Guess?
Well, I finally got to shoot my first .308 reloads(ever) in my Savage 10TR. I was reloading once fired FED brass, neck sized in Lee Collet Dies. I only shot 100y. My normal urge to adjust as I shoot was set aside as I wanted to focus on my groups. The first group, at 42g, was a cold barrel.

I started from 42g IMR4064 (every load using 168g Hornady BTHP bullets and WLR Primers) and maxed out at 43.5g.

The Savage has a 4rd DBM, and since I wanted to shoot more than a 3rd group, because those that do face the wrath of many here... ;) I shot 5rd groups. I found that my adhustment to get that 5rd off messed with my setup on the rifle. I am not making excuses, just stating why the last round seemed to be a flyer each time.


Anyway. some pics. The odd round at 100y is the round not part of the magazine...at each load. At least I am consistent...

My best...the flyer being the extra shell I loaded singly. 42.5g of IMR-4064 looks good. I will test the same loads at 200y to be sure.

Nice. I did my first reloads about two weeks ago for my 10TR but it's been too cold to get out. Now that it's warming up here I'm heading out tomorrow morning to do my load testing. I loaded with IMR 4895 168gr BT Nosler starting at 39grs and went to 41.5grs.
 
What was the OAL you used and how far was the bullet from the rifling?

You've got a good load - now you can complicate things and try other OAL's and see if you can do better.

I stuck with what I had read in the reloading guide and online, and went with 2.80" OAL. To be honest, I am still not 100% certain at how to measure the distance to the lands properly.
 
I picked this tool up from Hornady and a special 308 casing that screws onto the end of the tool. You insert the casing into the chamber and push the bullet forward until it makes contact with the rifling. A slight decrease in length will then give the bullet a bit of a jump until it contacts the rifling.
For anyone using a mag you can only makes the cartridge as long as the mag will allow.

I going to try the poor mans method. Create a dummy round, and use a dowl to take a measurement with the round in, with bolt applying pressure, and one with the bolt fully closed. Watched 8541 Tactical do it.
 
Well, I took the measurement, and I am at 2.803. I know I will have to test some different seating depths, but if I understand some of what I have read, if I seat the bullet .020 deeper, that should give me a decent jump? I loaded up some cartridges with the bullet seated at 2.775 and 2.780, even though 2.800 did produce a decently tight group.
