.300 Blackout: Hornady 125gr HP and H110. Searching for Accuracy, Part 1

hey everybody welcome back to the channel on our last 300 blackout video we did not get any groups that were worth writing home about except for the groups we shot with the sig factory ammo since our gun shot so well with that ammo i know that we can get something better with hand loads we've just got to find the right combination i thought about putting together a long video loading up a bunch of ammo going to the range and shooting a ton of different combinations i think what i'm going to do instead is change just one variable at a time and see if we can narrow down exactly what the problem was my best guess is that it is the bullet and it's just a bullet that our gun doesn't like so we're going to switch the bullet today and keep everything else the same we're going with our hand formed lake city brass h110 cci 400 small rifle primers and our bullet is going to be the 125 grain hornady hollow point this is a flat base bullet and it is one that the hornady load manual has data specifically for we're going to shoot this at an overall length of 2.1 inches we're going to going straight off of their data with this our charges of h110 are going to be just about what we did in the last video i only have 14 pieces of this hand formed brass left before i have to go resize and re-prep it all so we're just going to shoot three charge weights today shoot a really quick video of 17 and a half 18 and 18 and a half grains of powder these showed no signs of pressure whatsoever with our last bullet so we're gonna see how that does today the other thing i suppose that you could call a variable that we're going to switch today is the distance is going to be just 50 yards i'm going to take this gun out to my pistol shooting area and we can get 50 yards out there so we're going to shoot that today instead of stretching it out to a hundred i think that's about it i've already showed you guys loading 300 blackout with most of these components except for the bullet so i'm just going to go ahead and get this ammo loaded up if i have any issues along the way i'll come back and show it to you then otherwise we're just going to get straight out to the range all right we are out here on my very buggy pistol range and we're shooting some 300 blackout remember this first group will be with [Music] for only four shots because we were short one piece of brass target is at 50 yards i've got kind of a weird setup here and i think this is in frame i seem to have misplaced my rear bag i think the last time i was shooting i left it at the range so i've got a bag of rice a sock full of rice and a car wash sponge kind of set in here as a makeshift rear bag but uh nevertheless we're gonna get shooting here as soon as i can get my earplugs in pardon the noise you'll hear in the background there is some harvesting going on in the field directly across from my house i'm not sure where the point of impact is going to be at 50 yards since we're sighted in at 100 yards but we're going to go for it anyway chronograph data is kind of spotty getting out here because there are all kinds of shadows i've got it in a place where i hope we can get some usable data but we'll see let's get shooting here hey right where we want it to be and we got velocity data that's what we're looking for all right i see that piece of brass you can see all the dust billowing up from in here i recently drove down some gravel roads which i don't really have in my area and this whole thing got full okay primer's nice and round no marks on the brass besides the deflector ding we're always getting but that's all right having this muzzle break on here throws dust around absolutely crazy well let's finish out the rest of this group well we've got like three and a half moa there at 50 yards that is not promising but we'll move on to the next charge right well that's a whole lot more promising i did come down to moa so that we could see our last group a little more clearly i'm going to give the barrel you know what the barrel is not even that warm but we'll give it just a second to cool down anyway and we'll uh shoot the last group last group for today we'll go on that top right hand target that last set had just a little bit of an ejector circle on so we are going to look at this next piece of brass so remember it is a half grain jump i was able to reach it and it looks perfectly fine so we're going to finish out the group well that one i have no idea why it went high it was really trying to group there i mean it was a 2moa group that's an inch at 50 yards but still man i don't know what happened to that last shot there's no way it should have gone that high all right well let's get back to the bench and we'll look at these a little closer let's have a look at this target and i think we can all agree it is a heck of a lot better than our last 300 block out outing so that first group uh was huge 1.7 inches and an extreme spread of 112. no good there but then this next group shot four out of the five shots all into the same hole uh ragged hole point three inches centered center on that which is real good then threw this one outside i'm not sure if i pulled that one or not i'm thinking i didn't pull it that far 1.3 inches still something like 2.6 2 and 3 4 moa something like that standard deviation of 20 which is not good either last group with 18.5 grains we put four shots into point nine inches about two moa which is just fine and then threw one shot to 2.2 inches which is absolutely huge again a couple of things i am pulling away from this shooting first of all the gun likes this bullet clearly a heck of a lot more than the spear tnt at least with this powder and the powder is the other thing i'm getting from this h110 for us has thrown crazy standard deviations and extreme spreads let me take a look back at the load book at our last group and this is written in pencil so you probably can't see it as much 17 and a half grains gave us an extreme spread of 36 and a standard deviation of 13 and we had a similar on 17 grains then once we get up here they just open back up wide 440 first standard deviation at 18 then we've got 15 and 36 so pretty pretty huge spreads now this isn't an extruded powder so i don't really know whether i should be hoping for really good extreme spreads and standard deviations or not but i kind of am right now i'm hoping for something better if we can get down around 10 for a standard deviation i'm going to call that acceptable so i'm thinking on the next test we ditch h110 for now and go to cfe black and we're going to try both bullets we've shot so far with it i'm thinking we'll do three groups of each and just see if we get anything that we can even base a better load work up off of so that's gonna come in the next video thank you guys for watching today if you like this video please subscribe to the channel check us out on instagram and patreon and support us over there and you all
