30 Cal .308 DIA 168 GR TMK #7768 load data

[pathfork]

Can someone help me with a starting point on some load data for these Tipped MatchKing's please. I have been looking for 2 days and nothing nada zilch. I have looked in every reloading book and googled it every way possible. Can somebody give me a min - max on powder and O.A.L please. I am wanting to load these for a M14 and possibly a 1960 Winchester Model 100 semi auto 308. Below are my components options

Brass (Trimmed between 2.005 and 2.015) also this will be the first time this brass is reloaded
Lake City
Federal Gold Match

Primers
Winchester LR
CCI LR

Powder
Prefer IMR 4064
IMR 4895
Hodgdon H335

I appreciate anybody's input here

The Tipped MatchKing bullet is a recent model. It was born after the M14 and Garand hit their peak and were largely displaced by the AR15.

It isn't that you won't find folks using them in their M1A or Garand, but since the use of The Wooden Guns has slowed by comparison to the times when those dominated the field, publication rates have been on a decline.

That said, you can always run the same data as the regular MatchKing as a starting guide.

If your rig is typical, you will get typical muzzle velocity within the same spread that those rigs give even when running regular MatchKings. There is always a dispersion above and below the published data, so don't confuse the normal range for something abnormal.

Start low and work up while studying the ejection pattern and brass. If you have a chronograph, even better.

Here is a little focused guide to match M14 loading. Stick with these Pet Loads till you get some experience.

I don't think I have loaded for a Winchester Model 100, but I would start that the same way with similar recipes. If you have 4895 and 4064, I would start with those. These same guidelines worked with several Brownings in 308, so they should be fine with your Winchester to start out.

I shoot 175 TMKs 41.7gr IMR 4064 in a 24" Krieger 4G bolt gun. Very accurate.. my 169 SMK load with 4064 is 42.6gr same gun.

So work up from 41.5gr 4064

Look at 168 Amax loads for gas guns. Start low and work up. These are longer than SMK 168 and you will have more bullet inside the case.

Thank you and especially for that PDF I've never seen that. I read everything I can for M1 Garand and the M14

I wanted to say thank you to everyone for taking the time to answer my question.

A note on the data for the 308 M1A and Garand Loads. One of the publications was working on M1 loads and discussed mentioned to a friend at Capstone ( the distributer in the US) and mentioned N150 and he was advised that N150 was too slow for the Garand being closer to IMR 4350 in burn rate. This advice probably goes for the 308 M1A as well.

I have not considered using TMK's in an autoloader. I assumed their secant ogive design which often works best seated near the lands would be a problem at magazine length. My 308 bolt guns work well with 168 TMKs, but that's at 2.940-2.960 oal.
