Hi everyone, received a Sharon Hawkins in 45 cal for my B-day a few weeks ago. Now having acquired shooting supplies (powder,ball,patches,caps,etc) I am concerned about safety of using a near 60 year old used rifle. Going by online loading data powder range for 137 grain patched ball is from 60gr to 90gr. My thoughts are to sandbag the manure out of it and touch it off using 500ft of double line 100lb kite strings loaded with the full 90gr of FFF. Reasoning is I may never run full charge so if it handles it all remaining loads should be safe. And IF it fails I would rather be 500ft away than up close and in person.
Thoughts??
I dug out my Lymans Black Powder Manual and here's some interesting info.
Using a 28" bbl and 140grs fffg of Goex a patched ball has 2167 fps and 1322 ft/lbs energy at the muzzle.
At 100 yards it drops to 1153 and 378, respectively.
At 300 yards it has 578 fps and 95 ft/lbs energy, and drops 130 INCHES, right at 11 FEET.
Powerwise is about what the old 32 s&w short pistol cartridge has at the muzzle.
I'd never try to take an animal with that round at that range.
The 45 maxi ball at 230grs has a max velocity of 1831fps using 150grs of C&H fffg, and 1831 ft/lbs energy. It has 1127 and 680 respectively at 100 yards.
At 300 yards the maxi has 690 fps and 243 ft/lbs energy and drops the exact same distance, 129.35 INCHES. Very similar to the old 44 Russian powerwise at the muzzle. Still a very mild load by today's standards at that distance.
I know of no iron read sight that will give you 40 MOA of adjustment. You'd need to install a venier tang peep, and still very iffy. I fear a wounded animal would be the result.
I wanted to add some hard data to the conversation, and a little personal opinion. I hope this helps.
