As flat as his curve is with Hunter, I would be a lot more interested in pressure trace data on the loads fired than in replicates of the loads fired over 64 gr.
I suspect those loads are already well in excess of SAAMI max for a 270.
Repeating those loads multiple times is the last thing I would do without working up from well below.

For a thermometer .....hyper velocity federal factory loads with the 110 ttsx did 3350 in my Marlin with a 22 inch barrel. But at least I could reuse the brass on that compared to the federal wsm's which is unusable after one firing...lol.

Which load and powder was most accurate?
Or does that even factor in with you? No. I have good safety glasses and a hardhat.

Exactly, You are not going to get much past 3350 with a 110 gr in the 270 and just about any powder without going well past 65,000 psi.

I'd try 70 grains of hunter over a 150 grain partition. you'll be impressed

Yes, thoughts. Your data shows rifle and MVs without, and with, muzzle brake - but no baseline data for powder/charge/bullet. What could a guy do with that info?
If there is a supposition that MV changed due to installation of brake, can't see data to address that supposition.
If that was not a supposition, am trying to think of a reason for the post.

I don't understand why people try to hot rod handloads over maximum. If the velocity from a 110 Grain bullet is so important, use a cartridge with more capacity instead of loading a .270 over maximum.
And yes, lose the brake. With that weight bullet the bad effects of the excess noise will outweigh recoil.
Don't blame me. I voted for Trump.

What question would you suggest?
Well, we could start with which powder is more readily available, or talk accuracy? But you seem to be preoccupied with speed, so, Turn it up.... Thanks.

Rich, I have plotted a lot of velocity vs charge wt graphs with several rifles and many different powder/bullet combinations.
When a velocity curve flattens at the top end, I know I have reached max load regardlees what the book says.
With Hunter, 64 gr is at or above max.
I would drop back to 55 gr with Hunter and chart velocities up through 64 gr. Then you will have a real picture of where your velocity curve flattens. It might be as low as 60 or 62 gr. Where ever that occurs, that is maximum in this rifle/bullet/powder combination. I like it. That is the kind of thought I was looking for. Thanks.

Fwiw...I've seen some amazingly "brave" Data from Barnes with lightweight/caliber bullets. I recently picked up a pound of Hunter gunpowder and had seen that Data from Barnes but cross-referenced it with ramshots data and was pretty shocked. I realize the extra grooves on a short shank bullet probably help but boys.....double check the Barnes Data!

I've never found a 270 to be such that I'd have to brake one. especially light bullets, but if you feel the need, I see no reason not to.
As far as load testing, i've not seen much of anything here that says if you keep messing with guns, that your head or other appendages will remain attached to your body for all that much longer for the chit you do and continue to do, for not understanding much.
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....

When I die I hope I don't start voting democrat.
