Long range shooting

[iron cat]

I agree with you RJ. The scope was part of PAUL REBINs (SP) estate sale, I'm pretty sure he knew what he was doing. I've got 2 of his rifles a CG 63 6.5x55 Mauser, and a semi custom 10/22 Ruger. Both are outstanding rifles, a friend of mine who introduced me to him has one of his rifles that he used in his Swiss competition shoots.

Paul and his buddies like George Farquarson and Clint Dalhstrom ( to name a couple of old guys) had certainly "sent
a few rounds downrange" at 900 and 1K in 15 shot strings , in their time!

yes they did, our mutual friend and I sold off alot of his equipment and stock. He was a guy like F1 car designer Adrian Newey , it's like the can see the atmosphere and it's whorls and loops

For 300 y or m a .223/5.56 will be fine. Longer bullets need a tighter twist barrel… I forget the formula. Be aware, though, that if going with .223, the longer ranges need longer bullets in most places (and spinny rifling). At sea level a 62 grain bullet drops below supersonic at about 700 m, and then you have no good idea where the bullet is going. That’s why (one of the reasons, anyway) fb tr stayed with .308 back in the 90s when countries were switching to 5.56… the issued ammo (which was a thing back then) wouldn’t reach the long ranges (with any accuracy) unless you were at someplace with thinner air, like the ranges in the mountains over 1000 m elevation.

The OP already bought a rifle , in 6.5Creedmoor I believe.
As far as the .223 goes these days, a 1:9 is twist is very common , and 69 grain bullets will make the trip to 1K easily, although if shooting factory ammo, both the 308 and 6.5 Creedmoor have much more choices for factory stuff.

I think I saw that he'd bought a rifle. My TR is 1:9 - yes, handloaded 69 gr reach 900m (essentially 1000 y), but in the early 1990s the government hadn't cut off supplying IVI ammo to DCRA and provincial affiliates. My rifle was built for the IVI stuff, but it turned out that issued military ammo with 62 gr penetrator tip projectiles would wander after about 700m at "normal" elevations. Won a match at Heritage Range in the mountains outside Calgary (3, 6, 900m) but at Dundurn, the 1000 yd shots were all over the place. Until I went back to .308 or shot 69gr from the 5.56.

The Savage my son now owns was set up for the 69 grain Match Kings back when the DCRA was still supplying IVI and so is my Musgrave (originally 7.62 but rebarreled to .5.56 with a 1:9 Krieger )
However I just shoot them for fun.
When I get "TR serious" I shoot a 1:6.5 twist Krieger that was barreled up by Bill Wylde with the 600 action 'smithed by Jim Dugan.
It shoots the big 95's right out there as long as the nut behind the bolt reads the wind properly
I rarely shoot a 308 prone anymore mostly for 300 meter offhand shooting , the danged things just beat my ol' body up too much.
