I need to know what powder, charge etc you use :D I would love to make some subsonic 30 06 cartridges.

@heintron

vihtavuori N310 powder. 10.2 grs.

Hornady 180grs RN bullet.

COL 78mm.

Subsonic loads in 30.06 is not for beginners, and your gun will blow up if you double-load.

@pederkristoffersen I see. I have actually bought some N310 for making subsonic .223 loads. Figures it should work for 30-06 as well. I will make some quickload calculations and see what I do :) Thank you!

@heintron

Nice then you'r all set!

I started at 12 grs and worked my way down to 320 m/s.

Not funny to start to low and get the bullet stuck in the barrel.

1:10 twist should get the 180grs bullet going, but heavier bullets could be a problem.

You can also try to seat the bullet upside down to minimize the shellvolume.

The lower COL the better, usualy.

hva slags effekt da? Anslagsenergi? Ekspansjon?

Kula oppfører seg som en feit helmantel. går rett gjennom uten å rive noe.

Har skutt måse mellom øynene og det ble to små sår.

Men kula går gjennom hva som helst.

[heintron]

@heintron I used 10 grains IMR Trail Boss 155gr Noslers and got velocities under 1000fps.

I cut a wad from a facial tissue (Kleenex) by placing a penny over it and cutting around the penny to hold the powder to the back of the shell. After dropping the charge I set the wad over the mouth of the shell and push it in using the blunt end of a pen or pencil, packing it down lightly over the powder, being careful not to crush the powder. It keeps the powder against the primer for a more consistent velocities. I used 10 grains IMR Trail Boss 155gr Noslers and got velocities under 1000fps.

@pederkristoffersen I have the Sierra 2160 180gr spbt bullets, 1:12 twist barrel and it is 53cm. With 10.2gr N310 I get 411ms/1350fps in quickload. I have to go down to about 7gr to go subsonic. But that only fills the casing up to ~21% which is kind of... little ;) If I bring the COL down to 78mm I at least get a fill of 23% but the speed increases... I guess I should bring my chrono out to the range and start at 12gr loads to be sure.
