Did some chrony shooting last week and thought you might like the results of my .257 weatherby.
76 grains of ramshot magnum under the 100 grain tsx barnes. Lit with a federal 215 M. velocity was 3550 from my 26 inch remington tube.
Just about what I was hoping for. Also shot my tried and true Roberts load of 46 grains H-414 with the same bullet lit with a fed 210 M gave me 3133 from my 20 inch ruger.
And last ,my custom JC-Higgins 30,06 put a 165 grain hornady interbond out of its 22 inch tube, at 2815. Pushed by 60 grains of RL-19. And the FED 210-M
I am very pleased with these readings, but I might try to push a little harder with the 06 load.
I have seen published loads of 62 grains. I would be extatic to get another 85 FT or so with a 165 from a 22 inch 06.
Switch to a 168 grain TSX , and get somthing like 2900 FPS
and the killing power would make my 06 a better elk rifle then a plain jane 300 win load.
At least in my mind it would !

I used mule deers data on the 264 win, and am getting right at 3200fps with a 142 smk from my 26" 264 win using 69 grns of ramshot mag, also tried some magpro in the 264 and 270 I think it will get the speed I need from the 264 if I need it to, however in the 270 win magpro can really dole out the speeds, I was below max recommended working my way up, and I got to a point where the speeds where getting ridiculous, I had to stop halfway through the 10 rounds I had loaded with different increasing charges, because I was going to exceed 3300 fps with a 130!!! I am gonna go back and try my starting load as it was already at 3167, which is about where I wanna be

My 257 Roy loves Ramshot Magnum. I've fired 9 different 3-shot groups with charges ranging from 71-75grs and the average group size from all groups is 1.030" with a best of 0.273". 75grs gets 3568fps out of my 25.5" Rock Creek barrel.

Wait till you have a 40 degree temp change and watch what happens to your loads using Magnum.
I no longer use the powder.

Dangit, I thought R22 was supposed to be the temp sensitive powder...

Thanks, the smith deserves most of the credit as the rifle shoots every load I've ever tried very well.
As far as powders and temp sentsitivity goes, I'm into research not rumor.

So you shoot at 10 degrees and run a table based on 70 degrees and all the sudden the powder is no longer temperature sensitive.
I think I am missing your logic.
I think your "research" should be shooting cases/reloads that are at 70 degrees and shooting cases/reloads that are 10 degrees and measure velocities/ES/horizontal dispersion difference between the two.
Just me though, sorry if I am way off base here.

I ran the table @ 10 degrees based on the data I acquired at 10 degrees. I shot the table @ 70 degrees, horizontal dispersion is pictured on the 1st page.

Those are some great groups at a K using a 25 caliber. Impressive.
Here are my 3 shot 100y groups shooting a 6.5x284 out of a 700 Ti using Magnum powder at 85 degrees. This same load went to crap and started shooting 5" groups when the temps went to the low 40's. My velocity also was off by 60 to 70 fps.

Bob- did you play with this more or was this a one time thing? I didn't notice this with Magnum when I played with it but if the differences were subtle, I might not have picked up on it. I have limited experience with Magnum but TAC is FANTASTIC. I have had great luck with Hunter and Big game but have not used them enough to get render a valid opinion. In it's burning range, I have never found a better powder than TAC. Won a BR match with it in fact.

Dennis, No this was not a one time thing as I was obviously dissed
that this load may not work for me. I checked it multiple times
hoping that it was me or the rifle or? Not to be.
Also, JB, if I recollect correctly has commented that out of the Ramshot herd, Magnum is the only one that is temp sensitive.
I thought I had found "thee load" I ended up switching to 7828 SC.
