Thread: Reloading 6.5 Grendel Subsonic ?

Thanks Cordite, I have read about some dangers of subs and now I understand ! I plan on getting some ADI 8208 on a recommendation for standard loads, just been thinking everytime were in the bush there's always other pests to shoot, especially lots of possums. I take your point on the 7.62 x 39 and we are thinking probably cant go wrong with either, just think the 6.5G is probably better suited for the general hunting we want to do. Great idea with the #2 buckshot and we may try that if we cant find a bullet that will do the trick.

Do NOT use a slow powder, danger of detonation rather than conflagration... detonation meaning that a small charge can turn the chamber into a fragmentation grenade. Slow powders CAN be used for subsonics, but with wadding keeping the powder up against the primer hole, but really why bother/risk it when Trail Boss is not that expensive.

Agree it's easier to just use full power ammo for accuracy, but out on DOC land you have the no-rimfire restriction... and full power centrefire ammo is a really shitty idea if you want to shoot things out of trees. For subsonic loads, play with cat's sneeze loads just using lead ball. US #2 buckshot is 6.9mm and can be pressed into a 6.5 case (actual bullet diameter 6.7mm) with a smidge of grease on top. Look up the Trail Boss loads yourself. You won't need a silencer.

But ... while you are thinking over your purchase...why not choose the Howa Mini in 7.62x39 - significantly better for subsonic loads, and much cheap ammo available to the boy.
