You can shoot up to 220gr as subs as long as you run the round nose bullets.Form generators to include forms 1, 4, 5, caliber changes, registry removal, and many more to coincide with NGT’s form guides. Unless you intend on only shooting specialty machined copper expanding petal type subsonic projectiles and believe the marketing around the rotational energy of such bullet killing game any better than a subsonic soft lead cast HP or a tumbling after impact long 240gr SMK then dont bother with anything over 1-8" twist.Ī 1-12" to 1-10" will actually shoot a wider range of subs and high velocitie bullets better than the 1-8" and 1-7". The slower twist also combats bore leading. They are a short bullet with a blunt nose and base so dont require a fast twist barrel to stabilize them. The best twist for that cast 151gr HP at subsonic speeds is a 1-12" to 1-13". Lighter bullets in a fast twist don't nessisarally shoot slower than a slower twist will but do reach pressure faster which can in turn effect final achievable velocity. If you are using cast lead in a 1-7" you will also get a lot of bore leading which also destroys accuracy. 308 with the all the longest and heaviest bullets available such as the 240gr SMK. 308 were designed for use with the heaviest and longest jacketed bullets to run at subsonic speeds.ġ-8" gives the best subsonic accuracy in. I totally agree with Friwi, all the best accuracy I have achieved with both subsonics and high velocity was a twist rate of "just enough" and faster twists barrels groups have always opened up.įast twist barrels in. The team down in the butts nic named it the bumblebee as the bullets whizzed over with a deep buzz at sub speeds rather than the sharp crack they were used to. They were still perfectly stable and grouping well with round holes at 1000y. 338 Whispers ran 1-9" twist Shilen and trueflite barrels shooting 300gr SMKs and 300gr Berger hybrids at 1040fps MV. Ask Wingman what was the twist rate of his 338br and what projectiles he was shooting subsonic and how they where flying.My.
