    Yep, as suggested by @tikka on the 300 blk thread, 50m probably a sensible range to stick to. Around here that is a long shot. Expansion and terminal performance was great. Granted not the best shot I have ever made, but I have had deer go a hell of alot further with full power rounds. Thanks Robert, will use these with confidence.

    Yes they seem to shoot ok at sub velocity I wouldn't try them faster would more than likely strip, I can get them to.3105" and they are soft so will obturate up a little.

    Went down this track loading up some 220gr freight-trains, had a couple jam in the barrel trying to get load subsonic and decided it was more a theoretical exercise than really achieving much practically. Massive Attack is onto it, using say a dedicated AR with say 147 xtps would be quite handy or some of the 45 cals but harder to import bits/brass etc. The 300blk has shown promise with the Leigh bullets otherwise is a plinking cartridge subsonic

    308 trailboss minimum charge with 150gr projectiles

    I have worked down from 10gr of trail boss to 7.4gr to get to 1050fps in my 18" Bergara 308 using Roberts cast 151 hp's.
    I have read that 70% of max charge is the recommended minimum charge. 7.4gr is about 55%. Although I've not had any issues, should I be worried?

    BTW have been using these projectiles in my blackout with 3.6gr Trailboss with great results. They mushroom well and not much runs away. Single shots are great, easy to pick and choose between sub and super where and when required.

    I use 7.8 gr of trailboss behind the same projectile out of my 16 inch mod 7 308 and they are good as gold. Only taken a few smaller goats within 50 yards so far, but that is really what I loaded them for.
    Another plus, is that my mates 6 yr old can shoot the rifle with ease.

    I have got down to 5gr trailboss in 308 with no issues.....That however is a pretty marginal case fill of around 50% and not ideal.
    You will be fine at 7gr+
