150gr Subsonics for AR15

[Suputin221]

I am also interested in this loading as I have some 147gr m80 and some 150gr. Any one have a ruff idea where to start with lil gun or h110 or trailboss for these bullets. I will be shooting them from a remington 700 and through a yhm phantom m2. Thanks

For a boltgun, 6.5gr of Trailboss is the only way to go. Ludicrously quiet.

That's what I was wondering. I have heard 5 grains under a 125gr. Just wasn't sure where to start with the 147gr m80. Thanks I will give that a try.

Now im gonna have to get some 147grs to play with the TrailBoss too...really like the lighter rounds, but need loads for variety...gonna try some A1680 ones and maybe some 4227 too...

What oal with the 147gr and trailboss?

[VinnAY]

I'm gonna try some in the Leonidas as well, I got that powder laying around. 1680 works too, yeah?

A1680 is working for me

How's aboot some load data? 11.5gr?

How about with 147s? I found some cheapo ones, can get 150s for a bit more if I need to.

147-150 the difference is almost nil, there's absolutely no need to choose one over the other due to weight.

subscribing so I can listen in...

What oal with the 147gr and trailboss?

Trailboss will fill the case right to the bottom of the neck. OAL is gonna depend on the bullet. With the Hornady 150gr I am at 2.180".

Grrr, how did we get back to bolt guns? They'll cycle anything!

1680 and Lil Gun are much louder through a can.
