Hello, I have recently started casting some of my own bullets as a natural outgrowth of reloading. (OK I'm late to the dance 'cause it's getting hard to get free or even cheap wheel wts) Any way... I have cast and am ready to load some 150gr, .309, gas checked, 30-30s. I have RCBS Cast Bullet Manual #1 and they list 10-12 gr of Unique or 27-29 gr IMR 4895. I would like some of you more experienced reloaders to advise. I have either powder and may end up trying both I just want to see if anyone has already evaluated these. This is for a Winchester '94 made in mid 70s. I really would like to get this set up and ready for deer season this year.

Do you plan to hunt?

Or is this for range work only?

The best 150 yard hunting load for me is a cast gas checked bullet going 1,700 to 1,800 fps. As a rule, the slower burning powder will give best results. Save the Unique/Red Dot/Bullseye for 1,200 fps target or plinking loads.

I am not familiar with the RCBS cast bullet manual but have a Lyman Cast manual that is my constant reference.

Be careful, this site could subsume your soul. LOL

^^^^ I agree 100% with above. When I first started loading cast bullets in my 30-06 I was using fast powder like 700x. Terrible results. When I switched to 4198 it was amazing, went from 12" to 1/2" groups at 50 yards.

70s winny '94 same for me. GREAT gun for cast. found mine did a bit better going to .310 with/GC. without a GC stick to <1,500 fps. mine also liked the 170/173 GC combo better and I doubt you will be able to develop a better hunting load anywhere else for this rifle.
I know your stated goal is hunting but for a real hoot and some plinking rounds try 6-7 grs of unique under those boolits. everyone around you may start screaming that you just fired a squib but you'll be laughing like **** with some good results.

IMR 4895-27.5gr -173 gr GC-1500fps is what i cast/loaded in 30-30 Velocity was out of a 10" barrel T/C. I didnt check it in the M94. Would be higher, i guess.

I re-size all my 170/70% Linotype bullets to .310 GC, I use a hard lube (Blue Magic?) and 24.0 grains of 2230C with a WW primer RP cases, I resize the cases to 2.032, with an OAL 2.452. I've found these to be very accurate in my ballard rifled Marlin. MOA at 100 yards.

I've gone to a .311" sizing for all my .30cal uses.
For the .30/30, which is probably the best cast-bullet cartridge of all times; I prefer the very first bullet I ever cast. The Lee .309 FNGC. It casts to about .312". I size and lube them with either SPG or 50/50 Alox=Bees Wax lube.
The .311" works with every .30cal rifle I have and gives best accuracy from a Marlin Micro-Groove barrel. Keeps from having so many different sizes.

Most any typical powder for the .30/30 will work fine. I happen to use RL15 in many other applications, so I use it here too.
30.0gr will deliver about 2,200fps and superlative accuracy.
28.0gr of H4895 or IMR3031 also works really well.

Do be sure to adequately flare the neck. I also use a Lee factory crimp die to crimp the brass.
Do sort brass by headstamp, trim to minimum specs, and use a Federal or Winchester Large rifle primer.

The Lee 170gr FNGC also works well. For a lighter than typical bullet, the Lee 120gr RNGC also works well. Loaded over 10.0gr of Unique, it's a plinking delight...
