Here's an odd one.
I need to load some lead free ,06 rounds for a friend to take to Cali, tomorrow!
He's going to be possibly hunting Blacktail, bears & maybe a pig or two.

I don't have his rifle & other than a rough range trip to zero we don't have time to work up a load properly (I'm in TN, he's in IN & he's flying to Cali on Saturday)
Neither of us can find lead free ammo locally, so I offered to load up the 23 GMXs I have left. 3 to check, 20 to shoot.
I'm incredibly aware how sub-optimal this is....

I have most common powders available (IMR & H4350, 3031, 4064 etc) & I was wondering if anyone could point me toward a 'common load. I'm thinking 57gn of IMR4350 should pretty much mirror most factory loads at 2900fps +/-

I shoot gmx out of 308 with 4064. Extremely accurate.

We shoot 44 grains obviously in 06 that will be different. I think the max load in a 308 is 44.4 or 44.6 (don’t have my book handy)

I am almost certain my Hornady book has 60.5 grs of H4350 and the 150gr GMX. I do have testing data of 57gr H4350 with 168grttsx, so I don't see any reason why the Hornady data would be out of line.

Most gunstores near me (Northern Ca) have an acceptable amount of lead free ammo if your reloads dont work out. The earliest Rifle deer doesn't open for like 6 weeks so he's got time.
Here's hornadys book data
61.0 of h4350 should suffice and be stable since many of our hunts are hotter the hades

Here's a fresh new video I recently watched on the 165 GMX bullet and reloading it in a
30-06. This Ultimate Reloader is an interesting watch...these guys loves to geek out on the scientific shit.
