Bullets made for the 30-30 and similar cartridges will have a fragile jacket that will open up at the slower velocities produced by the 30-30. The 308 if loaded to normal pressures for the 308 will push that bullet 5-600 ft/sec faster. Will likely result in the bullet mushrooming rapidly and resulting in excessive meat damage. If you just want a round nose bullet just about every bullet maker makes a 180 gr RN that would be better suited to 308 velocity. Speer also makes a 165 gr RN that would be good as well
 
If you’re going to load lighter Bullets in .308 for hunting rokoro Is right. You’ll want to match the velocities of the 3030 equivalent load for proper bullet expansion. In .308 4895 is an excellent powder for this. It can be safely downloaded below published minimums.

Hogdob released a notification on doing it. It’s commonly used by lead bullet casters.
 
If you use a slightly lower velocity window the 170 grain RN Nosler Partition bullet designed for the 30-30 there is reports of this performing well in the 300 Savage, 307 and 30-40. With a slightly lighter handload in the 308 you should be able to duplicate this as long as cannelure position does not pose a problem.
 
Thank you Rokoro

You have confirmed what I thought about the make-up of the 30-30 bullets etc .. being too fragile for .308 velocities. I had some of these left-over from when I reloaded for my dirty-thirty. I may end up selling them.
Thank you.
 
Thanks MuthaFunk

I have heard that H4895 is a very good universal powder ... tough to find these days. I was using IMR 3031, and IMR 4064 in the .308. I picked up some RL-15 to try.
I have have to either sell these .30-30 bullets if I cant' find a decent powder/reduced load.

I ordered a Lyman reloading manual ... I will see if there's anything in there that offers a reduced velocity load.

Thank you
 
Thanks Brutus

Good to know. I got a Lyman manual coming in the mail ... I will be reading up on some options. I had not thought about the .307 ... I will have to see what load offerings are listed for it and see if there's something close.
Thanks
 
Went through some manuals here - that 170 grain Sierra - looks like B.C. is about .248, if between 1,800 and 2,400 fps (Sierra) And Sierra seems to show max for that bullet in 30/30 about 2,150 at the muzzle. Seems, based on 165 and 168 grain loading for 308 Win, probably can safely get 2,700 for that bullet from 308 Win. With that B.C. at 2,700 fps muzzle, will be 2,349 fps at 100 yards; 2,036 fps at 200 yards. (Nosler table) So, whatever results that you get with that bullet from 30/30 (max loading), will get same results about 150 to 175 yards further out with the 308 Win (max loading). Same speed, same point of impact, should perform the same, just 150 to 175 yards further away. So many better choices for 308 Win for 200-300 yard shots - except, if you have them already, no cost!

NP friend. I to believe this specific Nosler bullet/load was promoted as a reliable black bear load or closer range elk harvester.

Good luck.

Hi Potashminer

Thank you for digging and looking into this ... I’ve got a Lyman manual on the way ... I’m going to look into this further for sure.
You’re right ... there are better options... and I might put these up for sale/trade.
It’s a brand new box of 100.

In my head ... I was thinking that they should work ... but I’m beginning to wonder.

Thanks for weighing in.

I have loaded 170gr flat nose .30-30 bullets in .300 Savage. Very effective on caribou.

Hi Tiriaq

Ok ... good to know. And the 300 savage would be faster than the 30/30 correct?
I’m not up on all the specs.
So .... potentially there could be a slow enough load for these bullets with the .308.

I’ll be reading once my Lyman manual arrives.

Thank you
 
OP - from Lyman #49 manual - they show 170 grain CAST bullets (not jacketed) to 2,456 fps in Tiriaq's 300 Savage. Those cast bullet data are probably not useful for jacket bullets!!! They do not list mbogo3's .303 Savage at all. Went back to Speer #5 Manual (1961) - they do not list .303 Savage either.

Hi Potashminer

Ok. Thank you for checking those calibers ... agreed ... I’d need to find a recipe for jacketed pills, if it exists.
This quest could be a lost cause. I’ve heard that H4895 and IMR4064 can be loaded fairly low ... Sierra (online data) showed that 38 grains of IMR 4064 produced 2300 fps for their 168 gr Matchking round.

Another person PM’d me and said that 40 grains of H4895 were called for when using 170 gr SP. He didn’t specify what bullet our make ...

Problem is, I don’t have either of those powders! Lol. I tried to get order some H4895 from Wolverine gun and tackle (a tip from a fellow CGN), but there was no shipping option ... in store only (Alberta) and the price was $63 per bottle.
I might try and get some IMR 4064.

I’m sure I’ll have some spare time on my hands if Ontario brings more lockdown protocols.

Thanks so much.


My Lyman manual is supposed to come tomorrow.
 
I have loaded .30-30 170gr bullets in .303 Savage. Work fine. Cannelure groove was in the wrong spot, but that didn't matter.
Don't know what make of flat nosed 170s I had. Bulk purchase, very modest ogive, prominent flat point. Might have been surplus Gevelot bullets.
I suspect most any lower end load for 180gr bullet in .308 would be just fine with these 170gr. .30-30 bullets. They might impact quite violently with top .308 loads, but that could be speculation. I don't know that I would lose much sleep worrying about it.
 
From the Lee 2nd edition 170gr in the .303 Savage.............Lever Evolution 29gr/1913fps........MAX 33gr/2145fps. IMR 3031 24.2gr/1747fps...........MAX 27.5gr/1959fps. IMR 4895 26.2gr/1728fps............MAX29.8gr/1938fps
IMR 4320 26.4gr/1762fps..........MAX 30gr/1976fps. Varget 26gr/1762fps.........MAX 29.5gr/1976fps. IMR 4064 26.2gr/1775fps........MAX 29.8gr/1991fps. H4895 24.2gr/1737fps.........MAX 27.5gr/1947fps [OAL 2.550"]
 
Sierra lists their 170 FN as suitable for velocities up to 2500 fps. I believe it's on their website.

I think I have some Remington 180 pointed core lokts kicking around here if you're interested in doing a straight trade.

Hi Tiriaq
Great input - thank you.
Agreed ... I will be looking into the lower velocity ranges.
