    The .308 is so easy to load for.

    Never loaded for a .308 until recently. So far, I have loaded 150 gr. and 110 gr using N140 and & Benchmark respectively. Outstanding accuracy right out of the gate. I had heard the .308 was an easy one to load for, first hand experience really makes it sink in. I think it would be a perfect round for a new hand loader. Naturally, a good rifle helps.

    I am starting my reloading journey for my .308, looking at 150gr or 155gr to run it on. What is your barrel specifics? I am running a 20" heavy barrel with a 1:10 twist rate.
    What bullet make where you using?

    happy loading

    I'm shooting a 20" barrel too, a Steyr. Loading from the Nosler #7 manual. 46 gr. N 140, Hornady 150 gr. SP. And Hornady 110 gr. Vmax with 47 grs. of Benchmark. One ragged hole until the barrel gets hot. Off to shoot some California Ground Squirrels, good luck.

    Gents, I have had a .308 with 20" barrel for a few years now. 155gr varget and N140 are the go to powders.

    Now I am going to go outside the box following what I have read in the NZ press. Not to be taken lightly I must say.

    Cut the barrel to 16" run a 130gr Barnes TTSX at 3000fps over H335.

    Run the ballistics and you won't want anything else. Sub 300yds.

    I am getting just over 3000fps with 130grain TTSX and (memorably 3.08 grammes) H335 but that is a 22" barrel. How much velocity will you lose per inch of barrel do you calculate?

    45.6 gr N140 behind 155gr Amax giving 2703fps from a 24" barrel. Sorry, maybe a bit irrelevant, but haven't chrono'd it through my 20" which is 1 in 10 and seemed to like the 168gr Amax a touch more although barely distinguishable different group sizes.

    A 130 gr at 3000 fps, you just invented a .270 Win. That is smoking fast for a 16" barrel. Might be a perfect mountain rig? Bet it's a loud beast though.

    That will be a nice shorty.
    I am currently running 125gr ballistic tip 895m/s in my Howa 20" 1:10.

    I must admit I am a little nervous about the chop and will probably go 18" to start with. I will be using an A-Tec Hertz moderator. The over all length of the rifle with mod will be the same as standard 22" barrel. On a Blaser R93 it will be a neat package.

    Google New Zealand "bush pig" rifle and you will fin far more information than I can provide about short barrel and light for calibre bullets. Mainly in .308 and 7-08 but also .260.

    I already have a Thomson Centre Encore .243 with a 14.5" barrel, I do not shoot it without a moderator. I honestly don't know how folk get on shooting them as pistols. They make muzzle brakes seem quiet in comparison.

    I also run the 130g TTSX at 2996 with a mild load of H4895. I believe 3100 would be readily achievable, possibly more. I have heard the 308 loses about 25fps per inch of barrel
