OCW over max?

[Bartkowski]

I was looking at the data on the website below and noticed that a lot of the charges suggested are well above maximum. I understand that you should work up to the all charges listed but some of the data is over 5% higher than sierra's pubished data. Does anyone have experience loading to the specs on the website with good results?

Any input is appreciated.

Sierra's reloading data is EXTREMELY conservative. In .308 I use loads way over what they list as max.

I have found sierra's info to be conservative as well, but the data on the site is still at max for hodgdon or just above.

I'll use Hodgdon's data for Varget w/155s in .308 as an example.

They list 47gr as max, but at a short COAL of 2.775 for some reason. They list the same max charge for 150s. If you go to Nosler's site, they list 48.5 as the max charge for 150s. Quite a discrepancy there if you ask me. Use the reloading guides to get a starting point and then work up in your gun and if the pressure gets hairy then back off.
