Blue dot help

[Blammer]

Ok, I have a 35 Rem and my 210 gr Lead FP GC bullets and 8 pounds of Bluedot...

(well OK, I won't put all 8 pounds behind one bullet.... :D )

Anybody have a load recommendation?

I can't seem to find any for this combo.

What other powders do you have? ... felix

Blammer: Bluedot may not be the best choice, but since you have 8 lbs of it, why don't you start with 15 grains and a large rifle match primer of your choice. Check the chronograph and adjust up or down until you get to about 1500 fps or whereever accuracy seems to peak at. That sweet spot will also be influenced by your twist rate and the hardness of your alloy. If that doesn't work out, try SR4756 at about the same 15 grains. - CW

I found BD to be very position sensitive. My experiance with it was with a 30-30.

Generally when working up Blue Dot rifle loads for which there is not available data, I start with the Unique maximum charge for the same bullet and work up from there. I'm not saying you should do it that way, just that I have.

To me blue dot has allways been a very pressue sensitive powder and i dont use it for anything anymore. It goes from mild pressure signs to wild pressure with a small increase in charge weight. I dont think id bother with it in a rifle case it wasnt designed for. there are two many other good powders out there for what your trying to do. I wouldnt trust it in a rifle case and i doubt if it would burn very consistanly used like that anyway. I may be wrong as i havent done it but then i never would to find out

Blammer, Go over to the Accuratereloading.com forum -> Reloading and look up Seafire. Ask him to send you a copy of his Blue Dot rifle loading data (based on jacketed bullets). You should be able to extrapolate a safe load from it.

[Blammer]

thanks! I'll investigate a little more, thanks for the tips!

I have about 30 other different powders so choosing a suitable one is really not a problem. I was just wanting to use my "HOARD" of Bluedot.

If someone was close, and could meet in person, and wanted too. I'd trade a pound or two for stuff.... bullets, powder, or primers.

Blammer, when you come west on your vacation, bring some BD with you. I will take or trade all you want to bring. ... felix

Have used Bluedot in .222...223...30/30..308..303..30/06...338 win mag..444 and found it to be one of the best reduced load powders available. Groups with J bullets at 100 yards of one inch or less were achieved in every caliber... and in the .30 cals from 110 gr to 180 gr. The data I used in each caliber was courtesy of Mr "Seafire"

"Seafires " premise was to start at 40% of empty case capacity and work up one grain at a time towards the 60 % mark as the usual max when he'd get some bolt resistance and sometimes extraction resistance and after that one grain more would usually blow a primer.

" Seafires Data" In 30/30 with `170 Hornady FN .. Model 94 Win.

7.0 grains....1009 fps
8.0. grains...1078
9.0 grains....1153
10.0 gr........1277
11.0 gr........1389
12.0 gr........1473
13.0 gr........1555
14.0 gr........1597
15.0 gr........1685
He states he went higher and had no problems but felt 15 grains was a good safe max for everyone...
To my knowledge the 35 rem was not tested as he only did calibers that he owned a rifle in.. The 40 to 60 % rule work up should be good for your 35 rem regardless of boolit weight with cast.

I realize there is a vast amount of knowledge here from a lot of people. BTW, I was not going to post on this but I have been down this road before, same subject same person,aka seafire. I don't know the fellow from Adam, don't know his back ground. I did ask a few questions at AR and never recieved a reply as to what he was using to check pressure and pressure curves, etc. There are way more positive ways this day and age to measure pressuure and primers and web stretch don't quailify.
The data is out there, but I will not point ANYONE towards it. I have talked to friends at Hodgdons and Sierra, they didn't recommend it and said to enter at your own risk, good enough for me.
Statements like
"He states he went higher and had no problems but felt 15 grains was a good safe max for everyone"


" he only did calibers that he owned a rifle in"

Sorry gents, a 7mag and BD??????????? I am tight but I ain't quite stupid and tight.
This is not an attack on any one here there or yonder. I just feel this is one subject that there is NO discussion, period.
I have said my piece and will not respond to ANY more on this what so ever.

Be safe,
Jeff

[Blammer]

JSH- you make good points with good reason! no problems here with that!

I ain't out to wild cat, if there ain't some "reputable" reloading data, I'm REALLY not terribly interested in it.

thanks for all the info guys!

[hs45/70]

Mr JSH......

Your opinion on the values of Bluedot in rifles is noted....
Those of us that have actually worked up loads in the various calibers useing this mans' data appreciate the time and effort he went through to arrive at his findings so that we could benefit.

*****This .338 win mag data is not reccomended as it's not in any manual*****

Ruger 77 .338 win mag 24 inch brl. 9x scope ww cases and mag primers

200 gr. Hornady spz.
37.0 grains Bluedot...2424..2444..2433 fps...0.75 inch/100 yds

250 gr. Hornady spz.
35.0 grains Bluedot...2169..2132..2122 fps ...0.95 inch/100yds

265 Lapua RN
33.0 grains Bluedot...1965..1952..1964 fps....1.10 inch/100yds

To use Bluedot or not in rifle cases is everyones own decision... and if they're not comfortable with it as it doesn't appear in any reloading manuals then I'm sure they will heed your advice....never tried it in a 7 mm mag as I don't own one.

cheers........max

The operant criteria here is pressure. BD is a shotgun powder, and does go ballistic when ran to pressures higher than it was made to operate at (is this where the duh! goes?).

My GUESS is that 20,000 psi is safe, that or below (my guess only as some of my loads with it may have been that hot). And I love the h#!! out of it in hot pistol loads for the lower pressure pistol ctgs, and reduced loads in others.

There is pressure data for BD in several manuals, Hodgdon's primarily, it should give you a good idea as to what max pressures should be, and what to avoid.

AA#9 is in the same burning rate (some slower), and makes excellent reduced loads in fire breathers and doesn't have the pressure limitations as it will almost equal 1680 velocities in ctgs like the .454.
