GREAT... supposed to be pet LOAD.. cant fix it either with edit!!

Since I can't get varget, I bought 10 pounds of this stuff.
It doenst meter as well as varget.
I'm using once fired LC Brass
Large STD rifle winchester primers
and 147 grain FMJ and/ or
150 BTSP Hornady

I loaded up 45.0, 44.5, 44.0 and 43.5 loads
was going to test them last week in my M1A withe my Oehler 35 P chronograph.
Well, I put some 38's and 44 spcls through the Chrono.
I friend put his .223 thorough it.
we were picked up brass and all was well with the world,
when I went to get out the M1A my friend says, Hey, what's with this, and my sky screen upright was shattered. It WASN'T when we fired the last shot.
So... I didnt get to test those.
TODAY, my sky screen uprights arrived. I bought 6 (all of em) new just in case they got brittle with age. I"ve had the unit since about 1985 or so and NEVER shot a sky screen or had a problem.
Go figure!!
Anyone GOT a pet load they want to share with me using IMR 4064 in the 7.62 Nato case with 150 grain bullets??
BTW... I was using 45.0 grains of Varget with the 150's and they were EXACTLY 2760 almost (within 20 FPS or so if I recall).
The powders are on the same burn rate almost.

This isn't a "pet load" but might help.

Hornady has a section in their manual specifically for M1A type rifles in .308/7.62mm NATO. Their data for IMR 4064 goes from a starting load of 37.9 gr. and a maximum load of 43.2 gr. with their .308 155 gr. A-MAX bullets. Muzzle velocity with the 43.2 gr. load is listed at 2,700 fps.

I use 4064 powder exclusively because I don't reload much, it works well in the three rifles I load for (30-06, .303 Brit. and .250 Savage) and is generally available. You're right, while it is versatile it doesn't meter well at all. I trickle up each charge.

If you can find IMR4895, that meters better than 4064. 4895 is the classic powder used by XTC highpower shooters before the AR took over. Varget is basically IMR 4895 without the temperature sensitivity (but use each powder's load data!). I'm seeing 4895 in a lot of places now.
