Default RE: 100 gr. verse 150 gr.

I'd expect it to hit a little higher than the 100 grain load at 50-100 yards. There is a really nifty ballistic calculator at www.handloads.com . You have to know the ballistic coefficient of the bullet you're using (most manufacturers give this data, but the bc calculator will also provide a rough estimate). It'll spit out a spreadsheet with balistic info out to whatever range you specify.

Here is an example of the load I use for my Knight:

Of course, this is just an estimate of actual balistic performance, so you really need to shoot the rifle to get the actual ballistics down. I used the above chart to get my 100 yard zero close while shooting at 30 yards. I can tell by the chart that rifle should be very close to zero at 100 yards if zeroed at 30, without having to waste a bunch of shots just trying to get it on paper.
