Those are definately unstable bullets. If you increase the range the yaw will get worse. How short an OAL are you loading? Sometimes and excessive jump to the lands can cause keyholing.

No conventional bullet is gonna expand at subsonic velocity no matter what you do to it. The flat base presented by a reversed boat tail will actually cut a better passage through flesh than the...

The only brass catcher worth consideration is the 3Bucc. It works great.

However it never occured to me to be concerned about the brass deflector being hit by the brass. That is what it is for...

There is lots of data on this website. You will just need to extrapolate a bit and then do some experimentation. Subsonics are fairly forgiving so you don't need an exact load to start with. You...

You will run a HIGH risk of sticking bullets in the bore.

This is both NOT FUN and DANGEROUS. This rifle had a 20" barrel.

I would agree the 125gr BT is a much better choice. Not quite as explosive as the 110 VMAX though but still a good choice.

I can tell you that 19.6gr W296 is too hot. It flattens primers. I am planning to try 19.0gr but that may still be a bit hot.

19.0gr of H4227 works well and produces about 1900 fps.

There is no reason you can't make 147gr subsonics. Just takes a different powder. I have subsonic loads for 150gr bullets using H4227 and H322 that will cycle and AR.

As for 200gr subsonics,...

I will have to try that load in my 10". I was even planning to go out and test tomorrow so I will have to run down to the loading bench and throw 5 of these together to try.

I wouldn't have thought that bullet would be suitable for such a task. It is interesting to hear that it does work well.

What kind of velocity is that load producing?

The very short bullet creates feeding issues. I didn't see any problems related to the large nose cavity. The issues I saw were related to the OAL of the loaded round. The bullet is so short that...

Trying to incease energy by using a heavier bullet in a subsonic is a waste of time. Subsonics penetrate to such a huge degree that even lightweight bullets will overpenetrate any soft target. ...

I looked into these OAL's and while I think there is some merit here, this is not without controversy. These OAL's are VERY short for most bullets. While this may help them feed through an AR15...

Depends on what it is cast out of. Some alloys can be very hard and won't expand at all.

I chrono'd 9.2gr of H4227 at 846 fps. This load fills the case roughly 65% and cycles my 10" Whisper reliably. I plan to try 10.0gr to see what velocity that gives me.

9.9gr of W296 gave 983 fps...

I have settled on W296 as the best powder with H4227 as a backup. These powders seem to be the most reliable with a wide operating range.

208 Amax Oal

Was looking at the 208gr AMAX tonight and discovered something. The max OAL of a PMag is 2.260" If I seat the AMAX's to 2.250" they end up being about .130" off the lands.

I don't suspect their...
