All my saws seem happy with 40:1, I see no reason to change. It is like using a 165 gr bullet in a 30-06 while some argue for 180 gr and others argue for 150 gr. My ballistic testing showed that bullet construction is more important than wt, so I actually use a 168 gr Barnes.
208 amax FTW

I get excellent accuracy with some of the Nosler bullets, but for penetration, I don't think you will find anything that will compare to the Barnes.
I was reloading my own amunition before, well, still do.
6,5x55, 7x64, 30-06, 375 mag, I simply load with the Oryx bullet. Good accuracy and most important for me, I like the penetration.
Barnes X in s 30-378 though

I presume you are using it for target shooting??? What powder????

300WSM and Rl 22 was a touch over 2800 FPS. On a good day I could keep MOA to 800. I like a lot of the Sierra match king for targets. 69 grain I can keep a 3" 5 shot at 400 yards out of a 16" AR.

Frog lube is best

I had some very accurate loads with my 270 WSM with RL 22 and Nosler BT 130 gr., but they were hot and the Brass was not holding up, so I switched to a lighter load with 4350. Not quite as accurate, but the brass lasts longer. I was getting 5/16" groups at 100 yds with a hunting rifle (I glass bedded it).

I also have a batch of now discontinued Barnes MRX (Tungston Core) Bullets that I save for hunting with that rifle. They shoot very well, accuracy is very good (better than with the all copper Barnes) and penetration is exceptional. They are also shorter, which is advantages in this round.

Sounds like you do some real nice shooting there!

another thing you may consider is whether the brass is of good quality.
You may be surprised how huge different there is in quality brand to brand.
This may have changed since the time I did lots of reloading, when I compared the brands the one I was most happy with where Lapua, Norma on a second place, but in the caliber you have they may not be avaible at all.

btw, that is a nice group with a hunting rifle.

I like the 168 Barnes for hunting, and my 06 groups them in the same place as 165 Rem CL heads, so I can target shoot cheaply.

Contrary to popular believe, penetration is not dependent on bullet wt as much as it is on bullet construction, and the lighter bullets shoot flatter, making it easier to go with a one point sight in for your 250 yards.
