Just a Little FYI on CR-123 and CR-2 lithium cells:

1. Buy made in America. ALL CR cells made in America are produced by a single plant in Columbus Georgia. Owned by Panasonic they make , Energizer, Duracell Surefire etc....All the same except price and label.

2. If you cannot buy USA, Buy Japan. Stay away from, European and Chinese cells.

3. My testing has been down to -40C for most military applications the CR-123 cells have performed at -30C(-22F) and very well at -20C(-4F) even under heavy loads that would exceed a Laser rangefinders loading.

4. These cells don't go bad. I have 2002 vintage cells and they are still performing at >98% of cells produced in 2010. I stocked up as I get them for less than a buck each....

5. Stay away from ALL rechargeable versions of these CR-123 and CR-2. Trust me. They are waste of time, money and are not safe.



I'm really interested in a G7 but I'm gonna wait until they combine the Laser into the Binoculars. I really hate carrying both and on my S.Africa hunt it was very difficult terrain to re-acquire a Kudu in your LRF after setting down your bino's.

Do we know that this is in the works?

Re: Gunwerks G7 BR2 Rangefinder Review

Question, for those of you using this the G7-BR2 to replace your kestrel and pda's and ballistic programs. What do you do for your windage solution? Does it have a way to enter a wind value and will it give a correction in MOA?

Thanks
Jeff

I read it has inputs for wind in 5mph increments. It has to be manually entered.

Now that you mention that I kina remember reading that too. But I must have skimmed over it pretty fast. Five mph increments seems like a large step especially at the longer distances. I wonder if that can be changed?

Thanks for the reply

Jeff

Re: Gunwerks G7 BR2 Rangefinder Review

After it has given you the yardage then the dail correction you can then use the arrow keys to scroll through wind values in 5 mph increments 5-50 mph. I have had no trouble using the 5 mph increments.

Thanks Shawn, I have a friend that I do some set up for and he called me yesterday and wants me to get him a new RF. We talked about the G7, Leica 1600, and PLRF05.

I just ran these number with my .338 LM and a 300 Berger. I chose it since it bucks the wind best.

Full value wind @ 1000 yrds.

5 mph = 2.6 moa
10 mph = 4.8 moa

So a 2.2 moa / 21" difference at 1000.

A 7 mph wind is 3.5 moa. So in this situation would you feel it would be best to look at both a 5 and a 10 and split the difference?

If I did that it would be 1/2 of the 2.2 which is 1.1, and adding it to the 5 mph correction of 2.6 I would come up with an end correction of 3.7 which is closer that I can read the wind anyway.

Plus, I don't see us taking many shots at 1000 or farther on game in much worse contitions.

Thanks
Jeff
