today was sunny up around 70
and had Major pressure signs bolt extremly hard to lift primmer flat
So ill be backing hte load down to 63 gr to where i started.
The WW 2 H4831 was my favorite in a 7 rem mag with 67.5 grains behind a 168 SMK.

The newer H 4831 had to be reduced to 65.5 grains and stilled matched my velocity.

When I switched to H4831sc I had to reduce it even more to keep the pressure with
in limits.

64.5 is still a hot load and will cause problems if it is left in the sun or a hot car.

If you are seating close to the lands this could cause pressure to be on the high side.

Ouch! If that hood is painted anything but white, I would guess the cartridges may have warmed up a fair amount.

Re: signs of pressure

the truck is silver and we use a grey blanket of the hood
Now im not sure backing back down to 63 gr will be enough
according to berger the load range is 61 to 64.5 so 63 is in the middle.
also im 20 thou off the lands
