Oh, I always pick the fun ones, lemme tell ya.

So, got a great deal on some 139gr SST's in .284 from Jake over at RMR.

All good so far, right ?

The Mrs. would prefer to give rl19 a swing first. I concur as it worked well in the 145's, and we have plenty of it.

Yep, sounds good again, .....sort of.

Well, here's the hitch :

I have tons of load data using 7mm-08 for 130's and under. 145's and up.

Nothin in the middle.

First step : call Hornady.

Wait 27 mins.

Surprise ! They have no load data. They give me the number to Alliant.

Surprise ! They have none either.


So.....

Here's the assumptive easy question :

139gr Hornady SST
Rl 19
CCI Large Rifle Primers

Anyone got some loading vodou that I don't ?

YA.. I could buy more powder, sure.

I'm not particularly inclined to unless I have to.
*Gently kick/taps box of RL19 containers*


It would be so easy to start at 47grs, and go from there.

I'm not especially excited about testing things no one has done before.... But I guess I'd do it if I have to.

Reloaders Reference v. 9.3x74R shows :

Bullet: Hornady 139gr. Sp Pt.
Powder: Reloader 19
Charge Wt.: 52 gr.
Velocity: 2850
Pressure: 57900

Does not give Primer type or OAL.

This should be considered a MAX load.
The information apparently came from Alliant, however, as you stated earlier Alliant's current load data does not show this load. So maybe starting at 47 gr. and working up may not be a bad idea.

Maybe someone else has more current data to work with.

 

[blarby]

Well, its a start.

Thanks.

From Steve's pages (carefull... he sometimes posts hot loads)

7mm-08 for 139 to 140 gr jacketed bullets

RL-15 From 34.8 grains to 43.0 grains w/ Remington 9-1/2 Primer
RL-19 From 44.0 grains to 52.0 grains w/ Remington 9-1/2 Primer

I included the RL-15, as that's what I'm using.... currently playing around in the 39 to 40 gr. range.

I don't think your going to have much luck with the RL-19. Doesn't seem to be any data published for it in 7mm-08 with bullets this light. Must be too slow.

Have you seen those little manuals that give multiple bullet,powder,mold makers data? I think they are called something like the complete guide to reloading X caliber or something like that. They are cheap and have lots of useful data.

I have them for 9mm and 45ACP.

Given the results in her gun, using bullets only 6 grs heavier...... And in conjunction with my existing supply........ I'm willing to give it the 'ol try.

Probably of no help,but... I've been loading .270 130 sierras with R-19 and have gone to 54 GR with no pressure issue. Nice groups at around the 52 gr.

 

[FROGO207]

A reminder that Lee on their sheets that come with their dies state:

"If you can not find the exact weight bullet you have selected use the data for the next heavier weight bullet. The velocity will be about the same and the pressure will be less."

I have done this in the past when finding a certain propellant was not used with a particular weight bullet but listed for use with others on either side and it has worked well for me. You can generally use a bit more propellant than the heavier bullet calls max in the end if needed but I do not need to all that often. YMMV

 

[blarby]

Well, it works.


I still have all my fingers and toes, and no pressure signs or other obvious bogies.

Standing supported, at 50 yards.

I could never shoot the rifle real well anyway- its hers, not mine.

47grs to start, with cases that aren't fireformed.

Well, we got some fireformed ones now... the rest is up to her trigger finger, and my bench.

And so, "here we go again".

Thanks for the help.
