The Accurate 31-175BP
In my opinion, this could quite possibly be the best plain base .30 cal. cast bullet out there. I've shot tons of plain base .30's. If there is a better one than this one, I'd love to try it.

I have the somewhat simular bullet from NOE. This is one of those rare designs that shoots well in all rifles I've tried it in, both as PB and GC (I have a 50/50 4- cav). Love it!

I'm not certain that I've ever used this bullet design in a .30 caliber rifle in which it did not perform well.

I have a 4 cavity gas check version of that Accurate mold. I have some powder coated, without the GCs, with your 7.2gr Bullseye loaded up that I haven't shot yet.

I don't know if the checkless version will shoot as well as the PB version. We'll see? Have any of you tried this?

I've yet to shoot a cast bullet that was designed for a gas check and not put a gas check on it that shot well.

Ben
If that turns out to be true in my case I may be wanting you to do some of your Plain Base Magic on a couple of cavities on that mold.:)

Ben in most standard (unwarn) chambers how far out do you seat the bullet?
The only case i have tried it in is the 308 and it does purty darn good, even up to hunting velocities.

Kevin,

I ( if possible ) like to take the wide front driving band and lightly imprint it into the rifling of the barrel. However, not enough that if you extract a loaded round it will pull the bullet from the neck of the case.

I’ve not done extensive testing with coated, checkless bullets of this variety- but I’ve done a small series of comparative groups. Groups (PC/PB vs PC/checkless) were identical, but slightly bigger than typical groups with lubed bullets in that particular rifle.

So you are saying that you get better groups with lubed bullets than powder coated bullets, all else being the same?

Yes, that's correct - in that particular rifle.

When we add coating to a bullet, we add girth; typically 0,002in diameter, everywhere.
This affects fit; sometimes for better, sometimes for worse. In a way, it's not "the same bullet" anymore.

With the NOE311-179 (#315- clone) in my Howa .308win, accuracy seems to be the best with regular lubed bullets, so far. In another rifle, this might as well be the other way around.

Tapered multi-band bullets go way back. When the Shutezen game was afoot, Pope and others furnished molds of this design with their rifles. Loverin picked up the idea and applied it to his design of molds. Then SAECO got ahold of the notion and came up with a terrific design or two.

Everything old is new again and some things old are better than many things new.

In general I’ve found the Saeco #315 and it’s clones shoot better that any Lovern design that I’ve tried. My NOE copy is a four cavity plain base that shoots well in everything I tried it in. I tumble lube and shoot it as cast. It and my Saeco GC #315 (with gas check) do slightly better sized to .311 with just the first and/or second grease groove filled.

There is something about the Saeco design that’s different. I assume it’s the tapered nose and long solid base…….????

The issue I have had with Lyman Lovern molds is that they are Lyman molds, i.e. the specs are all over the map depending on when the mold was made. The top bands are larger than the SAECO 315 top bands. Too big to engrave on the rifling. When I started sizing the top two bands of the Lyman 30 Cal Loverin molds .301 - .302 accuracy took a big jump...I mean a big jump. This let the top bands engrave on the rifling and allowed the bullet to be seated farther out in the case.

At the casting bench in the sky. RIP Bret.
Believe you're right Charles. When you get a good fitting Lyman, they're great. If you get a poor fitting one, not so much. But that seems to be par for the course across the board. At least you figured a way to make one work.

These are some results of my checkless powder coated Accurate 311-175B clone of the Saeco #315. Fired from my Ruger #1, 30-30 Win at 50 yards.

Load is 7.2gr Bullseye, a load suggested by Ben.
. This is .8" including flyer, .5" for 4 shots.

IMG_0793.jpgThis is .9"



IMG_0794.jpgThis is 1"IMG_0795.jpgThis is 1.16 total, .75" without the flyer.

This is acceptable accuracy for me without gas checks for plinking.
