why not just copy the 125 nosler bt with the pc coating thickness factored in. Why reinvent the wheel when theres a number of jacketed bullets that run perfectly in the bo. HPs im not much interested in. cast soft enough to expand my guess is most of them will be damaged feeding from the mag into the chamber. If I want hunting bullets ill buy a box of jacketed. what I want is a cast plinking bullet that feeds a 100 percent and hits @ the same point of aim as my hunting bullets do.
That would be good for another thread.
I would like an all around HP bullet that could be used for plinking, hunting, sef-defense, whatever. The 300 BO subsonic group buy that MP just ran could be also be called reinventing the wheel. I would disagree. Let's keep this thread on topic.
The 125 Nosler might be a good place to start from. It seems that the nose has to be .305" or less, coated, past the driving band to work. Would like a dedicated 300 BO crimp groove, but the without the boat tail looks good. Add gas check and lose the tip.

RCBS 7.62mm-130-SP. I just measured one coated with Smoke's Carolina blue - .305 just forward of the front drive band.

It is too good of an idea to let it just die on the vine.....
A successful BO mold would come with HP pins and blank pins for solids,
or as an aluminum solid, so that should really be a non-issue.
I would go for two molds without hesitation....
Please keep the idea alive....

Hello Guys
If you could pin down a specific bullet and message me dimensions I would draw up your idea and see if we could breathe some life in this buy.
Thanks

WaSalmonslayer you have the Con!!!
I am pretty new to the design thing, but not new to playing with bullet shape for application. I need a 300blk mold too, and I really like the idea of no crimp grooves. Get a design that runs pc'd and id be in for a 4 cav in whatever mold material. I don't need hollowpoint.
Here is something to chew on.
Do you want crimp or no crimp and do the dimensions look close to your needs??

Anything outside the case has to be smaller than .305" for PC and Hi Tek
If you read the thread it will make sense
Otherwise looks good
I would like a crimp groove
Would also like a no lube groove option
Thanks
I will make some adjustments tonight to the drawings.
So .305 in front of driving band with crimp
On the hi tek do you want gas check or plain base.
Reason I ask is if we go gas check regular lube groove for main design only hi tek option would be plain base.
If we do hi tek gas check design only other option would be hi tek plain base with no option of lube groove.
It would require two cutting cherries and that would mean two separate buys.
This has been the problem from the beginning of this thread
If you start at .305 and add PC or even HiTek it will not chamber
You cannot size the nose so for me the mold would be a no go
Others may be interested
Why not have a single design around .300 that would allow the application of PC or not ????
This is from post #2 in this thread
"I shoot a 300 bo AR and have several friends with them as well. So far only about half of them will handle a bullet that is north of .305 in front of the driving band. Throw in PC and it gets even tighter, mine will not even chamber a 311413 or the 311410. I have moved to a 311414, as it allows for a coat of PC and will still fit the bore. If you own an AR that will chamber it, more power to you."
So do we want to be .304 in front just for some fudge factor?
I know pc coating thickness can vary.
One last thing whatever we draw up we need to be able to hit the pin count so we need a design many will jump on with.
We have consolidated sizes so we pick one size.
Reason for this on a gas check bullet is if there are different diameters chosen made with the same cherry you will end up with a gas check shank that’s too loose to tight or just right.
The cherry is cut for one spec and non adjustable.
Figure PC is .002Quote:

300 BO Bullet
One size around .309
Not something that is a Swiss Army Knife, "good for 30-30, .308, .30-06......"
The 230 grain MP 300 BO group buy was a good size response
Thanks
