150g-168g CB HP for 300BO and .308

[nshumway]

The heavier 203g Palmetto State CB for 300BO don't seem to stabilize or cycle in my 300BO. I don't want to buy a NOE mold for the 300BO if the heavier 247g HP won't stabilize or cycle in my gun.

1) Can I pick up some of those 247g HP cast rounds from an NOE mold from one of you guys to test them?

2) Does anyone have an idea or info on using a 150-168g HP mold for both the 300BO and the .308 for subsonic work?

Since you say a 203 will not cycle your blkout assume you are talking an AR If so what is the barrel brand, length, rate of twist, gas system length (ie Carbine , Pistol) and std buffer or H2, H3
all these will play into what will cycle in an AR at subsonic velocities

PS you will not get a 150 gr bullet to cycle an AR in Subsonic velocities

PS your powders will probably be H110/W296 or Little Gun, Maybe H4198

Might want to sign up to get those NOE 247 HP back on the schedule for production.

anything 200 gr and above will really need a 1-7 twist rate.. a 220 , 230 or 247 for sure

We have several 300BO AR's that stabilize the 245/247 size cast just fine at subsonic velocities. The 1-7" was developed as some 1-8" were having trouble with the very long heavy jacketed bullets, much longer than the cast heavies.

I shot some of the NOE 247's in my 8 twist, 16", pistol gas, AR last weekend. WW + 2% tin alloy, air cooled, PC'd, and sized to .310. I was mainly testing for function so the main difference in the loads was the seating depth. 10.8 gr. of A1680 is reported to be in the 900 fps velocity range. These boolits were on the ragged edge of stability. Had a couple of oblong holes in 20 rounds fired. 11 gr. of A1680 is reported to be in the 1000 fps range of velocity. 40 rounds of this load did not show any unstabilized boolits in my rifle. Accuracy was anywhere from 5" to 3" @ 100 yards with the faster loads being more accurate. I am using a 5 MOA red dot sight. I did not chronograph these so I do not know the actual velocity. I still have to fiddle with the seating depth to get 100% functionality.
If you would like a handful of these to try, shoot me a PM and I should be able to help you out.

You shooting the hollow points or solids?

[Bodean98]

I'm shooting the solids. Sorry, I left out that tidbit of info!
