K31 Reloading help again! Bullets are too big?

[Latigo]

Good moring, Uncle Ray.
Its not meplat position, its the fact that the edge of the meplats are uneven, and that's what can make a difference of 2 to 4 thousandths. If you're indexing on an uneven meplat tip and not indexing on the ogive, you're not going to have the accurate seat depth you're looking for.
Uncle Ray, we seldom use our GP11s. We've equaled and surpassed the GP11s known accuracy and consistency using 175gr Berger VLDs. The VLD is virtually a carbon copy of the GP11 projectile with the same very long nose. Fortunately for me my Dad bought some 5 thousand of them very long ago when the prices were at $17.00 per 100. Those same projectiles are now in the $52.00 to $56.00 per 100! I couldn't afford to do the load data gathering I now do at that price!

This is our projectile prep:

Anything out to 300 we don't necessarily do this, but beyond that range we do.

This is our process. Your's may vary, but this has proven itself for us.

Projectile prep:

We only use Berger VLDs, but Sierra SMKs work really great too. This particular sequence is with a 175 SMK we're loading for a Wilson long range AR10.
Our method is to begin with meplat trimming. We use the Hoover. Buy the sort that indexes on the ogive, not the base of the bullet. That's going to be very important when you cross reference/compare actual seat depth from the ogive to COAL, cartridge to cartridge later.

Untrimmed and uneven meplat



Trimming process.



Trimmed



We then use a Hoover Pointer to reshape and center the hollow point and we taper it down to an opening that's approximately twice the thickness of the jacket wall.

Pointed correctly



This is only the beginning of our overall case/projectile prep process.
Thanks for your response, Uncle Ray. My Dad has been in your conutry a number of times in the late 50's when he was still sailing merchant ships.
