200 gr ww in Springfield 30-06 w7828

[eldorablerentals]

Hi
I asking for load data advice and trying to work up a load for a Remington 7400 chambered for for a 30-06 Springfield round.

I have a 309 lee bullet weighing in at 200gr cast from wheel weights and I am wishing to use 7828 powder. Because I have it.

I am curious about preferred powders though.

I can either go with a gas check or not...
Advice?

Thanks Jerry

7828 powder is at the slow end and probably be to slow for cast. I use IMR SR 4759 with 210 cast GC in 30-06. If your cast boolit is made for a GC I would use them.

A Lyman manual will list several loads suitable for cast in 30-06.

definately a gas check.
and don't jam the boolit into the rifling.
you most likely won't see any leading other than the grey smoke at the bbl.
and you'll want a pretty close target to start with.
the recoil can be stout.
i'd make just a few to start with.

7828 too slow. I'd use 3031 or RL-7 or 5744 start at the "starting load" level for jaxted boolits and work up in small increments.

According my chart, 7828 is slower than H4831 and faster than H870. I have used both of those in my M1. There is a lot of information on using slow powders in the surplus powders thread. Right now I'm loading wc860 and wc872 using 43 grains over a 3grs of 3031 kicker, a mag primer and 1 gr. of dacron. The dacron filler keeps the load from moving around so that kicker doesn't migrate. This load is running about 1700 fps, burns clean, cycles the M1 action, and has mild recoil.

I was finding loads on the IMR website for 200 nos ab bullets, but nothing for a lee 200 grain cast bullet. I am new at this, so I'll ask. . . doesn't the slow powder reduce the kick but give a heavy bullet like this a better velocity?

I have the 7828 already and will need to use it somewhere... The 30-06 is the largest thing I have... except for an old trapdoor. Didn't even think about going there.

[runfiverun]

some of them do.
the 7828 is one that looks right on paper but is in fact not good for cast.
a heavier boolit is to make up for the lower velocity.
powders like unique, and 2400 through 4895 are more suitable powders for the velocities we normally use.
1600 through 1900 fps are very stable and accurate velocities.
cast is not a direct substitute for jaxketed bullets in velocty, they can do a lot of things very well and most of them easily, but going fast takes a lot more work.
enjoy the lower recoil,and lower powder costs and often the higher accuracy for what they are and don't make them what they are not.

I should have mentioned that I'm using the Lee 200 gr. bullet with those 860 loads. The problem with a self loader is that in order to get enough pressure to work the action, using faster powders, the velocity gets high enough to affect the accuracy. Slow powders, heavy bullets, WITH CAST BULLETS, not jacketed, work very well.

H4895 is a great powder for autoloaders like this (the 4895's were designed for the gas system in M1's). My son has a 742 in 30-06 and H4895 is our go to powder for it. Too slow a powder may not produce the pressure required to cycle the action.

[hydraulic]

Moonie: What cast bullet are you using with 4895?

[Moonie]

170 Lee

[hydraulic]

Moonie: I'm going to go give that another try. 4895 is my favorite powder, but my starting load for the M1 was 45 grs. 4895 with the Lyman 31141, which is a 170 gr. bullet, and it just slung bullets all over the landscape. Anything below 45 grs. wouldn't cycle the action.

[Moonie]

Interesting, 35gr of H4895 and that 170gr lee cycles my sons 742 perfectly, every time.

[hydraulic]

Must be the difference in rifles.

I have no problem using 30.0 gr 4895 and NOE 311299 cycling Garands. But my Garands are also lubed properly, use USGI spec oprod springs, and an in-spec gas system. Worn gas systems allows excessive blow-by.

A worn gas system could be the problem. My M1 is a rack grade I bought from the CMP in 2007. I've never done anything with it except grease it and clean it regularly and shoot the heck out of it with slow powders and heavy cast bullets. Just like all the other rifles on Cast Boolits, it puts all the bullets through the same hole.
