Interesting read about how many people are against long range hunting.
This is for reference of how far 600 yards is... Can you see my 36"X36" white paper at 600 yards ???
Its about the size of a black bear...
What about now at 55mm of zoom
Still looks like about the size of an 8.5x11 piece of paper.
I have shot 10 shot groups of 1 Moa at 600 yards consistantly with my rifle setup. These groups where shot in wind and weather... summer and winter.
The only way I would take the shot is after firing several rounds to verify that my settings are correct and have the proper equiptment to do the job... if your goal is to get a bear at 600 yards make sure you have the tools and skills nessary to do the job.
Personally after doing alot of long range shooting this year its possible to achive what your trying to do.
You need to remember that the bullet is going to take about .8 of second to get to your target so you want to make sure the bear is not going to move for a while.
I found it funny that some people would call the shot off if it got a bit windy... I have never been out shooting or hunting when its been dead calm and no wind... some people I guess dont know that you can account for wind. I would have to question these peoples long range shooting ability right off the bat. There is a thing called a wind guage and you can account for the wind... I guess they call off F class and tactical matches when its gets a bit windy out.
Bascially I have a chart taped to my scope cap that shows the exact windage and elevation I have to dial for the range I am shooting, this is not the kinda shot that can be made with gear you buy at canadian tire a 3x9x40 bushnell wont do the trick you need to have a scope you can dial and that is 100% repeatable... and if your knowledgable about mill dots it comes in handy when you have a target on the move or in between ranges.
The chart started out as a computed ballitics table for the exact load and rifle and was adjusted over months of target shooting... I know that the rifle and round combo are going to shoot where the scope chart tells it too... how I know this is after fireing hundreds of rounds with that chart and equiptment.
I want to recommend that my ballistics calculator gives optimum game weight usings 308 168 grain bullets traveling at 2700fps... of about 200Lbs I dont know how it comes up with this figure it just spits it out.
Realistically you might want to try and run the different bullets your planning on using thru a ballisitics program and find the one with the most energy and velocity that is practical for your application
Where I hunt we only can use shotguns so long range is about 200 yards with premium sabots and rifled barrels and leupold scopes... I also practice with my shotgun year round.. I know my limits off hand are about 125 yards and off a rest 200 because that is the limits of the slugs. I have yet to come upon a field condition where a rest has been used or 200 yard shot was nessary and complete sucessfully...
Bit about my 600 yard rig.
