Anyone have any load data for this? Using Winchester 760 powder?

Hodgdon has published load data for Hornaday 190gr jacketed BT, why not use the start load there and work up, like you would anyway.

[atdski07]

I guess I could, my hornady book shows a start load for 178-180gr at 38.4gr@2000fps, and for 190gr it shows 37.5gr@2000fps, do you think it would be better to load to the 190gr data and work it up or the178-180gr data? Also thanks bill you the man, always there to answer a question

I had my Hornaday #8 on my desk, so it was easy for me to cross check.

They list 180gr Jacketed for 760 at Start - 42.3gr for 2100fps, Max - 53.2gr for 2600fps

They list 190gr Jacketed for 760 at Start - 42.8gr for 2100fps, Max - 49.7gr for 2500fps

Maybe start at 42.5gr and move up in .5gr increments til you find a good node or start getting a heavy bolt lift and/or flat primers.

Good luck, have fun.

I'm looking at my hornady #8, what page? I'm looking at page 495-496

Oh I see, your looking at the 7.62x54mm R data, page 508-509

I think I'll work off the 190 gr 308 Winchester data

Sorry bud, wrong page. Anyway, I think taking the 190gr load data and working up will work fine.

I have found the Hornaday load data very conservative for 308 Win. I thought it was a general lawyering up thing, but some of the handgun calibers I load are actually quite stout in the #8 book, so I think it was just a hot day in the test chamber the day they did the 308's.

Got Varget?

The U.S. F-class Team is using the 185 Juggernaut at 2750-2850 fps with lots of Varget. The results are quite impressive.

I shoot 185gr Lapua Scenars and LockBase, if you can find VV-150, it's worked well for me, if you can find it.

You can split the difference between the 180s and 190s, FWIW.

H322
RL-10x
A small amount of RL-15(saving for 75gr 223)

I've notice this too, the 168gr .308 I loaded with RL-15 were only starting to group decent at 42.5gr and for RL-15 it states a max load of 44.3gr. I worked those up from their min. Load of 35.2. What a waste :-/...

Ok so I'm splitting the difference on what my hornady book says, at 2200fps both say 42.3-42.4, with this amout of powder I am starting to compress the load using the 190gr C.O.L. of 2.745". I'm not sure what to do. Most of my brass(all fl sized and trimmed to 2.015) are LC head stamped, a few gave SBS head stamps and WCC head stamps, the majority is LC.... Help....advice.. Please

Dude, where are you getting a COAL of 2.745 for a 190gr HPBT?

You sure that's length isn't for some round nose hunting buller?

Try seating out to at least 2.805" and depending on your leade/throat length (and magazine length) 2.840"+, even with the 185s.

2.745" for a flying dart is way too short and you're chewing up case capacity in doing so, not to mention potentially spiking pressure.

I do have one with a 308 win head stamp, the same charge goes to the same height in the case, from what I can see, does not state that its a compressed load.
