Don't know anything about reloading

[fishfinder]

Wanting to load up some 300blk. I have a friend that is experienced in reloading I figured I would buy the materials to do this. Am I right that you use a trimmed 223 case? What kind of powder? Anybody got any for sale? Is there a website that tells accurate reloading specs. My reloading has been nothing more than shotgun shells. Thanks

Jedi Marcus or Rumbler will be along shortly...they sense a tremor in the Force.

If you really want to start reloading do yourself a favor and go get a book on reloading. Lyman, Speer, Lee, ..., whatever. Read it, and read it again. Learn the process (it's not all that hard) and then start slowly with dies, presses, case gauges, ..., etc. Once you have the basics down you could also arrange a field trip to DSH and one of the reloading sessions they put on. It'll make your life easier.

Finally listen to those like Master Rumbler and Master Marcus. It's extremely satisfying to punch holes in the 10 ring with ammunition that you made yourself. Enjoy!

Coach.

Thanks for the advice that's what I needed to know.

Marcus sells cases that are ready to load for$20 a hundred I think. If I were you I'd just buy some from him to start loading. You can always start forming cases after you learn to reload. I've been reloading for more than 40 years and all though I have the equipment to make my cases I just buy most of them. It saves a lot of time when you start with cases that are processed and ready to load.

Since you are new to cartridge reloading, I highly recommend the ABC's of Reloading (www.amazon.com/ABCs-Reloading-Definitive-Novice-Expert-ebook/dp/B004GUSBP6/ref=sr_1_1?ie=UTF8&qid=1421853796&sr=8-1). Visit your friend and get some time behind the press reloading cartridges. Also go by DSH and check out their classes. Ask lots of questions.

Then get at least two reloading books. I've enjoyed the Lynman and Speer books. If you pick up a copy of Hornady 9th Edition, there is some errata with the .300 BO data (http://www.hornady.com/assets/files/9thEdErrata.pdf). In addition to two reloading books, pickup a copy of Lynman's AR Reloading (http://www.amazon.com/Lyman-Reloading-for-the-AR-Rifle/dp/B00I6OUTXK/ref=sr_1_1?ie=UTF8&qid=1421854124&sr=8-1). It probably contains the most recent published reloading data for the .300 BLK.

If you do decide to make your own brass, here is a overview of the process: http://imgur.com/a/bluJu. It isn't difficult, just time consuming. Pay attention of the GO-NO GO link of acceptable brass referenced in the guide. This is very important because some brass is too thick and can result in chambering issues at the neck after the bullet is seated. I also use the Harbor Freight Chop Saw (http://www.harborfreight.com/2-in-mini-bench-top-cut-off-saw-61900.html) and Jig (http://www.300blktalk.com/forum/viewtopic.php?f=179&t=80842). Our load HF carries the saw from time to time. Also note that he uses stainless steel wet tumbling and a W.F.T. to trim the brass. You don't need those to get started but they help speed things up. I'm still using dry media and a hand trimmer...but I'm going to be getting a W.F.T or a Giraud trimmer very soon for 300 BLK.

The best tool for .300 BLK reloading that I can recommend is a Slotted Sheridan Gauge. Here's a summary of everything it does: https://www.youtube.com/watch?v=OKyM4O4vsWg. Even if you don't make your own brass, you should get one to check your final product. It will save you a TON of time if you get something wrong.

Powders: the holy grail of .300 BLK powder is Accurate 1680...but it is made from unicorn blood and really difficult to find. I would be on the lookout for Lil'Gun, H110, and Win 296. You can also use IMR 4227 for supers but most loads end up being compressed.

Be sure to check out the the handloading section of the 300 BO forum (http://www.300blktalk.com/forum/viewforum.php?f=141) for tons of reloading data. Just remember that the data posted is for their gun/configuration and may not perform the same way in your gun. Either start with the min load in the manuals or reduce the max load by 10% and work up.

Bravo! Thanks, Jason !!!!! :headbang::headbang:

BTW - That Slotted Sheridan Gauge? Easily one to the top inventions of the 20th AND 21st century.

We'll I have a good friend that has been reloading years sells custom loads. I'll be letting him do the dirty work just watching and learning. I'll have to see if I can get cases thanks for everybody's input. Like I said don't know shit about reloading rifle ammo, but I'm trying to learn a touch, enough to be dangerous.

Reloading for the 300 BLK is quite easy once you have the cases. I would say get the Lyman manual. Lots of good info there and what I started out with in 1972. Also, join up with loaddata.com. Well worth the money. They have most of the manuals and info from Handloader and other magazines.
