Anyone have a good starting point for my M1A
Anyone have a good starting point for my M1A
Not with H 4895, but with AA 2230 & H 335 and the RCBS 200 Sil.
IHMSA # 566 "time sure flies when you're having FUN"
I started with 21.0 AA 2230 with the 200 gn RCBS Sil. & 311299 cast from WW & water dropped.
The RCBS drops at .310 and the 311299 was lubed & sized .311
Cycling was slow.

29g just cycles my FN FAL and Saiga 308.NO filler and good with 160 to 200g bullets.About 2 MOA accuracy with not alot of work.

That look on your face, when you shift into 6th gear, but it's not there.
Also, with 10 minutes of google, I was able to find some more H4895 load data using a 200 gr. bullet. Just saying. I believe it's best to do the research before accepting random loads with a given powder.

Not many manuals have starting loads for operating 308 gas guns and cast bullets WILCO.Asking here is a not a bad place to start.I rarely refer to load manuals any longer.I know the basic ranges for the cartridges i shoot with low to mid range cast bullet stuff with the 4 or 5 powders i use.I have 3 Little Dandy's set up with charges i make work with many of them.I do it reverse of others.I pick a power charge and see hat i can get it to shoot in..I wont give out loads data of the top of my head to others though.

There is no Lead 200gr in my 2ñd edition. Jacketed yes. 38gr starting. I knew that was way to high. I really didn't appreciate your "get a manual" comment as I am a little beyond the need for a lecture from you. Then to have you tell me to use Dr. Google instead is even sillier. I trust the people on this forum way more then Dr. Google. All I wanted was a starting load for lead in a M1A. Something that didn't work the action so that I could work it up to a decent point that did work the action before a made a bigger batch to fine tune it and chrono. I only trust enough to use this as a partial verification of how low I can start. Not how I I can ultimately push it.
Page 147 of Modern Reloading, 2nd edition.
Listed under the following: “.308 Winchester Cast Bullet Loads”.
I’m not interested in lecturing. I only wish to educate.
Getting another manual was mentioned because the pertinent information is listed in the title I referenced.
Google was mentioned because it can lead you right to the source of solid reputable information from the manufactures. Like this link here:
http://data.hodgdon.com/main_menu.asp
While the good folks of Castboolits.com know a great many things, they are not the manufactures of powders. You’re much better off trusting the likes of Hodgon, IMR and Winchester when seeking load data.
It really doesn’t matter if it’s full metal jacket data, because if you read your Modern Reloading, 2nd Edition thoroughly, you would know that on page 157, it tells how to safely calculate reduced loads for lead bullets. The 1st Edition has a formula to reduce powders using simple high school math. Also, the LEE Shooter program has the ability to do this, though it works best with Windows XP.
You cannot walk before you crawl. It’s dangerous to endeavor a task without fully understanding the parameters of the specific load data and powder to be reduced.
One thread reply mentioned Dacron. What do you know of “Fillers”?
You have a valid point George, and as I’ve mentioned before, I’m not interested in lecturing. I only wish to educate. I’m a major proponent of studying manuals and gaining a solid foundation of the basics before one attempts to go forward with the more technical tasks in load development. As we have seen in this thread, the OP is searching for load data, took issue with my replies and ended up having the answers he sought all along. His only roadblock to success was his failure to read and comprehend the information he has at his disposal. That is both disheartening and scary, as it seems to be the more recent trend with a whole new batch of “Reloaders” coming on scene.
Colorado4wheel, best wishes as you go forward.

The internet site from Hodgon gives 35.5gr at 2250 fps.
I did not expect Lee to have a separate LEAD only data section of their manual. That was helpful thanks for pointing that out. I read that manual 6 years ago and remember his comments but forgot his having that data in the earlier part of the book. His comments are one reason I even considered loading lead in my m1a.
The rest of your post is pure "I know better then you and your wasting my time by posting on this forum and not finding the answer on your own" You may not think that is how you come across but it surely is in my opinion and your comments could have prevented other good folks from helping me. Forums are meant to be helpful not "Learn how to search you idiot". What I wanted (and got)was the starting load some people used that was really light in the m1a. Something that was below most book and didn't really run the gun. I had researched and thought it would be in the high 20gr range but now I know I will start even a little lower.
Feel 100% free to put me on your ignore list.

You completely missed my point about reducing full metal jacket loads to cast boolit velocities and pressures.
That's okay though, maybe somebody else will read this thread and go "AAAAAaaaaggghhhh, that's what I can do".
Sorry you took my information that way. I don't have an ignore list.
Best wishes as you move forward.

I use 40grains of 4831 under a gas checked 200 grain lead boolit.These were cast in a Lyman mold that drops them at .311. My old 742 jamamatic.3006 shoots them less than a size of a quarter at 75 yards.I don't have a chronograph but estimate them around 1850 to 2000 fps.The old gal functions good and no signs of high pressure and the recoil is not heavy.
Read posts #5 and 12 again; that is the answer for H4895 and a starting load under a 200 gr cast bullet for the M1A in 7.62 NATO.

When using data from Lee's book, one should bear in mind that he used data for jacketed bullets to extrapolate the reduced loads from. Expect lower pressures and higher velocities than what he shows when loading with cast.

Got it. I was listening when you said that. I am going to start at 25 grs just to be well below and work it up to where it cycles the action. Once I find that spot I will load a larger amount of test ammo for accuracy and continued testing. First thing for me to find is what point the action becomes effective. Thanks for your help.
Interesting. I will know more on the second batch when I pull out the chrono.
