Berger load data?

[killman]

Why does Berger load data seem to be low?

Max load for my .260 rem with 130 grn vld is 43 grns of r19, yet Nosler list 45 grns of r19 for their 140 grn Partiton and a greater speed. I could only get 2650 ft/sec out of my 24" barrelled remington with the 43 grns.

Is this a dumb question?

I've just been reloading for a couple of months now, but in my experience all the manuals and data have been low.

In my .270 I've had to load 1gr (w/ CCI BR2 primers) over Berger's max for my velocities to be the same. On the other hand w/ Fed 215M primers I get the same velocity w/ .5 gr less powder.

So it might just be a variation in the power in the primer among other variables.

I just go up very slowly in ea. particular rifle until I start to see pressure signs, and use that info to set my max charge.

My rifle is a Rem 700 w/ a 24" barrel also.

Hope this helps.
