300wm 125gr speer TNT load data?

[hillbillydruggist]

if anyone would like to send me a message with some load data I would appreciate it. I have the following powders,
IMR4350
IMR3031
IMR4064
IMR4227

of course I would not hold anyone liable for the data, thanks

Nosler lists 75.0 of IMR4350 for their 125. I found a stout charge of H4831sc was also very fast and accurate.

I did this many years ago in my 300WM old Ruger MK II with those bullets.
I did not read the box, it states not to exceed 3100fps.
After firing 5 rounds and looking at the target, there was not a single hole in the paper, ANYWHERE.
Asked a fellow to spot for me, he said there was a blue/grey puff and a streak about 30yrds out.
I switched places and watched while he shot, yep big blue/grey puff about 30yrds out. Dunno the exact velocity, but it was a max load with H4350, must of been above 3500fps I would say.

All I can say is don’t push ’em, they don’t like it.

Cheers.

Yes the jacket is thin and they will sling themselves apart at high velocity.

I run them in my 25", 1-11 twist 300wm at 3525. They group great and i have yet to poof one before i hit the paper. But actually, mine are the Nosler BTs and Accubonds. I haven't tried the TNTs. Hope this isn't confusing.
