![]() Definitely hit again, it slumped over in a fork in the tree and wasn't moving. I heard it hit a tree branch and zing off into the field again. Distinct impact and the raccoon let out a squawl. I go for just in front of the left hind quarter, going toward the right front quarter, aiming about 1 1/2" high for sight-over-bore and send another. This put it directly in line with my neighbor's house, so I change positions to get a safe shot, get up to about 7 yards and line up another shot with the raccoon quartering away from me. The raccoon scurried a bit, then reached out to a tree branch and crawled over into the tree. Heard impact, followed by the bullet zinging off into the field. I was able to get a good angle on the raccoon, about 15 yards, broadside, using a 2圆 sticking out of a junk pile as my rest and send it. So, I go put some pants and my Crocks on, grab the Ruger and chamber one of the subsonic rounds. My dog had a raccoon on top of the well house in my front yard. So, I get up and go outside in my undies with my pistol and a flashlight. She's been doing this frequently at around the same time for weeks, I just haven't been able to get out there and find anything. I wake up to my dog barking at something, obviously very upset. Small, self sealing holes.įast forward to 0500 this morning. Kinda confirmed by guess that these things would likely just pencil right through. I went to see if I could find any blood or other evidence of the hit. ![]() Fired, heard the report of impact on the rabbit followed by the sound of the bullet striking something behind the rabbit and then zinging off into the desert. While out cruising around, I found a large jackrabbit at about 15 yards and decided to make him a test subject. I'm unsure of exactly what bullet they are using in those loads. I was pretty sure the hollow point bullets would not expand at that velocity. So these are looking to be probably 75 yards and closer rounds.Īfter having that info, I wanted to see how they would perform on a varmint. They were pretty well right on at 25 yards, a few inches low at 50 yards and around a foot low and showing signs of tumbling at 100 yards with about a 4-5" group. I took it out to see where they hit with my current zero to get an idea of what I can expect. I have the rifle zeroed at 100 yards with a different load and didn't want to change it for the subsonic loads. Something that would be much more quiet than a standard 223 load so as to draw less attention from neighbors. Second, I wanted a varmint round to use around my place for coyotes, skunks, raccoons, squirrels and other feral animals. My purpose was, first curiosity and wanting to play with them. I have not chronographed them out of my gun, but they are subsonic. They are a 77gr BTHP bullet at an advertised 1050 FPS. I ordered a box of Atomic subsonic ammo from Midway. Some time back I decided to try some subsonic 223 ammo out of my "quiet" Ruger Ranch bolt action. Having a high BC bullet at subsonic does not benefit the shooter at all.This is kinda a confirmation of what I had already expected and a little info for others. BC (ballistic coefficient) is for supersonic flight, and does not matter at subsonic speeds. This allows the 75 grain HP flat base to be more stable and have the potential to be more accurate at subsonic speeds than a BTHP design that makes the bullet longer, requiring more twist rate to stabilize it. The 75 grain Sierra HP flat base is a much shorter bullet than a similar weight BTHP bullet, or a 100+ grain SP or HP bullet. In a given 243 Win twist rate (like a 1:10″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer BTHP match bullet is. Bullet length is a major factor in how stable a bullet is in a certain twist rate. 243″ bullet to fully stabilize at subsonic speeds in a given twist rate, bullet stability becomes a huge factor for it to stabilize and shoot well. Why use a 75 grain HP bullet? Most 243 Win barrels will have a 1:10″ twist barrel, with some having a 1:9″ twist or faster. ![]() This is with new Winchester nickel brass and Barnes 72 grain HP bullet. New!! By request, I recently developed a 243 Winchester SUBSONIC round shooting the 72 grain Barnes HP at 1030 fps in 22″ barrel. ![]()
