.308 subsonic ammo with 170gr cast boolit

[MaxJon]

I am currently loading a subsonic load for a military rifle match (7.62 NATO) at our local pistol club for which we have 600 joule limit. Hence the subsonic velocity.
My question is: What would be the effective hunting range of the load below:
7.0 grains of AP50N (same as WST) fast burning pistol powder, behind a cast Lee 170grainer using CCI magnum primers for better ignition. Will chronograph this load soon, to get a better indication. This load is super accurate at 50yds! I think 200yds would see it out. Any advice/info would be gr8![smilie=s:[smilie=s:[smilie=s:[smilie=s:[smilie=s:[smilie=s:[smilie=s:

What do you intend to hunt?

In my experience using Red Dot in a 30-30 7 gr would start to show instability at 200 yards as the 308 case is larger velocities would be lower. In my experience WST really works about the same as Red Dot so my guess is that 100 yards would be the limit for accuracy and maybe a little further. Most of my experience hunting with low velocity 30 cal bullets is that they are perfectly adequate for most small game out to 100 yards but then hitting gets more problematical due to trajectory of the bullets. As for game of deer size and larger I would consider the load inadequate.

I shoot a similar load in my 30-06 its 6 grs of Bullseye and a 160 gr.Lee spitzer boolit it shoots very well out to 100 yds(2 moa) but at 200 I do get some vertical stringing. As for killing animals? I assume it would have the same energy as a heavy loaded 38 spl. 160/170 gr bullet @1000+- fps. at the muzzle but with a smaller dia. smaller meplat nose.

Veral at LBT has written a bit on what he calls "Quiet Bullets". Might check him out, he has a lot of experience that he's willing to share.

load a 220 or even 240 grain bullet for that hunting load and it will kill deer way out there

The trouble is he has to stay at 600 joule or less. The heavy boolit will shed it's energy at a slower rate then a lighter boolit but it will require a faster twist to stabilize.
