Thank you Sir!

Yeah, looking at the vids, it does look to me like you are getting your energy dump earlier in the stack. It's hard to tell definitively from just a youtube vid, but I'd say you are right.

Pics of modified bullet?

Forgot to get pics of that- I'll get some next time. It was just a 3/32" x 1/8" deep hole drilled off center in the lead tip.

Thanks for all the hard work TXgunner and Rapier. This will be good info for many to start from in developing SS loads for their rifle. From working with 2400 in the 8x58RD and 190gr GC bullets I thought maybe you would be able to get that powder to work well in the Grendel as it is not position sensitive and ignites well. Have you noticed any powder position issues with the IMR 8208XBR since you lengthened your COAL?

[txgunner00]

No problem.

The longer COL seems to actually burn more efficiently as the cases come out cleaner.

2400 may work in some rifles. It's all about matching peak pressure to the gas port position.

For another data point........I loaded up some Hornady 160gr RN bullets with 14.0gr of IMR 8208 in NEW AA cases and CCI 450 mag primers. Seated the bullet around 2.4" and fired away. All 5 rounds cycled the action in my 16 inch chrome lined Saber AA upper. Velocity was a bit high at around 1200 fps so I need to back the load off a bit but it was fun and accurate. Looking forward to the next experiment.

Good to hear it's working for you.

2.4? Really? 2.24?

[Smokepole50]

Yes Bill you are correct. I was in a hurry when I typed that or at least that's my story.....)

The actual OAL was 2.238"

Thanks for catching that slip.
