    .303 Pygmy update.

    Hi team.

    Have been shooting the Pygmy with CBE's new 316 175 bullet lately and have changed from W748 to Bench Mark (or BM2 as it is known down here under the ADI banner). I have changed powders as W748 is now ludicrisouly expensive in NZ and BM2 will service my .223 well in addition to the Pygmy and .303 Brit.

    Jim's over sized 316 175 is a great bullet that in WW throws at 177gr, .304 on the nose and .3165 on the grooves so fits the .317 groove barrel of the Pygmy just right. As BM2 is a bit quicker in burning rate than the W748 I have had to heat treat the alloy up a shade and now the clip on WW with 2% babbit is 18 BHN and not 10 BHN at air cooled state.

    Today I shot 22gr of BM2 and put down this 5 shot group at 50m/55 yards. Velocity is 1700fps. The vertical influence was my breathing I believe. Pretty happy with this out of a military barrel on a Lee Enfield action.



    Going to go to 23gr and 24gr next time which will put me at 1800fps + or - which is about as far as I want to go for the sake of case life. I figure an animal hit with a 18 BHN bullet at that velocity range would in trouble.

    Nice group. Iron sights or scope?

    Jeff I'll get mine going next week.The only problem to date is the necks have to be reamed inside as mine seem too thick.I have only fired two shots with a full case off 2206 but I am using AR2219(H322) in the full case for 300mtr shooting and it works so that is what I'm starting with in the shorty.

    Bead front sight and peep rear.

    PAT: I figured AR2219 would be the best powder for it but I want to minimise my powder stocks and so using BM2 gives me a wide range of loading for other calibres.

    What bullet are you shooting?
