No one knew what the load was, so i salvaged the components.
The O.A.L or COL on the bullets were close to my gun, but the bullets were barely seated in the shell.
Through some research I have discovered the bullets are Sierra 180 gr FN.
I need to find data for reloading these bullets.
I am using Winchester 760 powder.
I sent Sierra an e-mail, but no reply yet.
Any help is much appreciated.
Thanx

Any listed Win 760 charge for any 180gr bullet should work, but work your way up as with anything.
For seating depth, seat no deeper than the cannelure (assuming these bullets are designed for 30-06/.308" application and not 30-30). As long as the cartridges fit into the magazine and the bullet is off of the rifling, you're good to go.

I've talked to a couple of guys who use them for elk, do pretty well with them.
Not long range bullets, but decent close in.

Thats my concern right there. If I dry seat them to the cannalure, they are
shorter than my O.A.L for my gun. I measured mine at 3.33 and these will seat at around 3.05 - 3.10
Not sure they will be that accurate with that much jump.

You might be surprised. In my experience round nose bullets aren't very sensitive to OAL. Load some up and give it a go.

I wouldn't worry about your OAL, unless you are measuring it from the ogive.

Thanx for the chart. Got my load range now.
We will see how they shoot.
Thanx all

Sometimes bullet jump has very little to do with accuracy. One article I read said that an experiment was conducted to see what deeper seating would do. As the bullet was seated deeper accuracy actually improved! The only way you'll know is to try them. As stated by other posts, if the bullet has a cannelure, use that as a seating depth...

I have my O.A.L. gauges for all my long guns.
We will have to see what they do.

Use any 180gr bullet data for the powder you want. Start low and work up. To find out col is a breeze. take a cleaning rod with a jag tip and run it down the barrel from the muzzle to the bolt face. Mark the rod right at the muzzle. Remove the bolt and drop one of the bullet's into the chamber. Run a wood pencil, dowel or what ever in behind the bullet to hold the bullet to the lands. Put the rod in again to the bullet tip and mark the cleaning rod at the muzzle again. Measure between the two marks and that's the distance from the bolt face to the bullet tip when stopped bu the lands. Set your seater die to that with that bullet and you'll have a load with the bullet just touching the lands. back off a bit from there to take the bullet off the lands.
:yeah: once you know your chamber back off 20 thouth and work either way till you get the accuracy you want or need. good luck. BTW measure bullets from ogive for chambering ;)

Is that where the O.A.L. reads the measurement?
I'm assuming the Ogive is what touches the lands..
