220-230 gr flat nose 30 cal boolit

[WCF3030]

I would like to have a mold made for a 220-230gr flat nosed bullet for my H&R 30-06.
I've been on mountain molds and have played around with a design, but I'm not sure what works. The pic is of a 230gr with a 83% metplate.
I will be useing WW and I've given thought to having a nose cavity for possibly a pure lead soft nose for hunting.
I'd like to push the round somewhere in the 1900-2050fps range.

Any help with the design would be appreciated

I am not familiar with H&R 30-06. Is that a different kind of brass or is that an H&R rifle shooting a standard 30-06 round?

Would all those exposed lube grooves pick up powder in the cartridge and cause problems? You would be lucky if the second groove from the top was covered by the case neck.

It Looks like it would be an interesting boolit to fire.

WCF3030, .30-06 can have a longer nose with bore-ride, and my experience has been that lots of meplat is not so good. I had a .32 Special 190 gr. made up by MM, and he said he had a hard time boring that flat - about 75%. Also, my RCBS 25-85-CB has a large meplat and is just not balanced in my opinion - it shoots poorly at anything over about 900 fps. Admittedly this is based on just a couple of moulds. I have often thought that Lyman 311335, which is a 220 gr. RNGC, could do with one more grease groove and a 50% meplat. Or 311284, with a 50% meplat wouldn't be bad either. The RCBS 30-180-FP is very good, but it is casting about 190 gr. out of my mould, which is a bit lighter than you are seeking.

I am no expert but I think you will need more nose and less body.

A Loverin style might suit you in a heavier weight. Similar to what you have with a long body and relatively short nose.

The Lyman 311284 and 311299 are both proven designs for .30 cal. rifles. They are both nose bore riders.

There is a group buy on right now for a 314299 clone (a slighly larger diameter 311299) on the active group buy forum. It is 200 gr. though.

I was wanting a heavier version than the standard 200 gr. but got voted down. SwedeNelson posted a drawing of a heavier version at 220 grs. which I like here:

It seems to me that SwedeNelson has posted several other drawings as well so a search may turn them up.

You might also look at C.B.E. designs here too as they have a very good reputation for accuracy so may help you decide on design:

Maybe that will guide you in your design.

I assume this is for a bolt action rifle.

If so, you will most likely encounter a feeding problem with an 83% meplat. At a minimum before I had a mold cut to those specs, I'd take another cast bullet with a long nose and cut a meplat on it with a flat file. Make up a " dummy round " and see if it will feed off the right and left rail of your mag. box and into the barrel.

Designs like you've drawn often create feed problems.

Whoops!

I missed the meplat part.

You could use the basis of one of these proven designs but modify the nose to provide the meplat you want.

WOW thanks everyone for the quick reolies.
This is for a break action single shot 30-06. The H&R are often known for generous throats.
I redesigned the bullet with a longer nose and a 77% met plate and 4 lube groves.

Next question is twist.

Minimum of 1 - 10,.........would be even better for that long puppy if it were 1 -9.

Few if any factory rifles that I know of have a twist like that in 30 -06 .

WCF3030,
A flatpointed Lyman 311284 would meet your requirement of made from w.w. alloy. They shoot fine in my .30-30's.

I have a 1.385 long 250 gr 30 cal bullet that shoots good out of a 10 twist at 1750 so I don't think twist will be a problem. It only has one lube groove plus the space over the check so I think you could lose at least one groove without causing leading with a decent lube. Since you're using a single shot if you have trouble chambering that long round seat the bullet so the bottom grease groove is in the case neck and have the gun throated so it just chambers. How long is that bullet and how wide are the grooves?

I have a 230gr boolit in 30-06, a FP at that, and it's pushing the very edge of the envelope on stabil flight at 1850fps out of my 30-06. At 100 yds I'm starting to show signs of keyholing. Oblong holes in paper if you will.

I'd drop back about 10 grains and go with that.

Here is a pic of my heavy, and the HP twin.
Basically it's a long 311284.

Jim at CBE in AU does a bullet that would go close.

CBE make a boolit thats perfect for what you want. Pat

If it's for a bolt gun I would do away with the lube groove.

I had Buckshot HP my 311284, and with ww it drops about 215, shoots like a million bucks in O6, and my Mosin. The old 284's drop a bit fatter than the new ones, and mine drops at .314. Might want to give it some thought.

I was wanting a longish heavy boolit for surplus 8x57's on the market. The above is an 8mm boolit design I dreamed up and had Lee cut into a single cavity set of blocks for a group buy several years back. Depending on alloy it will run from 236 to 240 grs. The example on the right was sized to .314" :-)

It was accurate, but a lot of lead to send downrage to punch holes in paper. For some reason I thought I needed to shoot it to 2300 fps. I don't know where that number came from, ha! I used surplus WC852(S), and shot it from a M38/46 Turkish Mauser. I did reach 2300 fps but in the process it cracked the stock through the mag relief, the rear guard screw and into the wrist.

I was glad I'd reached the goal (for whatever reason) and could stop shooting as I was feeling rather abused.

Thanks for all the good info! Gives me lots to think about. Although I can't seem to find a mold on the CBE site.
