The great 70-77 grain competition

[aklaunch]

Sorry folks, I don't have any data to display at this time. This thread will likely take me all of 2014 to complete.

I have all of the components on hand to do an accuracy test at 100, 200 and 300 yards.

This test will display the muzzle velocity of the most accurate loads. And then maybe a notch or two above that for a bit more velocity. Even if accuracy opens up a bit.

Bullets:

Barnes TSX 70's
Speer TNT 70's
Swift bonded spitzer boat tail 75's
Hornady HPBT 75's
Berger HPBT 73's
Berger OTM TAC 77's
Lapua Scenar 77's
Nosler Custom 77's
Sierra MK 77's with and without lee crimped cannelures.
JLK 77's

I have all of these in my possession except for the JLK, Swift, Berger 73's & Speer bullets.

Brass:

Nosler brass for Nosler bullets
Lapua brass for Lapua bullets
Hornady brass for Hornady bullets
Norma brass for Berger bullets
Lake City 2009 brass for Barnes
IMI brass for Speer bullets
Federal brass for Sierra bullets
Un determined brass for the JLK's
Un determined brass for the Swift Sciroccos



I will likely mix some Lake City 2008 and 2009 nato stamped brass as well.

Primers:

Primers will be what the book calls for.

I have a good selection of Winchester, Remington, Fed 205 and CCI 450's + #41's

I may mix and match a bit when i use the Lake City brass just for experimentation reasons.

Powders:

Again what the book calls for.

I have all of the popular ones on hand at this time except for TAC and RL 15.

Rifle:

I have a heavy barrel Mark 12 which is a very good quality 18 inch barrel. It has around 1300 rounds through it since new.

Also I have a couple of carbines in the 16 inch barrel length.

Last but not least is the 11.5 inch short barrel rifle.

Most tests will be with the MK 12.

Reloading Manuals:

Lyman
Sierra
Berger
Nosler
Speer
Hornady
Barnes

About me:

My shooting abilities are the right on the dead center of average.
I have reloaded around 4-500 rounds total and am new to this hobby
I have researched all of the above manuals thoroughly and carefully.

Reloading equipment:

I have an RCBS rock chucker reloading press.

I use Forster FL sizing dies, and the Forster Ultra Match bullet seater now.

Hopefully by the end of March. I will have the data out for at least one of these.
