ok guys....thanks....
would you consider this 16gr a starting (min.) or the maximum???

I have an older lyman manual which gives the minimum for a 210 gr boolit and 2400 as 15gr and the maximum as 23gr.....I thought the 23 grains was a bit on the high side
thanks again

[Ben]

I've shot 17.5 with a 210 gr. before in the 308 Win. with no problems..........23 grains, NO....not in my rifles.

If I'm looking for more velocity than the 17.5 gr. load can generate, I'd switch to IMR 4198 or IMR 4895 , both fine powders that are capable of excellent accuracy in the .308 Win. with the correct 200 - 210 gr. cast bullet ( and I might also add doing so with much milder pressures than a load of 23 grs. of 2400 would generate ! )

Years ago Lyman did a lot of testing with rifle cartridges and relatively fast burning pistol powders, MANY of the loads they have listed in reloading manuals for cast bullet shooters are basically useless and will not deliver even mediocre accuracy.

For whatever their reasons they often times ignored and failed to provide much, if any, data with the " medium burn rate powders like IMR 4198 and IMR 4895, SR - 4759 " which have so often provided the very best accuracy for me in cartridges like the 308 Win.

Makes you really wonder if they shot any of those loads on paper or if their data came from test barrels in a test facility with no effort to " put them on paper ". I've tried to put them on paper and the only people that benefited from my efforts were the powder and primer companies.

Ben,,,I tend to think they did NOT punch any paper...buy the way your targets show some very good shooting !

I have decided that 2400 is probably not what I am going to use for this 210 gr.....I think I will try IMR4895....OR,

Have you ever tried Win 748 with a 210 boolit? I have found this a very accurate powder/ load combination with my 180 gr RN but I don't have a load using this powder with the 210 grain.

thanks again

atr :

IMR - 4895 is a SUPER cast bullet friendly powder in the .308 Win.

Win. 748 is a fantastically accurate powder in full power loads in the .308 Win with jacketed bullets. However, being a ball powder, it will begin to show combustion and ignition problems if you reduce the charge weight down into a " cast bullet friendly zone " . A lot of empty air space and low internal case pressures don't work well at all with a variety of ball powders in large cases.( reducing H-110 which is a ball powder causes the very thing that I've described ) I'm not the only cast bullet shooter that will shy away from using low charge weights of ball powder with cast bullets in cartridges like the 06' and the .308 Win.

Someone else my have differing opinions on this, but this has been my experience with using ball powder in reduced loads in large capacity cases.

Best to you,

Ben

[atr]

Ben,,,,good point about the air space and ignition in reduced charges with ball type powder

I am using 34 grains of Win 748 which fills the case almost 75% with the 180 gr round nose
I dont have alot of empty air space with this loading and I have never had an ignition problem. This is a good load for me (hunting), and it is accurate out to 150 yds

[Ben]

You have most likely crossed the " danger point " with your 34 gr. charge and are creating enough pressure to offer a good burn of the powder.

If it works well for you, stay with it.

Best,

Ben

[atr]

Ben,,
I am a believer!!! IMR 4895 gives me much better groups

[atr]

green background is 210gr with 30 gr/IMR 4895
other is 180gr with same load

sorry,,but the attached pictures are not loading?.....anyone know the secret?

[Ben]

atr :

Good Shooting ! !

Glad you finally managed to get your photos uploaded.

IMR - 4895 may not be " THE " ultimate powder for an accurate cast bullet load in a .30 cal. cartridge like the .308 WIn. or the 30 / 06, but it is a good powder to start with when you begin the " accuracy search " with a new rifle and a new .30 cal. cast bullet design. It has always been a proven performer for me!

75 yards
using 30gr of IMR 4895
sized as cast 0.3095
pan lubricated
#311291 lyman 180 gr as cast RN
neck sized only
expanded with 0.309 just enough to allow gas check to pass easily
negligable crimp....just enough to remove slight lip from expansion die

this is fun load to shoot, and it holds its accuracy...at 100 yards I bust shotgun clays with a 100% success rate.

[Ben]

ATR:

Looks like you've found a " sweet spot " with your .308 Win. Nice shooting ! ! Stay with it !

BEN where did you find the mold that will cast a pointed bullet! I need one

[miestro_jerry]

I have experience in shooting a 210 grain bullets in a 308, both jacketed and factory. Some of the books don't haver loads for this weight, for CBs, I use 2400 powder, IMR 4895 or Rx7

Not quite 308 but close enough to be of interest to you - 303 Brit, 220gr g/c boolits, surface lubed (smooth sides), 35.5grs Varget (AR2208). Well above the 'reduced charge of slow powder' threshold. I did not pursue this load as I went to paper patching but initial results were very promising. (Remembering that a 303 Brit seats a boolit of that weight to the base of the neck).

Ummm.... Ben, I can only see one hole here - you said five shots!:mrgreen:

BEN where did you find the mold that will cast a pointed bullet! I need one

That pointed bullet ( The Lee group buy 210 gr. HCB ) that you say you'd like is unfortunately not available anymore.

Back around 2006, a fellow named Aladdin ran a group buy. He took a lot of flack from shooters for being bold enough to design and promote a spire pt. .30 cal. cast bullet like you see. Many said it would be a dismal flop. Not so .......It is one of the most accurate .30 cal. cast bullet molds that I own.

It might be possible that you could find a used one, but there were not very many molds made.

If someone has one that they would like to sell, maybe they will PM you after reading this ? ?

The Lyman 311413 is easier to find, but will not weigh 210 grs., more like 168 - 169 grs. from my 413' molds with ACWW's.

Best,

Ben

Maybe I need to go back to remedial math class ?

[atr]

my lyman 311413 also casts at 170 gr....but I have never been able to get that spitzer design to shoot accurately in my .308 Savage.....

[303Guy]

So Aladdin designed a sptzer boolit that actually worked. I wonder what it is about it that makes it work? It wouldn't work in my rifles throat but I can see it suiting a 308 throat just fine. Perfectly, in fact.

[kjg]

hey guys i must be doing something right or wrong but my 311413 casts wheel weights at 204 grains then i size and check them and lube they weigh right at 205, i havent found anything that seems to work out of any 30 cal, except chicom sks, that thing likes the bullets unsized ay 3145, and gas checked, and 4198 one accurate load, today my 311299's shot well with 2400, from nagants, isreali .308 and beloved 303 brit im going to try that 311413 sized to 310 next wiierd, oh well evrything points to the proper sizing .

[geraldsd]

Lyman 311291 in my 308 with 20 gr of either 4198 or Re 7 performed very well.

Ben
What is the rifling of the barrel??
I think , for an 1-12 rifling is 210 grs to much.
1-10 will go better. In my 30-06.

[Ben]

My 308 that shot the group below is a 1-12 " twist rifle.

[frnkeore]

I shoot bullets that weight 210 and are 1.165 long out of my Douglas 14 twist barrel. And do it at 1450 fps. The 12 twist is all you need for any cast bullet that I know of.

[Ben]

Frank,

I never experienced any " tipping " or any other stability problems with my 1-12, 308 Win. bench rifle .
Like you say, it will shoot anything that I can cast .

I wonder what it is about it that makes it work?

If you look close at it, it has a lot of bearing surface in contact with the bore. More than a lot of spitzer designs. I think this makes the difference.
