Hi everyone. Does anybody have any cast bullet loads for a 3030 winchester. I would like to plink & hunt small game with my
rifle, but factory loads are much to big . velocities aruond 1500 to 1800 fps is what I'm looking for.

OK, here's some from Hodgdon Powder Data Manual Twenty - Fifth Edition. These are for jacketed bullets, but should work ok in cast of similar weight if that's your intent. (I wouldn't assume the same in reverse since jacketed bullets will cause more pressure than cast) As always follow standard reloading practices of working up a load for a given gun without assuming anything.
100 grain bullet H4227 min 15.0 grains 1908 fps 22,400 cup max 18.0 2077 fps 26,300 cup

My favorite reduced loads are with heavy bullets at sub sonic speeds. They are fun to plink with because the noise factor is dramatically reduced by eliminating the sonic boom but there is still some impact because of the heavy bullets.
On the subject of reduced loads, you may want to read up on detonation in P.O. Ackly's Handbook for Shooters and Reloaders. Reduced loads of slow powders have been known to detonate. I have seen even "normal" (according to the reloading manual) loads of slow powders detonate. Detonation is quite sobering and destrutive to the gun and possibly the shooter or bystanders.
For these reasons, I use only fast powders in reduced loads and I use filler. I use 1 grain or so of polyester fiberfill (like you buy at a fabric store for quilt batting or pillow stuffing) to hold the powder in the bottom of the case and magnum primers (to insure good ignition). Most of the theories on detonation involve what starts out as a squib load which then develops explosive gasses then detonates rather than burning at a high rate.
With that said, my favorite light loads for a 30-30 would involve the heavier bullets and the faster powders reducing them 1/10 of a grain until the "boom" dissapears (or a chrono says they are around 900 fps).
I'm fond of Red Dot, Unique, Bullseye and HP38 for fast powders for reduced rifle loads. I'm sure others work fine too, but I've had good luck with these.
The Lyman Cast Bullet Handbook Third Edition lists 173 gr #311407 bullet from #2 alloy with 7 grains of Unique going 1203 fps. It lists 170 gr #31141 bullet with 6.5 grains of Red Dot going 1159. 7.0 grains of Unique going 1240. If you start with the 6.5 grains of Red Dot and 1 grain of fiberfill to hold the charge in the bottom of the case and back up 1/10 grain at a time you should be able to get to a subsonic load.
Of course there is always the possiblilty of a squib fire. In other words the powder doesn't adequately ignite and the bullet gets lodged in the barrel. Always make sure the barrel is clear when working up a reduced load.
And there is the issue of detonation to be taken into account when doing reduced loads.
