Berrys plated bullets and a 30-30?

I was just reloading and since my father had bought some 30-30 RS FP from Berrys.

While loading, I figured I should go check to make sure they chamber. Since the other bullets chambered at 2.540, I figured these would to.
They did not.

The round I had chambered was without a crimp on it. When I went to check the COAL with my caliper, I had gotten 2.525. Im at a bit of a loss here as to what COAL it should be at.

Lymans shows 2.550. They did not chamber with the Berry bullet.
Lee second edition showed 2.550
Hornady showed 2.540.

I remember members told me Sierra was 2.520. Being that it pushed the bullet back from 2.550 to 2.525, Im guessing it would need to be at a somewhat similar length? This is where it is touching the lands?

There loaded with 27.5 grains of IMR-3031. Any help would be appreciated.

The most common fix to your problem is just seat the bullet deeper, shorter COL. http://www.berrysmfg.com/upload/bullets/30-30%20plated_tn.jpg

Variations in the bullet's ogive from one manufacture's style to another. Just seat them a bit deeper so they don't engage the rifling when loading. The difference will increase pressure but, unless you're bumping up against max loads already, it shouldn't be enough to cause any concern. The trick is to determine the correct length needed for your rifle before beginning to work up loads for it. Hopefully that's what you're doing.

When you say 2.550 is that the max COL or the suggested COL for the specified bullet.

Sometimes the COL for a specifiec bullet might be like. 2.350 for example.
Some bullets have a flatter ogive, and some have more wieght and are therefore longer. The COL is not always the same.

Snowbandit,

Yup, Low loads and working upwards.

243,

Just wanted to make sure. I was concerned about pressure.

Lovesbeer,

I know they vary but I was really curios as to why it happened when I put the Sieera FP bullet next to the Berrys one, The Sierra was a little taller.

I've bought Berry's bullets several times and they have always been great - except the 30-30. Didn't shoot for crap in my 30-30 or any other .30 bolt action I have. Tried half a dozen loads. Best I could get was pie plate at 50 yds. Think I finally loaded them up with some Red Dot and let some kids shoot them out of a 1903 for fun. Hope you have better luck than I did.

Most of the full power cast loads call for capping the base. Would think that the plating would eliminate the need but???

I like to load light cast bullets without the cap designed for the .30 carbine. Using slower pistol powders I worked up a load much like the old 30-20.

Light recoil and very accurate @50yds. I'm going to try it with plated after I shoot all the cast I have.

Anyone else try this?
