CFE223 is the main powder I use in the 308. It is supposedly very sensitive to temperature. I can’t say that I’ve noticed an issue but admittedly I really only use my 308 for hunting and I only did load development work when temps were about the average temp that I hunt in (50deg +\-).
I’m...
DrMike,
Would you mind running g 2 more bullet combos in the 30-06AI? 175lrx @ COAL of 3.547 and the 200lrx at a COAL of 3.675. Both at the same max pressure of 64k and 24” barrel
Thanks in advance
Matt
Aussie, DrMike would have to run the numbers to get exact but I think it would greatly depend on what you meant by the “Standard” 30-06. If you mean stock off the shelf where you have a max COAL of 3.34-3.4 then I’m guessing there would be quite a bit. First a stock gun is likely to have a...
I’m thinking the same thing. Originally I was looking at the 175lrx and the 200AB(if I could ever find any) but as I started down the rabbit hole with the 208 more just out of curiosity.
I was looking at down range velocities with my original guess of 2700. At 5000ft elevation the 208...
Good morning, I was wondering if the barnes 208 LRX is available in QL yet and if so would someone mind running a couple different things through for me. Not really sure what the table is called but the one where gives you the table of approximate max charge for different powders.
I’m...
I found this a couple years ago, I don’t know how often they update it but the list has definitely grown since I first found it. Lots of great info/testing on defensive rounds. Now this is all towards 2 legged attackers, if your more focused on defensive ammo for bears the probably not a...
That is basically my plan. COVID-19 has put a major damper on my range time. But once everything calms down and we settle into whatever the new normal is I plan on testing the 168s to see if they are stable in my 1in12 twist. If they are, I am going to try pp2000mr. What I have read is...
I’ve never played with etips but I use barnes TTSXs almost exclusively. From what I have read etips like a bit of a jump.
From what I have seen with TTSXs the pressure curve for a given charge seems to be shaped like a bathtub. As you change seating depths off the lands. Really close it...
I have the 2.5-8x36 VX-III on my M70 featherweight and like it a lot but sometimes I wonder if I should have gotten the 3.5-10x40 VX-III. Although I’ve never had an issue, the 40mm obj would allow for a little more light transmission and the 10x would be a little nicer for longer shots but I...
Varget is always a good starting point with the 308. It is extremely temperature stable but produces a little less velocity. CFE223 gives you about 100fps more for any given bullet but is a lot more sensitive to temp fluctuations. I have been hearing great things about Power Pro 2000-MR...
The Partition is a great bullet but are generally much shorter then other bullets in the same weight class. Which may have an affect on accuracy depending on the throat in your rifle... I would suggest either the 165 accubonds or 150 Barnes TTSX.

So I’ve made a couple trips to the range to do some pressure tests.
First trip I loaded up 2 -15 round (1 varget and 1 CFE223) strings with 168gr TTSXs sitting .05 off the lands and a COAL of 2.995. I saw no pressure with the varget string and it topped out at 2743 and the CFE223 showed...
