445 SuperMag Multi Purpose Loads...

Anyone who's ever dealt with this fine cartridge quickly learns there is limited data for it. Very limited...

After receiving the Reeder 445 SuperMag, I decided to explore this a bit. Results were gratifying to say the least.

Most of the time full power loads are not needed. With published data limited to H11p/296, 4227, 680 and 1680, I felt more needed to be done.

Case capacity of the 445 SuperMag is .5-1 grain more than the 454 Casull. I'm certainly not suggesting data is interchangeable or that anyone should assume it is. But, at least I had a reference.

In the end, I could vary my loads for the power levels needed without firing shorter cartridges such as the 44 Magnum in my gun.

Unique provided 1200 fps with 240-250 grn cast to mimic the heavy 44 Special loads that have been and remain infinitely useful.

HS-6 and Longshot upped the ante to 1400 fps with the same bullet weights. Accuracy was superb and ballistics were consistent. This matches 44 Magnum power with less noise and fuss.

Haven't tried it, but others report Trail Boss duplicates original 44 Special and 44-40 ballistics when loaded in the 1.6" case.

I won't speculate on top end loads. My gun is built on the mid length DMAX Frame. Basically a BFR Sized Frame with a 2.25" COAL cylinder. Gary's 5 Shot cylinder is extremely strong and that's where I'll stop.

So, with the right loads, this gun can duplicate loads ranging from early Colt 44 Special to modern 454 Casull power and shoot them all into Quarter size groups.

Can figure how anybody could ask for more.

I know this is of limited interest, but thought I'd post it...
