The 210M will light off RL25, Retumbo with the low load densities just fine, no hang fires or flashovers. I used them down to 10-20 degrees F. and they still work excellent in the 300 Ultra and the 30-338 Lapua Imp.
I did have a hangfire at the range the last time out, two of them, but I was testing 84gr RL22 with the 200 Accubond in the 30-338 LI.
Try the 215m and 210M both, they do change the pressure and ES and one will be better than the other. Some loads the 210M lowered the pressure, some it raised it slightly.
JLK's aren't made in .338, .30 is the largest.
Just to clarify - My throat appears to be for the shorter, lighter pills,..as the base of the 210gr berger is below the shoulder/body junction slightly. Is the bearing surface/boattail juntion (heel) below the neck/shoulder junction and this is what you're refering to, or is it at or above the neck/shoulder junction and it's like you said, the base itself is only below it?
What is your OAL with the 210 Berger with it seated right to the lands?
I loaded some 210 JLK's the other day and the OAL was 3.897 to land contact. The 200gr Accubond was 2.835. I haven't tried the Berger in it yet, but the JLK looks promising.
You're not as far in as I thought you'd be, but if you're shooting the 240gr SMK that's holding them in pretty deep, was even for mine with a 240. I think throating so the heal is about .050 - .075 above the neck/shoulder junction is about right, just enough to keep it out of that pinch point area.
Bounty Hunter,..with the 210 berger VLD right at the shoulder/neck junction,..I should be good to go with the 216gr clinch river bullets,..don't you think? Or will they be too deep?
also,..the throat reaming tool you mentioned,..have you ever used it or know anyone who has? was it as simple as they say? is there any chance of creating a non-concentric cut,..in which case I should just pay the gunsmith??
Thanks again for your help so far guys.
You try to get closer to the target,..and I keep trying to get further away.
