We will be working on some more 338's soon. Just ran out of 3/8" raw material for the 338's. New material scheduled to be here next week. 2 months late!

Cool, I'm done running ladders with the 210 HH's and am waiting for my turning pilot and Lee FCD to show up this week to see how groups go. Like the rest of us I'm running out of runway to get my loads worked up before I need em!
OK guys (and Gal), I went through all of the pages on this post and extracted what I could from load data for the Absolute Hammers. It is posted in the attached table. This is through page 47 on Sat. morning 9-26-20.
Eventually I will organize it by caliber.
As you can see, some of the entries need a little more info to be complete. If some of this data belongs to you, please add the missing information (about barrel, primer, twist, OAL or whatever). There was one reference to a 6.5 Wby which wasn't clear. I think he was referring to a 6.5-257 Wby, but not sure. I know Tim McWhorter, but don't know what a 6.5 McWhorter is?
When you add additional info., just put it on this blog. I will periodically update the data as it is developed.
Thanks for everyone's input and help. Developing data for new bullets is fun!
NOTE: TABLE HAS BEEN UPDATED AND MOVED TO PAGE 53

Updated my post for the 6.5x284 with 26 inch barrel, CCI250 primers, new LAPUA brass. Also the max powder was 53.7 at 3274FPS

6.5 saum
26 in proof carbon
Adg brass
Fed 215 match
123 AH
Rl16 59gr max 3395fps
Rl23 62.5 max 3404fps
Both of these were max load with no ejector mark or flattening of primers or hard bolt lift. Still could do slightly more powder if I wanted to get shorter brass life. But I like to get 10 to 12 loads on brass.
Hopefully try some more today.

Well I just got some new data for you.
6.5 saum 26 inch proof
Hybrid 100v
61 gr
Fed215match
2.928 coal
3502fps. Groups in the 1s
This is jammed .002 to help get pressure started.
62 grains gave an ejector mark at 3575fps
Now I'm impressed as 3 shots look just like one bullet hole.

Looks like the shooters world precision I just ordered might work well in this. I just filled a case to the neck shoulder junction with some varget and it fit 45.5gr.
Hodgdon load data vs SW with 123 Sierra.
This should get me a decent starting point.
What do you think @RockyMtnMT start around max charge listed for the Sierra?
Edit: max charge listed for varget but with the SW

By the way this proof barrel is on the slower side but the accuacy made me keep it. Not so slow with these.

One thing I noticed on these bullets is if you jam them any amount you really have to push the bolt forward real hard to get the handle to close. I'm only jammed .002 and it's noticable. I shoot .015 jammed on alot of my 1k barrels and never notice it.
Seems like the band that hits the lands doesn't give. That's what gave me the idea to try it to help ignition. Seems to work. .005 jam and I can't close my bolt on it. I am using .0025 neck tension.

It has been suggested that I start a new tread just for load data. That would reduce the amount of "stuff" I have to wade trough. I think that may be a good idea - if I'm smart enough to figure out how.
With regards to everyone manipulating the data, I think I would rather keep it to one person entering data right now. More people = more "cooks in the kitchen" and a greater chance of corrupting the tables or data. This way at least I only have to keep up with one person's errors - mine!
Thanks for the offer, though.
