I've decided to focus on using a new HP for deer hunting this fall. Recently I've taken 3 different animals with 3 different guns but all 3 were 5 1/2" barreled guns so I've decided to use one of my favorite 4 5/8's old models with this new bullet & see how things work out. The bullet I'm going to use is a 45 caliber 217 gr Maxine Mouth HP breaking out of the chutes of my 3 screw shorty 45. Today was the initial work up day & I started by using 10 grains of Longshot.
Shooting from the sitting position with my back against my truck & knees drawn up (my usual position) I shot the first 3 rounds & checked with the glasses. The group was vertical but all 3 were almost touching. I decided not to make a sight adjustment & loaded & fired the next 3 of the same load. These 3 did the same thing, just made the group string vertical with all 6 shots almost touching but a tick low of my aiming point.
Next up was 11 grs of Longshot & I did make a sight adjustment before shooting the first 3 shots. These were much more centered with one shot going slightly out. I loaded the next 3 & fired using the same hold & was pretty pleased with this load. Didn't use the Chronograph, that will come later. First photo is the 217 gr. Maxine Mouths that are a clone of the Lyman #452190 except for the HP. Second photo is my OM shorty & the 6 shot group at 20 yds sitting.
I'll run a few more groups & see what kind of speed I'm getting, perhaps somewhere around 1000 fps is my guess with this short barrel.
