reduction loading.\\\ reloading classes???

[moooose102]

i just had a thought, i know, scarry! anyway, i was thinking of working up some loads (down loading) to 30-06 levels for my 300 win mag. ( it would make it more comfortable to target shoot with, and save a little coin at the same time) what do you guys use to take up the empty space in the case, that will not affect the burn rate, velocity, and won't leave junk in the barrel? i have read on this board where bp revolver shooter use rice, is that for real? is it advisable in modern guns? can i just use straight out of the books 30-06 loads? is there a reloading book that has answers to a lot of the weird questions i ask. my lee and hornay books seem to deal mostly with safety and straight up reloading. i am certainly not dismissing safety, but i think of some fairly odd questions that are kind of off the wall. does anybody offer reloading classes?

NEVER use 30-06 data for the .300 WinMag.
Many powders & charges that are safe in the 30-06 would be way under-loaded, and that could be very dangerous in the bigger Mag case.

If you pick your powder right, starting load data for the .300 WinMag is, for all intents & purposes, a 30-06 max load with a different powder.
And above all, tested & perfectly safe.

No filler is need, or recommended.
Especially rice!

The need for filler is more in very light charges of fast pistol powder, when using cast lead bullets.

Kapoc or dacron pillow stuffing, and Pufflon filler are often used.

All of these fillers will burn in the bore along with the powder, leave no residue, and have no chance of causing a bore odstruction.

I don't think I could say the same about rice!


BTW: Here is some great info on loading reduced loads:

I would be a good place for you to start out.

As for reloading classes?
Cabala's offers them sometimes, but you will find way more experiance & knowledge here then you will from one of thier class instructors.
And learn much more from reading a few reloading manuals!

rcmodel, have you used pufflon in typical straight-wall / handgun cartridges--e.g., 38 Spl, 357, 10mm, etc?

No. I have never used it in anything.
If I were ever to use a filler, it would be the one I would use though.

I did use dacron pillow stuffing in something many years ago, but can't remember what or why!
Guess it must not have been an earth shattering experiance!

Thanks for the quick reply--I've never used a filler, either--but I've looked at it a couple of times, and always stayed away.

However, I have found some nice loads in 38 / 357 with smaller volumes, and I am reasonably convinced I am seeing "powder position" velocity changes in my chrono tests.

So, I was thinking about fillers again.

bottleneck cases are trickier to download for than straightwall cases.

my 8-year old daughter shoots a severely downloaded 300 wsm, which has about the same case capacity as a 300 win mag. what i found...

using something like 17 grains of unique behind 165 grain cast bullets worked and was safe, but accuracy was horrid.

so, i did some research and consulted my manuals looking for a way to accomplish this. what i found was that a medium to medium fast powder (h-4895) could safely be downloaded a long ways. so, i started by taking a 30-06 powder charge, and cutting it in half. went to the range and worked up in 1 grain increments. the lower powder charges shot real soft, but accuracy was bad, i had low pressure signs (sooted cases, primers that looked like a 'pillow' for lack of a better description) and i had a lot of hangfires. as the charge crept up, accuracy improved somewhat, and hangfires lessened.

so far, this is still a work in progress. due to rain, i won't be able to finalize the load for awhile yet, but where i left off i had 165 cast bullets runing about 1800-1900 f/s, and was getting accuracy on the order of 3" at 50 yards. the next batch of loads, i'm hoping will find a load that runs in the 2200-2400 f/s range and will bring accuracy to under 2" at 50 yards. we'll see.

anyway, you might study the lyman load manual - it has a ton of info in it for reduced loads. speer #13 usually has a reduced load option for bigger cartridges using a certain powder (usually the sr-series, but sometimes h-4895).

while i doubt 30-06 data would be dangerous in the 300 win mag, the results will be vastly different because the bigger case of the 300 win mag will reduce 30-06 load pressures quite a bit.

I don't agree, and heres why:

You are probably correct with cast bullets, but Moose102 is fooling with jacketed bullets, and has already had a near miss with a reduced load pressure excursion.

What is the consistency of Puf-Lon? Is it a fiber or more like Super Grex? Thanks

Excellent. I am almost out of my stash of Super Grex.

I looked up the site, but could find no photos of the stuff. Thanks.

jfh - Super Grex works great in .38 Spl, .44 Spl, etc. With lead it eliminates leading and with plated it can give better ES & SD numbers if you want to go through the trouble. I would assume Puf-Lon would too.

That would make a nice little experiment. Might try it. Seems pricey though. Last time I bought Super Grex it was $7.00 for 8 oz or about 350 CC's. Less if you bought a case.

This PSB buffer is what I had in mind to try one of these days.

Just went ahead and ordered some PSB. I will give it a try with lead and plated in some big cases and let ya know.
