Author Topic: Jacketed load data for lead bullets (Read 666 times)

West Creek Charlie · « **on:** July 06, 2004, 04:39:30 AM »

I have an old Marlin chambered in 32-40. Load data for it is very slim and hard to find. I have some load data from an older Lyman book but the only bullet listed is for a 170 grain jacketed. I have loaded some 4227 and 4895 with good results at the 1400 fps range as far as accuracy goes.

4227 is listed between 14 and 16 grains and I find that my velocity is within 100 fps of that listed load with a lead 170 grain bullet.

4895 is giving me 1400 fps with 15.3 grains and also shoots pretty good.

These loads will most likely be most of my shooting but I would also like to develope a hunting load for it with a velocity of 1600-1800 fps. These old marlins were chambered in 30-30 so I guess my thinking is that the gun should handle 30-30 pressure without any problems even though the 32-40 sammi pressure is lower

Since the load data for the 32-40 is very scarce and I have very little experience loading rifle loads and powders I am leaning on the side of caution and approaching this project with caution.

The lyman manual lists 170 grain jacketed loaded with 4198 as having a velocity upwards of 1800 fps and a charge of 33 grains. Thought I would give this powder a try. I think they also list 4895 with alot more powder than I am using with velocities in the 1600 fps range.

I guess my question here is Can I use this jacketed load data with a 165 grain LBT LFN flat base bullet lubed with felix lube.

The problem I see is if you load too hot a load with lead bullets, you will lead your barrel. I would try to see if you can get someone to cast you some bullets with gas checks.

Also try here, it is load data for the 32-40: http://www.hodgdon.com/data/rifle/3240win.php

West Creek Charlie,

I have lyman loading books that go back to 1936. After reading your post I checked from 1936 to 1953 and didn't go any farther. I would be glad to send you what I have in the 32-40. The only jacketed bullet they list is the 165. The rest are cast plain base and gas check. Please get some more information before you handload. The max powder for the 4198 you spoke of is 21.5 so the 33grs you spoke of is to hot. If you need the information that I have in the old lyman reloading books just let me know and I will send them to you. Carl L.

I have used jacketted data for lead bullets before. The velocity you get will be higher than the velocity listed for jacketted. Lead bullets have less bore friction. Thats why you may see some leading. Be sure to start with minimum loads.

Thanks Carl

I was going from memory there with those numbers and could be wrong. It might have been 4198 that had the higher charges. I do know however that the 4895 charge I am using is below minimum and the velocities I am getting are higher than the jacketed data for sure.

I have an LBT mold for this rifle in 165 grain weight with three grease grooves so I am hoping leading wont be a problem. Only trial and error will tell. If leading is a problem I can get another mold with a gas check.

Anyway - I would greatly appreciate the load information you have on the 32-40, specifically the lead bullet data. The only current data I can find is hodgens and it doesnt apply to 165-170 grain bullets.

Email me at blink@netnitco.net for any details you need etc.

Thanks a Bunch

This may be a good question for Veral of the "Ask Veral" forum. He does cast bullets for a living.

West Creek Charlie,

I sent information from 3 lyman manuels to your e-mail. I ran them off of the scanner. Let me know if you don't get them ok and I will try again. Lots of luck with the 32-40. Carl L.
