I received the following interesting posts from new member Mike in Oklahoma, and decided to copy the discussion here for general consumption and comment.
I grew up in nature in the western half of the US. Joined the US Army Guard. They helped me complete a degree in Math with a secondary in physics. I was able to study ballistics theory with some great artillery minds. When it came to all the forces at play with a travel time measuring minutes, the rotation of the Earth became a factor! I was deployed to the cradle of civilization a couple of times to hand out lead pills. I am now retired from that and reside in north western Oklahoma with my family. I regularly shoot and hunt with my children. We use everything from a 10m Olympic pellet rifle to a 12 gauge rifle shotgun with enough energy to legally hunt elephants. It is quite refreshing to witness a group based in reality and applied result! Thank you for the kind invitation!
My experimental 12 gauge subsonic slug at 35m. The extra holes on the front were from #4 lead shot.
It is actually loose steel shot in an uncut shot cup with an aerodynamic cap adhered over the top. It flies to target as a slug, then looses it’s load of shot in an impressive fashion. I have used it for wild turkey hunting. Makes a head or neck shot an all or nothing proposition. The scatter pattern was made by the same ‘rifle’ with a conventional wad behind some #4 Lead as a comparison. Aim small, miss small
Fiber optic front sight and a ghost ring peep on an ultralight 12 gauge rifle of about 2Kg in heft. I usually sling it with a surplus West German G3 leather sling from the last century. It is enough for most anything around my area out to 130 Meters. With subsonic loads the barrel rings like a tuning fork after the popgun sound of the gas seal leaving the barrel.
Very interesting, Mike. From some shotgun effects on home intrusion felons I know (of) the effects of shotgun pellets. When held together there is no difference between the shot sizes - except that even bird shot is better than SG / SSG that are not contained. Without some device to hold the shot together experience has shown that a shotgun is a poor choice for home defense.
That rifle merits some closer photos, I think.
Hunting the smaller antelope (deer size) with your load may be not too popular with local hunters due to the wound size, but due to the likely lack of bloodshot meat the loss may be very little.
In the part of the country where I live shots on kudu, wildebeest, impala are between 70 to 130 meter.
Please look at the photo below of shot placement on a kudu bull: your opinion on penetration by your projectiles of the on-side shoulder, the rib cage and then demolishing the heart will be interesting.
The heart when viewed from flat side-on is protected by the humerus bones and then rib cage. In this typical stance the heart top chambers (which is what we aim for) is directly behind the humerus-scapula joint (the shoulder proper). That is quite a solid structure for a bullet to break through, then break through the ribs and then cut open the top chambers. With a rifle the preferred combination will be a very well constructed bullet like the Peregrine VRG-3 expanding monolithic copper, a Barnes TSX, a Federal Fusion and maybe even a Hornady Interlock in the following chamberings and weights: 30-06: 200 gr @ 2,600 ft/sec. .308W: 180 gr @ 2,600 ft/sec. .303 Brit 180 @ 2,550 ft/sec. 8x57 Mauser: 225 gr @ 2,600 ft/sec. 7x57 Mauser: 173 gr @ 2,500 ft/sec. 6.5x57/58 Mauser: 160 gr 2,500 ft/sec.
Look at this impala ram which is an 80kg animal, compared to kudu that are elk size.
Much the same presentation, except that the resistance to the "bullet" will be less. Local hunters still use the same bullets as above even for much smaller game.
The composite slug I discussed previously was for a very specific time where two seasons overlap. Or where I may shoot coyote. I really enjoy the stalk of alert species such as turkeys out here in the west. Getting powder burn close is thrilling. My usual projectile for deer and such is a Lyman sabot slug of 17.5mm in diameter. It has been cast out of exceedingly hard lead, approaching the hardness of copper. At higher velocities in my other 12 rifle it passes through steel and iron with vigor. The pure lead variety weighs 34 grams, yet the hard ones I have weight in at 33 grams due to the alloy.
I have pushed them beyond 2200fps in an 8 Kilo rifled 12 gauge. I have nothing worthy of that down range energy here, but it sure wakes up the 200m gong at the range! If I get drawn for an American Bison cull I may load that one up for an exciting adventure. I do have a wonderful Kar98 with receiver peep sight in 8x57 I enjoy shooting, it was my grandfather’s rifle and I enjoy the family history of it. I will send more pictures of my ult light 12 rifle in short order.
