208 amax jump or jam?

[Onemoretime]

Where are you guys running these? They don't shoot as well as the smk's in my rifle and I'm hoping it's a OAL issue.

I read MM is seating them .01 off the lands, is that what most are doing?

In my experiences, AMAXs like a kiss of the lands. I never had much luck "jamming" or jumping them.

"kissing" meaning just touching or a 100th off of them?

Just touching.

My 208 AMAX likes to jump just a "little bit". I am loading it to mag length 3.600" (300 WM), the chamber legnth is well above 3.700". My AIAW 308 shooting the 208 AMAX is loaded at 2.940" and the chamber length is 3.024". They all shoot well. Go figure.

Gotchya. Do you ever worry about in variations in ogive?

I'm running a 30-06 so mag length is not an issue for me. I don't have a oal gauge so I might be able to find out what kissing is for a 208 in my gun when I visit Randy this weekend.

I think the consistency of manufacturing ammo, especially Hornady is quite good, so the variation is very slightly, if any.

Nope.

I measure to OAL since I don't have an Ogive jig. I shoot mine with a 0.005 to 0.000 "touch" for the best results.

Anything more than about 0.015" and the accuracy falls off. If I jam them they suck.

Load mine .010" off lands.

Re: 208 amax jump or jam?

I shoot 162's in 7mm at .010 off. I tried from .015 which wasn't much different accuracy wise to "kissing" which opened up my groups.

I shoot .02" off. That generated the best accuracy for me there..so far
