View Full Version : Can I load 200+ gr. boolits in 30-06/308 with H4895?

I'm aware that most loads for cast boolits in 30-cal recommend faster powders than H4895, and that heavier projectiles may complicate the use of slower powders. That said, several members have mentioned H4895 loads for 170-180gr. boolits; does anyone have experience with this powder in heavier loadings for 200-yd hunting?

While I have not yet loaded the real heavies(200+) in my .30 cal rifles, I load the 180 grain lee flat nose with 33 grains of H-4895. I would not hesitate to go to 35 or so with that powder, your rifle and chronograph will tell you when you are getting what you need. I use 33gr as I got the accuracy I need at that wieght and velocity is ample with the soft boolits I am using. I have also loaded the 8mm Mauser with a 237 grain cast boolit and 33 grains (go figure!) of H 4895. I did expereince delayed ignition with those loads until I started using a filler to hold the powder against the flash hole. Then everything got a lot better. BTW, I use puf lon filler and those are my 2 hunting loads for deer with cast boolits.

The simple answer is yes 4895 is a highly recommended powder for use with 160 + gr cast bullets (that includes 200+ gr cast) in the 30-06. I suggest a starting load of 26 gr with a 1/2 - 3/4 gr dacron filler. Work up to 32 gr.


"and that heavier projectiles may complicate the use of slower powders."

That is actually backwards. Heavier cast bullets for caliber actually uncomplicate the use of slower powders because the heavier cast increase the psi of slower powders into the range where they ignite/burn efficiently while keeping the velocity down for accuracy. Many slow powder such as AA4350, RL19, H4831SC and RL22 plus several surplus powders work very well.

Thanks for the resource, and thanks LG for explaining the ballistic mechanics I was missing. Once you mention it, I recall that the reasoning behind faster powders was due to the lower friction/lower operating pressure of cast boolits versus jacketed; the corollary is that heavier boolits should like slower powder again...!

At those low loads, I can see the need for the filler, what's your favorite source for Dacron, etc.?

Walmart or any good craft supply store should have it.

As long as you're shooting a 1/10 twist or faster H4895 should be ok. I've always liked it for the 223.

Dacron is a trade name and what is special about it is that it has fine fibers. That is better than cause fiber polyester. Old pillows are a great source (so are new ones!)

I prefer slower powders for safety sake - thinking or potential double charges. I want a double charge to overflow the case. If one insists on a faster powder for lighter loads then choose a powder and load that is still safe at double load levels.

I use H4350 for paper patched but was worried about low load densities and poor ignition (never mind SEE's).
Jim's post is very reassuring - thanks Jim. :drinks:

Lowest pressure, highest velocity and largest charge. What's not to like?

I shoot the Accurate molds GC version of the 245/247 boolit in my 30-06 with 35gr of H4895 @1,950fps. Shoots very well in my Savage Edge.

I keep getting the impression the 30-06 is an excellent cast boolit cartridge!

The sticky "filler" will give you lots of useful info, including where to get dacron.

I think it was Col. Townsend Whelen that said "The .30-06 is never a mistake."

Sounds like it's time to shop the craft aisle! Maybe the cereal aisle after that... I like the idea that I can use the same "slower" powders for cast that I previously used for jacketed loading, and they have a measure of safety built in.

Ever thought about using Kapok? I wrote an article on it, it's in Castpics.

Kapok Jim???

Where can I find a life preservers old enough to have Kapok?

Actually I have one I have kept around for years in case I decide to start using fiber filler.

Famdoc;

I have been shooting the RCBS 30-180-SP - HT from the mold, weighing 190 in my alloy - in my 30'06 all of this past summer. It shoots around 2000 ft/sec out of my 26 inch barrel over 32.5 grains IMR 4895, no fillers or tricks. Accuracy is very good - not extremely good you see but very good. ~ Hunting accuracy is a lead-pipe cinch.

I shoot this combination over our 10-target long-range silhouette course out to 834 yards. The load is capable of holding in-the-white accuracy all the way out there - provided I do my part .. and conditions aren't too radical.

However, a HT solid point bullet isn't really all that wonderful for hunting. You might be able to talk with me about my Ideal U311299HP though.

Good evening,
Forrest

I have an 1980`s Futon I discovered has 1000 years of Kapok inside.

Famdoc;

Here are a couple shots of my old load book data sheets showing the performance of the Ideal U311299 with 24 grains 4198 in the M1903 Springfield.

The information is there, I hope everyone can read it well enough to be interesting.

Good morning,

Gentlemen;

I have read that the data portions of those two pictures are not visible.

I don't know much about these computers but this one allows a fellow to choose "magnifier" (useful for old guys like me) and point the machine to the text/information that is of interest to them. ~ At 200% the text is legible.

The data is there for your consideration and one of the attachments has three filled licenses glued to it.

Good evening,
Forrest
