I am a reloader of minimal experience. I am reloading for a .30-30 Win Model 94 and I prefer lead bullets. There is a lot of data on 170gr Jacketed but very little on 173gr FNGC. Is it safe to use loads for 170gr Jacketed for the 173gr Lead? I have no wish of using Max Loads. I primarily use the Lee Dippers but I do have a scale and dispenser. Currently I have H4895 and Accurate 2520. Using 1.6cc of 2520 does not seen to be enough. I am worried 1.9 would be too much. I have the Lee Manual and the .30-30 load booklet. Thanks, Keith

I would use the data for jacketed and work up, yes. Suggest that for this exercise, forget the dippers at least at first. Need to workup in finer increments.

Also, would suggest getting a Lee Factory Crimp die. It helps with cast bullet loads, as does the Lyman "M" type of expander.

Seat bullets so that they lightly engrave the rifling when the lever is closed. This helps a great deal with cast bullets. Good luck.....

Thanks Mike, I am just taking it slow and cautious. I do have the Lee Fact Crimp. I was just noticing it seems lead bullets use lighter loads of powder than jacketed for the same or similar weight. I don't know if it because of possible leading issues or lead increases presure. It would seem to me copper jacket would result in higher pressure.

With a gas check and a hard lead bullet, you may need more powder to get the same velocities. The lead bullets engrave into the rifling much easier and this can lower pressures a bit. The FCD and seating the bullets to engage the rifling helps the powder burn more uniformly.

Good to be cautious though.

Probably won't have a dangerous load with 4895 even with the 1.6Cc dipper (which would be about 22-23gr. (depending on how you scoop) of H4895. A 1.9cc dipper should give about 26 grains. Haven't used AA2420, so can't comment on that powder.

I'd defiantely start with some loads using the 1.6gr. dipper. Might only see 1500-1700fps, but usually that's a sweet spot of lead bullets.

NO..can't fully equate jacketed loads with lead loads. Lead thends to be more like putty at higher pressures, and odd things do happen to pressure when a lead bullet deforms from the kick in the arse of high pressure. At lower charge weights, often get MORE vel. than a jacketed bullet (less friction) but at higher charge weights, often get more pressure than with jacketed loads (bullet deforms and actually offers more friction).

Thanks All! I will use my powder measure and scales to develop load. I may make my own custom dippers for a load or two I like. I read a article on BTB about making dippers. Grand Ma had it pretty easy with the popsicle stick for the snuff. I appreciate the info you all have shared.
