Is there just not the good bc bullets available or it cant push them fast enough?

From our comparisons with electronic target data (velocities at target) a 308 is 100-200 fps faster at the target than our 223 at all distances (if I recall correctly). But the data is only valid for comparisons on the same target on the same day.

I - now - think our 223 with our maximum safe load will still be supersonic at 1000 yards.

While we haven't shot in windy Trentham conditions we have shot at very, very windy Ashburton conditions (even the experienced shooters agreed the windiest in a long time) but not at 1000 yards. My son was competitive even in the strongest wind.
We'll just have to wait to see what happens at the nationals.

Interesting point VC, Amax 80gr is G7 0.231 compared to Scenar or HBC Dyer at 0.236

My head says you could well be correct, but my heart kinda goes "not so sure"

25% saving on projectile cost and half the powder, going to be interesting to see how this pans out...

There is also a 90gr round, I did some casual reading last night and really the amount of effort spent on the 223 to make it work and get the results it does is astounding, the wind though is ugly. I am not sure that the USA ranges get such variable wind as us?

This was interesting and about the best piece I found,

Who all is shooting a .223 long range? - Page 2

The cheaper shooting is a big plus given how things seem to be going. Im quite tempted to try an AR15 at 600yds and less for the hell of it. Might cause a few heart attacks at Trentham though, "oh my god its a black thing that self ejects cases!!!!!" what the hell I like stirring complacent ppl.

@Cyclops, with a 308w, 30inch barrel, lapua match case, Fed 210M, HBC 155gr projectile and 45gr2208 is just enough supersonic to register every time at the E-target. So if you are clocking 1200~1250fps should be OK. I have some e-targets around here somewhere.....

@steven we've successfully shot e-targets at 900 yards, yet to do so at 1000 yards.

Manual targets at 1000 yards require alert markers as the 80g Amax don't hit hard or leave large holes.

she was sitting next to me at prizegiving.

big table with lots of goodies, you got to go up in the order you finished and pick what was left, i told her right at the start, if nobody else gets the cake Im grabbing it

if they keep handing out baked goods as prizes I might start taking this shooting lark a lot more seriously, hehe....

Ivan, forgot what username you use on here, can you pls PM me.

old thread i know nice job you did there ive just bought a project omark myself what kind of bipod is that
