7mm-300wm / 195 Berger loading data ?

[Cheese]

I’m new to this site and I’m excited to communicate with experienced shooters. I’ve built a long range rifle and I’m looking for loading data for 7mm-300wm with 195 Berger. Any info out there?

 

[INTJ]

I am surprised no one has answered yet. Have you contacted Berger?

 

[Cheese]

Yes I talk to them all the suggested was powder and they couldn’t help me any further because it was a wildcat

It's very similar to a 7 RSAUM. Use that load data as a starting point. What discipline are you shooting? Hunting?

This gun is for long range (1000) yards and out

I’ve found a couple threads they were around 80 grains start point

aka 7mm Practical

Originator shows 70 to 73.5gr of H-1000 or RETUMBO is where he's at.

Unless you're talking about 7mm-300 Weatherby and not the 7mm-300winmag

1000 yd hunting, plinking or some kind of competition?

Yes mine is 7mm/300 wmag and I’m plinking right know until I get this dialed in. I did come across the 7mm practical, read up on that a little but wasn’t specific enough for my brass. Did find some interesting info on long range only.com recently. I appreciate you doing some digging for me I will keep looking

 

[INTJ]

Oh, 7mm-300 WIN Mag. I would think you could start with 7mm Rem Mag loads then

80 GR would be to high for a start point. I would start about 72 and prob end up around 75gr of Retumbo

The practical and the 7-300win are not the same thing. They are close enough for starting data. I started with 73 grains h1000 with 180s in my 7-300s. If I were using 195s I would drop another couple grains for starting. I do not think you are going to push the 195s fast enough to outrun 180s.
