Is that crimped?

Yes I put a bit of a crimp on them using lee factory crimp die.

How much of a crimp should be put on these loads?

I wouldn't crimp them at all unless your shooting it out of a tubular type magazine or an semi automatic action. Oh or a handgun,, revolver/auto.

Darkhorse,

That is some fine riflery. You definitely have a good load in hand. I should imagine that deer are in trouble in GA.

Thanks for the compliments. I am hard to please when it comes to accuracy. I remember stressing about elk loads shooting .525 with my .300 Win. as it had shot better. Then I thought "How many other guys in camp will have a rifle that shoots .525" groups?" So I left it as was and ended up shooting a nice bull at 400 yds. I guess I"m just obsessive about some things.

These are not my hunting loads. These loads were to check the condition of the barrel and my bedding job on a rifle that had been a safe queen for a decade, and had a severely warped forend.
These loads were 60.5 gr. IMR 4350, my hunting load is 63 gr. IMR 4350 and they come in around .630 if memory serves me. Interesting tidbit, at 63 gr. the regular Ballistic Tip wouldn't "settle down" and gave over 1.0 groups. But when I tried the Combined Technology Ballistic Tip I was able to get those to shoot well under an inch.

I never crimp any centerfire cartridge unless it's going into an Auto. FWIW
 
I was under the understanding pistol, lever, and magnums needed crimping.

I use The Lee crimp on most loads. But On the Etip I will use a very light crimp. Just enough to stop set back. The 7mm rem mag recoils hard enough to hammer a Bullet back into case. The only down side to crimping is it can shorten brass life. But on Hunting ammo that is really not important.
 
I like the FCD, especially with slick mono bullets. In fact, I crimp everything now, regardless of bullet and I crimp them hard enough to see a good crimp. It doesn't hurt anything in my tests/uses, and I can't tell it has shortened my case life any. I usually see a better burn/bullet pull as I just use standard dies and hunting rifles, I wouldn't dream of using a FCD on a dedicated benchrest/varmint rifle, and have had a few through the years. In my hunting rifles I've done it both ways, but I shoot a lot of compressed loads and I like how a crimp keeps the overall length constant, keeps them "from growing" I like to say, ha.
