Well I had a few minutes spare so took the 12 down the garden to a piece of ply that I will be cutting off to put on top on my rifle rest (so I didn’t want to put holes through all of it).
Gun - the Hatsan Escort MPA with 24" barrel
Choke - screw in cylinder (I use the gun with slugs to)
Cartridges - home loaded 34gram, 9pellet, plastic non-cupped wad, clear overshot disk, roll crimp closed, 8.6mm shot ('00') .
I'd say the old adage of, " 1 inch of spread for every yard", is pretty accurate... give or take for the odd exception.
Black circle in each pattern is just roughly where I aimed. Shots taken at 5y, 10y, 20y, and just over 30y as that is the length of the lower garden where I shoot. The 'Max' figure is the furthest spacing that I could find center to center of each hole.
Ignore the crossed out hole as that was already drilled in the sheet.
I agree. You hear of some negative stories about the Escorts and some great ones. Mines only a week or two old now but I've put well over 100 of various cartridges through it without a single let down, well pleased.
Looks like a 15" wide guy at 30 yards woulda been hit four times, and if you were 8-inches left or right, ahead or behind, you still woulda hit him four or five times. Energy-wise those are lethal impacts in that guage at that range.
Good observations, to help with that I tried to get pics of the tape measure across the sheet but it didn’t work out to great. But yeah, I'd say your pretty well spot on there.
Regarding energy, I am curious on getting some actual figures, but need to find a way of safeguarding the F1 chrony while sending shot over it at range. I’ll probably sort something so keep an eye out. Like you say its going to be sufficient though.
It does, I guess they come from similar part of the globe.
Minimum energy required to kill is considered 500 Joules. 30% of energy is retained in #0 Buckshot at 35 Meters -- you'd need at least four hits to kill. At 30 yards with four #00 Buckshot hits you're inside that envelope of effectiveness.
So not only do you have to aim your shotgun but you can see there IS an optimal and maximum range envelope and you're starting to push the first at 30 yards with standard buckshot ammo. Pellet, pattern size, and density, managed by selection of ammo and choke can be important especially as distances increase.
Not only should the plated shot pattern a little better, it should penetrate a touch deeper as well. What kind of powder are you using?
If you reduce your charge by 10% and add buffer to your payload it will tighten a little more
Ah yes I knew I had forgot one of the other major points about it. I remember tnoutdoors9 on youtube doing some ballistic tests and the copper plated pellets in one of the loads penetrated the ballistics gel much further than the plain lead shot he used in another test. Not exactly scientific as they were two different loads but still tells you something to look at. They are properly plated to, not copper-washed like many .22LR bullets.
Thanks I will look into that. Only trouble with this slow burning powder (Nobel Sport, Vectan A0) is that it likes pressure and gets dirty when downloaded but I could try other powders to. Its all European data/components. Fiocchi T5 70mm cases, 616 primed, Gualandi 18mm plastic wad.
