Two diameter GG bullets

[rdnck]

Richard--Re read Don's post. At least twice. You are way over thinking this, and trying to re invent the wheel is only going to extend your learning curve and keep you chasing your tail much longer than necessary. After it is all said and done, you may very well wind up using a Lyman Postell which is a very good place to start with your rifle. You would be surprised if you knew how many experienced shooters use that bullet. Shoot straight, rdnck.

Don, Rdnck,
Lol, you don't have to hit me too hard on my head to get my attention.
When Don mentioned the 459525-M3 bullet from BACO I looked at their website and saw it was not in stock so I kind of blew it off to look elsewhere. After the second whack ;-) by Rdnck, I called BACO and spoke with Brandon and he said there might be a 4-6 week wait for that mold. I plan on ordering that mould on Monday along with another mold and some other items; wad punch powder compressor etc. regarding the other mould. It will be a lighter bullet for chickens, fire forming and offhand practice. The two moulds I am looking at are BACO #459370 or #459435. I'm thinking the 459370. What are your thoughts? BTW, the twist is 1:18, 30" bbl.
I already have plenty of new Starline brass that I have to anneal, a brick of CCI BR-2 primers and a case of Swiss 1 1/2 powder.
What would you recommend for bullet lube and wads for a starting load. I understand from reading that Swiss does not like too much compression.
PS, I the moulds drop the bullets at .459 should I get a .459 size/lube die?
That's it for now.
Thanks guys Enjoy the weekend.
Regards, Richard

If you cast with 20-1 alloy, those BACO moulds drop at their specific diameter. So if you order a .459 mould a .459 size die will be just right.
One thing with the BACO moulds listed on the website, most of them say not in stock backorder ok. They don't keep a huge inventory on hand, but as quick as someone orders a mould they put it in line to be made. Seems most of the time it takes about 2 weeks, just depending how backed up they are.
.060 fiber wads are my favored. There's a plethora of good lubes out there, I like the Bullshop Nasa lube, and Big Sky Components BSC.
This bullet shoots very well in my Browning and my wifes Winchester bpcr

Richard,
plenty of stock of 460535m5.
it would go into your 459 sizer ok.
keep safe,

Bruce, I spoke with BACO the other day and told Brandon I was going to order moulds from him on Monday so I am committed mould wise. Maybe next time .

Richard,
rule no 1: "you can't have too many moulds".

I think if one is going to play in this game, I'm afraid your correct on that comment Bruce.
When your seating bullets deep into the case is it best to have a good inline bullet seater or have you found that the standard seater in a die set is OK. Do you dial your complete cartridge to see what the TIR of the bullet is?
Thanks, Richard

Richard,
I must confess to shooting pp bullets which feed into the bore.
because I don't have a pp chamber, I have evolved a dual diameter bullet which patches to groove diameter where it is in the case.
I do not size the case, just finger seating the bullet, and letting the bore set up alignment.
when I shot greasers, I used a file trim die backed off to minimally size, and then expanded the neck, just a little, with a baco 2 diameter expander.
the larger diameter allowed the bullet to start, and the smaller diameter was the same as the bullet.
with case springback this gave 0.001 neck tension.
it was enough tension to go hunting with.
I have done this with pp bullets as well, but for target shooting it is just unnecessary work and is probably less accurate than finger seating.
ammo runout is possibly not worth worrying too much about, as there are many things like holding and squeezing, using the optimum sighting element, and consistent barrel condition that can make a far greater difference.
I once tested some ammo in my fclass rifle with 0.008 runout fireforming cases against some with 0.0005 or less, and could not really tell the difference.
if you are going to chase runout, in the real world you need to neckturn the brass, and this is only useful in very specialized situations.
I do dial fclass ammo, but that has a far greater accuracy requirement than bptr. however only some rounds to check that nothing is awry.
when I started bpcr, long bore riding nosed greasers were de rigeur.
if I have learned one thing, it is that they bump into the rifling and can leave lead in your bore.
this happens less so when blowtubing except on the first shot.
an experimental bullet I had brooks make, with the bore ride having grease grooves, had no such problem.
keep safe,
bruce.

Bruce,
Thanks for the informative reply. I am slowly getting my reloading gear collected and will post my results as they occur..the good, bad and ugly.
Regards, Richard
