 270 gr Thunderhead bullets in my 45 Colt SAA revolver at 940 fps, and have been for years without a problem to the revolver.

Henry also makes a 44 Magnum lever action rifle, and I am most certain those loads are much higher pressure than the load you mentioned, I'd get that rifle zeroed with the above mentioned load and be practicing for deer this coming fall 2013.

Those 270 gr. Thunderheads by Penn Bullets are bad medicine for hogs. The huge meplat packs a wallop.

I have a line bored three screw Ruger Blackhawk, turned into a .45 Colt from the original .44 Rem Mag. It has a 6" Shilen barrel, long steel ejector housing, custom front sight, work done by Jim Stroh at Alpha Precision. I rigged a trigger stop and did a trigger job. I shoot the Thunderheads with a full house load of H4227. Accurate and deadly.

Havent got to try 'em on game yet DF, but the KA-WHOP!!!!! I hear when the bullet meets a damp pond bank or the test media indicates sho nuff pain and discomfort for the recipient.

I cant wait to find out first hand.

Here are the 270 gr. Penn Bullets Thunderheads and the custom Ruger .45 Colt, now wearing stag grips.

There's that little sledgehammer of a bullet , and nice pistola too DF.

Given my proclivity to shoot your ammo, Gunner, I may just bring my 5.5" SBH and "forget" my LC ammo!

That is one bad-azz looking hog-killer!

I would call the manufacturer and ask what the recommend.

Bring it George, I got a couple hunnert of the 270 gr Thunderheads loaded up, with 10.0 grs of Power Pistol they run a mild 945 fps from my old Colt SAA, and are very accurate and shoot to the sights to boot, they would make ya a fine Boar Killen' load.
