Seating long bullets...really really long bullets.

[Goofyfoot2001]

Ok so I bought some factory second 230gr for my 300blk a few months ago. Turns out the tape is so long from the tip that they are too narrow for the neck unless you seat them so long they won't fit in the magazine.

So I says to myself, "You can use em in your 300WM boy o boy o boy."

Well they are really long bullets so it scared me a little know that the butt end of that bullet is way way past the neck and into the case so I ended up make a few rounds that had to be fed one at a time cause they wouldn't fit in the three round mag either. They seemed to shoot ok and fairly accurate; groups of no more than a few inches at 100yrds. For freakish bullets I am ok with that.

My question is, and I think I have asked this before; what are the ramifications of having a long bullet sticking far into the case? I will post some pics when I wake up enough. Need coffee.

Takes up case volume, so start low on powder and work up carefully. If you hear a crunch while seating the bullet you’re compressing powder.

Wouldn’t mind trying these in my 300blk handi rifle, willing to sell some?

I use them in my handi.
It (the handi) has a freakishly long leade.

Unfortunately It's the only box I have and half of that is gone. So what you're saying is that if it isn't compressing the powder, it doesn't matter how far into the case the bullet is going?

It doesn't really matter in rifle rounds, neck expands and bullet is released well before peak pressure is reached. Unless of course you are also jamming the lands and therefore the bullet cannot move forward and gas is restricted more bypassing the projectile. Always wise to start lowish anyway.

For the record, I have no idea what I'm talking about. But....

My uncle had a .308 "sniper rifle". He loaded his own bullets for it. He had two different kinds of bullets. One kind fit down in the magazine. But he also had a dozen or so that were for loading into the chamber without ever being in a magazine. They were (intentionally) too long for the magazine.

I don't recall why he did it. But I do remember that they were in a separate box and that he had done it intentionally.

So maybe you can load some that are too long and made only to put directly into the chamber?

Just to mention it, some rifle powders are ok to compress, extruded Types come to mind.
Varget, 4064 etc.
I've got some great results from compressed loads. My theory is that it causes a more uniform burn due to less air pockets.
(Just a theory, zero proof)

My pet 6.5 Grendel load is compressed as well, 31.5 gr of BL-C(2) fills the case up to the bottom of the neck and I get a “crunch” when I seat the 123gr ELD Match bullet, the load data is on Alexander Arms website so I gave it a try, it is the best shooting load I’ve shot so far.

Ok so my question might not matter in the end. Now I remember that I loaded some really long to see how they would do and they did ok. The reason I did was because I couldn't seat them deep because the tapers is still too long to allow for seating deep enough to fit in the mag; the bullet would still be too narrow at the neck of the bullet.

Also the size of the bullet next to 300blk.
