Case primer pocket and base will hold up better and allows for higher pressure without beating up the brass. I'll send you 20 for free when I get my shipment of 250 if you'd like.

That's a really generous offer! Hold that thought. The only srp I have is fed205. Ok to use? (Do have fed205gm and #41, but not currently wanting to deplete my stash.) Are powder types/requirements published?
No need for specific load data published, just know that you can usually run a hotter load usually and primer pockets last longer. Any of those primers will work. Some even run SRP magnum primers. The load with the 150 BD that @nralifer is running is using SRP brass and I believe he's running magnum primers. Too bad you weren't closer as I could throw ya some primers also.

Now don't start offering to throw "gold" around. You'll get LOTS OF TAKERS! I'll get back to on the brass offer via pm, if that's ok?
My sentiments exactly. BTW, my gun decision paradigm is the same. It works for me well. Milage may vary.
Just let me know.

I run 46.5gr Benchmark under the 130 TTSX for 3,140fps in a 22" bbl. Accuracy is surprisingly good with 3-shot groups regularly coming in under 2" at 400yds. Whitetails prefer that I don't use this load. LOL

So sorry to hear that. It's tough losing a good friend

How about some more information on your load. Barrel length, powder used, twist rate, brass used. The 2021 Hodgon data from a 1:10 twist barrel 24" long for a 3006 shooting a 208 gr Amax ( max speed = 2660 with SB6.5 powder) is about 230 FPS slower than what you are quoting for your '06. Something is not right.
The 150 BD2 from my 308Win using LVR out of a 24" Bartlein 1:9 barrel will go 3180-3200 FPS.
I think he may have some of the data you're looking for in post 887.

Last winter, on the range, I had confirmed drops every yardage through 1200. At 1200, 9.6 mils was spot on for center mass on eSilhouette.
Rifle details here. One thing the 215 got going is the short bearing surface.

Rifle: 28 inch KBI 10T Serengeti chambered by me SRS Ti Pro 3 ST Trijicon Tenmile 700 worked over by me. Loading and shooting on the range worked out a load with N560 and 215 Berger Hybrids. Pressure test at .5 grain increment topped out at 60.5. Initial results with limited data precision node...

I thought your numbers were from a standard 30-06. The 30-06 Serengeti has chamber that's different I take it but still allows standard 30-06 brass to be used?
Yes, the LC 67 Match I used were fired from 03s, and NM M1s. I just annealed and FL sized them, then uniformed primer pockets, deburred flash holes, and skim cut necks.

This post shows an optimized 3006 load shot from a long 28" barrel, high energy double base powder in a non-standard chamber. It does not represent a standard 3006 load or chambering. Nevertheless the post is analogous to what I was trying to illustrate in the 308 Win. Your data is very nice and illustrates how much additional performance can be squeezed out the 3006 when powder and chambering are optimized along with a high quality bullet. You could further optimize it by using a lighter bullet (205 gr .308 SBD2) shot from tighter 1:8 twist barrel. The 205 gr bullet has significantly higher BC roughly equivalent to the 230 gr Berger. The 308Win loads I was talking about used a barrel 4" shorter and more suitable for hunting because of the more compact rig. The comparison of the 308Win to the 3006 was data from a production rifle using lower energy powders in the 3006 published data from the 2021 Hodgdon Annual Manual. The optimization of the 308 Win was using a 175 gr BD2 (G1=0.605) bullet, Lapua Palma brass that can withstand higher pressure because of the SRP primer, and the high energy Leverevolution powder. Both your data and mine illustrate the same point, that being that a significant amount of additional performance can be unlocked from either cartridge when component selection is optimized.Last winter, on the range, I had confirmed drops every yardage through 1200. At 1200, 9.6 mils was spot on for center mass on eSilhouette.
