6/21/2023 0 Comments Subsonic 7.62x39 loadsHornady 50 round sst packs of loaded ammo pretty darn good for supersonic stuff I seat till lube groove is inside case and they feed fine through mineįind another mag and get it shortened to 3 shot as rifle is so much nicer to carry. 22lr and today when tried it again reinforced why I changed to the x39mm in first place. I doctor projectiles just a little and can get 14mm wide mushroom on the only projectile recovered from 20 odd Ive head shot my house muttons with.piss poor preformance put me off. When I get some more Im going to load them above subsonic and be happy with a quieter than full power load that has more ooomph than true subsonic Start at 8grns of trail boss with a std primer and work your way down to 6ish till you get sound signiture telling its subsonic or use chrony till 1000fps reached Sure some might be thinking i am wasting time and money on this silly cheap chinese rifle (and your right) but the way i am looking at it is why have a cheap chinese rifle that shoots like a dog and never gets pulled from the cabinet, id rather do all my learning with a rifle that i dont care to much for.Ĭontact shootersnz/robert or just buy some of his AWESOME projectiles off trademe I am hoping someone here has been down this track before and tested many different powders, projectiles ect and may have a good recipe to start with, Also if anyone would like to throw in some first timer tips that would also be very helpful, I just ordered my first press and plan to start my learning with this post, I have a crappy old 7.62x39 bolt action Norinco that i have decided to do my learning with, I have shortend it by about 150mm, and sent the barrel away to get threaded, it now has an over barrel suppressor and shoots horribly inaccurate lol, I have also removed the old shitty stock and carved my own stock from some kind of native wood plank i found in the roof of my shed (actually came out really good) I want to have a play around loading up a few types of sub sonic loads, and hopefully get a bit more accuracy from it at the same time, i plan to do all my test with a chronograph. 6.Hi all, this is my first post, i hope to use these forums more.6.5 Grendel Target & Competition Shooting.6.5 Grendel Bolt Actions & Single Shots.Firearms Industry News and New Products.Quick Navigation 6.5 Grendel Ammunition & Reloading Top You don't want to get a bullet stuck, trust me. Accuracy is secondary because these loads are effective only at short distances.Īlso remember to work down, not up, on subsonics. That's what you need to look for more than anything else IMO. Since you are not needing to cycle gas system you can just play with them to see what gives you the lowest extreme spreads. Keep in mind all of my data is for 160 grain bullets so adjust accordingly. PM me your email address and I will send you a PDF with the data. Of the powders you listed I tried Trailboss (DO NOT recommend for Grendel SS), 8208, Unique & Xterminator. It also increases load density (good for consistency) and reduces the chances of secondary explosive effect (not good). You loose a lot of energy by reducing the speed but you can gain some of it back by adding weight. Those bullets you listed probably will stabilize but I always recommend going with the heaviest bullet available for subsonics. I had the lowest extreme spreads from Remington 9 1/2 primers. Your project will be very easy compared to a semi.ħ.62 brass is a good choice for reduced case volume.
