velocity survey

Well, I was looking to shoot these loads out of a 16" AR. 50,000 CUP sounds like a lot of chamber pressure, am I off on that? I'm hoping to get a chrono pretty soon after getting the 300/221. So I'll just have to do some trial and error. Do you guys think that a load like the 150gr Nosler at 2400 fps would be better for hunting deer and hogs, or a heavier bullet like the 240 at 1100 fps?

That pressure level should be fine for an AR but you would start low and work your way up just to make sure looking for flattened primers and case head expansion. For deer hunting around here we use 150 - 180 grain bullets. One of my favorites is the Sierra 165gr HPBT for an accurate hunting bullet and it has dropped a few deer.

For pressure most max AR loads see around 50,000 CUP or 55,000 PSI. That is just an observation so watch your cases and measure for yourself. I am not sure you are going to see 2400 fps with a 150gr bullet but you can work it up and see what happens.

No- I do not think you can get a 150 to 2400. I like pushing a 125 for deer and hog much better than a 240. You can clearly use a 240 but it is all about shot placement and knowing the ballistics profile of the round. If you have never shot subsonic there is a fun learing curve that mimics the trajectory of the round :) heck the point of impact difference from 50 to 100 yrds is @4" which is not something the average rifle shooter is used to.
