6.5 PRC?

For high volume target shooting on a budget, the creed would probably be a better choice considering the cost of barrel replacements. Most hunting rifles will never need a new barrel.
AGREED. My last 6.5-284 barrel was toast after 1,200 rounds.
That you don't shoot animals past 400 yards is one of the best things I have read in a long time.
I shoot about 5000 rounds a summer in F-Class to 900 metres. 990 yards for the rest of you.
When I took my first 1000 yard shooting courses in the early 1990's our Late Instuctor said he would not personally risk an injured animal past 500 yard and the he promptly shot a gopher at 963 yardswith a 40X Rem In 308 Win.
When I write down every shot and scope setting I have had 6 MOA difference depending upon air temp. That is 60 inches diffence. When you have a limited time at altitude and weather, it takes an expert to hit a target past 400 yards without sighters.
I love my 6.5-284 to hit gongs at 1200 yards once I have a couple of sighters.
Hunt under 400 yards. If you can't stalk closer, 99% of people will wound and lose game. Just talk with a few camera men who have filmed some of the TV shows. They only broadcast the kills, not the 6 wounded animals that ran away never to be found.
The exception is a wounded animal someone else shot and was running away. As witnessed was moose at 525 yards going staight away. Another hunter spined it and we had a long day after that.
Nothing ruins a moose hunt like killing a moose.
Shoot as far as you can on targets....get closer on game.
An old hunters opinion and just an opinion.
Just checked my 308 dope for 168amax. If I go from 0 density altitude to 4500 density altitude, which is a swing from -15c to +25c approximately, I have a shift of 4.25 Moa at 1k. You've shot through quite the temp swings, must've been windy
I use Litz's bc for amaxsWe sure do have huge temp swings where my club Range is.
The other thing is that every ballistic program I have ever tried is overly optimistic at long distance. I have settled on iSnipe and even then I go back and try to "force" it to fit my notes. My 155 scenars come out around 2950 fps. As chronogtaphed. When I try to force fit my come ups at 300, 400, 500, 600, 700, 800,'and 900 m the only way to get a close match is to lower the velocity in the program inputs to fit. Sometimes as much as 200 fps in the program. G1 is really incorrect at long ranges. G7 is way better but still not perfect
When we shoot electronic targets, they have sensors that report the velocity at the target. These are always lower than the ballistics programs estimate. Like in any science, there are therories and then test results.
The largest spread of 6 MOA came from 2 matches at the same range the same year with the same barrel and loads that were shot at -10C to +35C temp differences. Humidity also plays a role. It is mostly air density. I write down all the data I can.
One great thing about good notes on all shots is that it allows one scatch his head and wonder what is happening.
Your 4.25 MOA is still over 40" diff at 1000 yds. And in my experience, hornady has always been "optimistic" with the BC's they give. For that matter probably all manufacturers are. Then we go out and test.
Thanks for the response. It shows you are truly thinking about these things
With our powder shortagesi in Canada I have been sticking with Varget and buying it by the cases when it comes in. when this 40 lbs is used up I might some of the newer extreme powdersI use Litz's bc for amaxs
The Doppler bc hornady published on their eld line are pretty close.
With that much temp swing, even Hodgdon extreme powders will shift velocity some, especially at the extreme temps
