Accurate clone of Saeco #315

[Rockydoc]

I am in the process of ordering a clone of the Saeco #315 from Tom at Accurate. Part of this ordering process is specifying the diameter of each of the bands. This is a tapered bullet so the bands are different diameters. I have no idea what the diameter of these bands need to be. I would be interested in hearing an explanation of how to determine the size of these bands, as well as any recommendations. I intend to powder coat these bullets.

This is for a Ruger #1, 30-30 Winchester.
The bore, measured at the muzzle with pin gauges is .299” Go, .300“ No Go.
The groove diameter measured from a pound cast is .3085”.

I need help here.

Mine is a SAECO.
I didn't request the bands to be a certain diameter.
SAECO cut the mould and " I got what I got ".
However mine shoots great in about 20 different .30 cal. rifles that I've tried it in, including my Ruger # 1, 30-30 Win.

I think I have one of those made by NOE maybe. I've never gotten around to trying it yet.

Pound cast the throat and chamber neck BEFORE you make any assumptions.

Powder coat can add 1.5 to 4 thousandths depending on powder type and how it is applied. Have all that worked out before ordering.

Powder-coated bullets tend to like being about 1.5 thousandths larger than groove diameter, or 1/2 thousandth smaller than throat entrance diameter.

I think I have a SAECO #311315 in 4 cav that I might be talked out of.

I have done a pound cast. This was mentioned in OP.
I don’t really consider a SAAMI 30-30 Winchester chamber to even have a throat. How would I use the “throat” and chamber neck dimensions in deciding what to request for band dimensions?

Thanks

Thanks, Ben. Accurate requires you to specify

Thanks, Ben. Accurate requires that you specify band dimensions when ordering a custom mold. I am not sure I would want the same dimensions that work for you since you use traditional lube and I want to powder coat.

Yes, this has already proven to be true for this rifle. It has a groove diameter or .3085" and prefers .310" powder coated bullets.

How would the following look for band dimensions for my #315 bullet to be powder coated for my Ruger #1 30-30 which has a bore of .2995" and a groove of .3085"

Let's assume that powder coating will add .002" to my bullets.
The nose should be .2995" minus .002" equals .2975".
The base drive band should be .310" minus .002" equals .308"
The bands in between should taper from .2975" to .308"

How does that sound?

 

[Ben]

Should work fine.
Yes, I'm not a powder coater.

" I have done a pound cast. This was mentioned in OP."

From what I gathered, you only slugged the barrel. Need to know what kind of throat and chamber neck dimensions it has to recommend band diameters.

 

[fiver]

it doesn't have to be tapered, and it doesn't have to be exact, your size die will fix .001 without it being a world ending catastrophe.
that .305 and .302 section Ben shows is really the only section you need to be worked up about, they are set like that so you can seat the bullet out of the case in various rifles with more worn throats.

I was going to order the Saeco # 315 on Ben’s advice but they were out of stock until who knows, Redding didn’t. I tried going to Accurate to order one and ran into your problem Doc, could not figure out what to specify for the bands. I intended this bullet to be a low to medium velocity projectile in a wide range of .30 caliber rifles. I took a little more of Ben’s advice and just ordered the NOE copy in plain base. This bullet has been fired in everything from .300 Blackout to .300 Weatherby with results that are good to outstanding. I don’t powder coat anymore so I can’t help there. The biggest issue I’ve had with this bullet is figuring out how many grease grooves to fill. (hint it’s 2-3 grooves) and a single sizing diameter which turned out to be .311. Seating depth doesn’t to be a big factor. So seat the bullet to cover the grease grooves. If it chambers with no feel or just a bit that doesn’t pull the bullet when extracted I’m set. It works well as a 50 yard target bullet unsized and a coat of 45/45/10 and a second coat of Ben’s tumble lube (original recipe) Using 5-6grains of Bullseye and small pistol primers in .30/06 will shoot into 1” or less with most my rifles. This is a very versatile bullet and is easy to make shoot well.

I also have the NOE #315- clone, that drops both gc and pb bullets. Mostly, I have shot these bullets with regular lube. And they shoot good or outstanding in everything. I have also shot a few with powder coat; gas checked, plain base and checkless (the latter referring to GC design, shot without GC installed). Results with PC have also been good- but just a few groups so far.

OK SO! I have a NOE 315 2cavity GC , I size it .310for the .308 and .30/30, .311 for most of my .30/06's. HOWEVER, I wish I had gotten one from Tom with the .311bands sized to .312so I could use it in more of my Springfield's. I believe this is what Ben did when he ordered a 2 cavity brass PB from Tom . My .30's need from .310 to .313to shoot GREAT. I can always size down ,but can't size up, I don't pound cast but rather load 10 sized .310 .311 etc and let the target tell me what the gun likes.BTW the 30/30 just loves and I mean LOVES , The PB

 

[Ben]

and let the target tell me what the gun likes.

Young cast bullet shooters ( and a few older ones ) often get caught up in velocities, powders, bullet styles and old wives tales and fail to realize this one important point.

I gotta get my butt out and cast. I have that NOE 315 clone and there's a brandy new NOE copy of that taper tailed Pope finger seatin' .30 caliber Springfield bullet here somewheres that has never been used.

I got all wrapped around the axle with the Lee 312-155-2R and the XCB shootin' out to a quarter mile. Hey wait a minute, that's fun. Ya know the clone I really need is a clone of me with a shared consciousness and joint ventures. I have more things that need doin' and not enough of me to go around.

So mewhere around here there is a thread where I worked up loads with the NOE version of the #315 in my old JC HIggins M51-L (Husky HVA action). Throat and bore was a bit oversized, I ended up sizing at .311-.3115. Powder Coated, 3% Sb, water dropped out of the powder coat curing oven, I ended up with some decent loads, a couple above 2400 fps. Took 3 does with it last year and never recovered a bullet, even on the two shot facing me straight on.

 

[Rockydoc]

Here is a photo of my "pound cast". The groove diameter is .3085". The case neck is .3345". The section between the case mouth and the rifling is .3325". I don't know what the correct name for this last section is. Is that the "throat"?

So with this information, what should be the diameter of the bands on this Accurate clone of Saeco #315 be when powder coating is going to add .002" to all the diameters?
