Lyman #49 lists .308 with a 160 cast with all three of those powders.

Oh O.K.
But you really need to buy a Lyman #49 if you load cast bullets!

2400 - 15.5 - 19.5.
RX-7 - 25.0 - 34.7.
IMR-3031 - 28.0 - 38.0.

"Reasonable poa/poi at 100 yards"? You're going to get what you get.. there's no "reasoning" with what the load will do. adjust your sights if/as necessary

I use 2400 in my FR-8 with a 180 cast RN, 20.0 grs., and a 173 gr. cast RNHP, 22.0 grs.
The velocity of the first load is 1750-ish fps. The second load runs a little over 1850 fps. The second load has been used quite a bit in my family for deer. My oldest daughter and I have together killed probably 6 or 8 deer with this load/. Below is a group (left target) I fired with the hollowpoint load several years ago.



In my FR-8 when I sight my jacketed load (150 gr. Remington SPCL @ 2700 fps) 2.5" high @ 100. the hollowpoint load hits just about dead-on @ 100, maybe a tad above point of aim.

I built my wife a Scout rifle based on a Mauser 1916 and use identical loads at very similar velocities but points of impact are WAY different for what ever reason.

Good luck,

yea 20 gr of 2400 is a super load in my 308.
I have also used RL-7 with good results. I quit using RL-7 in my 308 though. Has become to Valuable for my 300 Black out cast loads.

Oh if you have some and get a chance. Load up a few ahead of 13 gr of Red Dot. You maybe surprised how well they shoot.

For a cast bullet book, Get the Lyman's new cast bullet hand book. They have quite a few loads that Lyman's 49th does not have.

Using pistol powder in rifle cartridges will probably need a fluff of kapok or dacron whatever passes for that today. You put your powder in the case, make sure it is at the bottom and put the dacron over it pushing it in with a pencil or nail or whatever. THEN seat the bullet. Otherwise you'll have some trouble with the loads and could even get some dangerous pressures.

It has been found long ago that red-dot is particularly position insensitive with approved loads. There are many more that are flat position insensitive. no filler "required"/advised
