issue with reloaded 7.62/39 AK ammo
I recently had a friend accompany me to the range to sight in his SKS carbine,
once we got too the range his carbine produced consistently poor accuracy,
it took awhile but we eventually found and isolated the,
the primary reasons his ammo produced 12" -15" 100 yard groups.
sort version, the carbine he owns has a .311 bore diam.
and he had use a rather slow burn h4831 powder and .308 diameter, 130 grain bullets.
he had purchased in 500 count zip loc bags at a local gun show ,
(manufacurer un-known) cheaply to use in his SKS reloads
those two factors combined just don,t work well in his SKS
https://www.speer-ammo.com/products/...le-bullet/2217
these speer 150 grain .311 diam worked far better.
over 25 grains of accurate 2015 powder

Sounds like a pretty severe case of owner ignorance, to reload ammunition for his firearm using the wrong diameter of bullets. No reloading manual ever printed has neglected this fact, so he was either ignoring reloading data, or trying to repurpose the wrong bullet diameter to save some logistical headaches - his fault either way.
Not sure why a simple anecdote necessitates a handful of pictures and links to others’ work, but I guess that’s a thing some people do...

just trying to make all the related info easy to find for the few that might be interested
, many of the people new to reloading will not have bothered to do the research ,
and will not be aware that the 7.62/39 ak 47/sks carbine,
uses a different diameter bullet than the 7.62/51 (308 win)
theres always people that don,t read the instructions and fine print.

but just the fact your pointing out two totally different calibers here?
7.62/X39
7.62X51 (308 win)
any reloading book should tell you what bullet they call for
so, someone just didn't bother to read ANYTHING before reloading here IMO
and that is the kind of thing, that can be dangerous real fast, as pressures build
reloading isn't meant for skipping info?
sorry, not bashing, we all live and learn at times, but, I would hope anyone reloading ammo, would take the time to read on what are the proper bullets, and sizes and powders being needed to produce safe reloading ammo!
I have sadly seen a few guns come apart where folks took hits, and hope to not see anymore

I can only point out what I see other people do,
I don,t condone or understand the lack of motivation,
nor lack of attention of detail.
yet I can point out stuff like this happens on a rather regular basis.
theres not a single person on the planet thats never made a mistake , doing something.
we all learn from making those mistakes as this guy did in the process.
locally theres only a few of the guys I hunt with that reload,
I tend to be the guy they ask for instructions from.
this guy is in his early 20s and just getting started, (one of the guys I hunt with sons)
so its hardly an unexpected development, in the learning curve.
and frankly theres far worse mistakes that could have been made.
yeah, being a mentor helps,
but you don,t always get to dive in before the guys make mistakes or ask questions

I agree we all make mistakes
but when dealing with something dangerous and mistakes can KILL you
a NEW reloader, should be one that looks at everything closer and twice if not 3 times before using or doing, to make sure they KNOW what there doing
trying to give excuses for why someone screwed up after the fact
honestly tends to come down to the person that made the screw up, , didn't take the time or EFFORT to learn anything, they THOUGHT They knew it all and just went and did something, only to find out afterwards they screwed up and DIDN"T know what they were doing
this attitude is IMO, sad, and getting worse with the world today
folks watch YOUTUBE vuideo's and suddenly THINK there experts or can do anything, without any other education ,m and NEVER even checking to see if the guy on youtube, even knew what he was doing they just take crap they find online and assume its FACT
I would gather its NOT just me that thinks, common sense is a fading trait in humans in this modern era of everything is ONLINE,
as well, as making a lot of tech advanced morons that don't really ever learn anything from reading ALL about, all about shortcuts these days
rather watch a video and THINK they learned something, over taking the time to properly LEARN something!
the OLD saying
"DON"T JUDGE A BOOK BY ITS COVER"
is sadly IMO< the ONLY way anyone wants to learn anything today
they see a picture of a video with a short title about"X"
watch it and assume its MUST BE TRUE if its online LOL
NOT again bashing your friend, just saying, I see a sadly slipping society of folks that don't want to spend ANY amount of time to LEARN, when they can watch short video and THINK They learned something!
everyone wants to JUST push a button these days, ZERO patience, and far too many THINK they know it all and have zero experience in things they THINK they know!
I'm again glad he didn;t get hurt or anyone around him!
