Project .223 1 mile Part #1

There was another offered at SHOT this year that uses a turn wheel so the range is variable. Might be easier to find your zeros.

There are various forms of this concept. As long as they track true, they work. I came up with a design a decade ago and got over 200mins of travel.

Worked great for those silly over 2000yds shots.

With scopes that have the travel you suggest, these mounts aren't really necessary. we can easily shim the base and rings to get well over 1000yds zero at full down on the scope. Now we dial up to cover the remaining 1760yds.

as a rule of thumb, the elevation you need to get out to 1000yds is used for the next 500yds. That amount is then used for the next 250yds.

So... ball park SWAG, 1000yds is 35 mins. 1500yds is 70mins. 1750yds is 110mins.

JBM and other ballistics programs will give a better idea but the key is whether that bullet will go subsonic.

Send some down range and let us know if they hit or tumble.

Looks like you need to check your pin protrusion and replace your spring with a new extra power one, it will get rid of the cratering that you had to start.
 
Went out today to do some load work with the 6.5 Creedmoor,

Here are the first 6 shots out of the 223 at 600 yards

I colored the impact points with a marker so they would be easier to see

 
Great post! Any trick for keeping the powder in the brass with no projectile seated? Do you just have to be super careful? I am thinking about using earplugs in the necks?
 
No, it is not sarcasm. This was a great post! it motivated me to get off the computer and go purchase a "Lee hand press" so I can save on component costs as well. You can see in the original post that Clayne_b has primed his brass and filled it with powder, but did not seat any bullets. He was able to have all charge weights of powder on hand but only seat the bullets into the ones that his ladder/group testing indicated were worth testing as per the nodes and then groups. So all in all out of 100 primed and powder filled cases he only actually seated bullets in 37 of them. My question was how did he transport 100 powder filled cases from his home to his shooting location? Either he shoots very close to home and or is very careful to transport the full cases without dumping the powder out of them while driving to the range. Maybe he even has a simple trick (my wild guess is sticking ear plugs in the case mouths so no powder spills out on the bumpy drive to the range.) Maybe he has a neat trick that I can learn from him or another shooter that will allow me to replicate the transport of primed, charged cases with no bullet seated? Personally once I hit the dirt roads my jeep cherokee morphs into a poor mans baja truck and powder would be everywhere but in the brass..... That last part might have had a hint of sarcasm :) But if there is a trick to it I would love to hear it.
 
No trick, 1.5 mile of dirt road and 3 miles of pavement to get to where I shoot. I put it in my shooting gear bag in the bottom and stacked everything in tight around it and drove carefully
 
Spenom, it's not uncommon for schuetzen shooters to transport pre-weighed charges in vials with corks. That is done so you can pre-weigh charges at home and shoot with just one piece of brass. You can find sources for small corks on line.

Very nice work

Well documented, full of pictures and explanations.

Much appreciated.

Now, let us bring some Zombies just for fun.


Have a nice Zombie Day.
