I am looking for a plinking load for an Ishapore Enfield 7.62, I have a qty of 150gr fn cast from Lee mold. I also have about a pound of Unique.

C.E. Harris proposed two "universal" .30cal. loads (includes metric .30's). One was 13gr. Red Dot, the other was 16gr. 2400 with cast bullets. Since Unique's burning rate is somewhere between these, start at 13gr. and work up to 15gr. and watch for pressure signs. I.e., while pistol powders (fast burning rate) work well in large rifle cartridges, e.g., the 7.62 x 51mm, small increases in the charge can result in sudden pressure rises. If you have a chronograph, by all means use it since you can immediately see what effect a 0.5gr. increase (or decrease) in the powder charge will have. Also, once you use up the Unique, consider trying some of the much less expensive military surplus powders, e.g., WC 860 (very slow) or WC 820 (much faster, but with a burning rate ~Accurate Arms' #9). If you go this route, you can search the board for loading data or go to the Castpics site.

Hope this helps!

Try 14 or 15 gr of Unique and your lee boolet.

I'm using 16 gr of 2400 to power a 155 Lee boolit. That's a similar load.

Accuracy is very good at a hundred yards. I have not tried it farther.

This load is very pleasant to shoot. I've tried it in two 1903 A3's and an M1 Garand. It did not cycle the Garand's action, but that's OK. I don't like cleaning sand off the cases.

Try 8.0 grs. of Unique and see if you can seat the bullet into the rifling at least a little. I neck-size brass previously fired in the rifle with a .310" expander ball and then use a .311" RCBS tapered expander to flare the case mouths and expand the necks for .310" bullets. With the Hirtenberger cases I'm using, there's enough neck tension to allow me to start the bullets by hand and complete the seating in the press. I load the bullets long so that chambering the round forces the bullet deeper into the case. With the lack of camming force in the Enfield action, this may not be possible for you. I also reamed out the flash holes with a #40 drill to try to prevent the primers from backing out. So far, this has worked. I have been using pistol primers, but am going to try rifle primers this weekend if the weather cooperates. Accuracy on calm days is in the 2" - 3" range at 100 yards with a scoped rifle. Not benchrest, but pretty good for $0.02 bullets. I don't know for certain what sight setting you'd need for 100 yards, but 600 yards might be the place to start.

On my A2 I use 10.0gr to 11.0gr Unique, 180gr,309 Lee bullet. Use the 1.3cc Lee diper.
I've found that 10.0gr,11.0gr,12.0gr all shoot about the same. Over 12.0gr the primer starts to get flat. But it seems to still be safe.
Very soft recoil, easy on shells, cheap to shoot. At 100yds, standing, I can hit a 7" metal plate with ease.
You might also try 13.0gr to 14.0gr of Blue dot. It seems to be a little more accurate with less felt recoil. Burns much cleaner too.
Unique has become my cast bullet powder by default. I got #10 from an estate sale. Use 10.0gr to 12.0gr in almost everything from 6.5 to 45-70 with great results. Turned out to be a real money saver.
