Thread: reloading 308 win

If you are going to be on eTGTs 45grain behind a HBC might not register at 1000yds, 45.5gr should every time, again depending on the gun, case.

Perhaps I am on something also, but WTF does "eTGTs behind a HBC" mean in English, can someone translate this code for me please.

Probably not going to be shooting Fclass with a m77 but I have been wrong before.

Sorry, etgts = electronic targets. The ones in New Zealand from Silver mountain targets only work with a projectile that is still supersonic. HBC is one of several 308w 155gr match grade HPBT's used. It has a secant ogive I think making its seating depth picky but its slippery. So to be still Supersonic at 1000yds you want about 1250fps, if using a HBC projectile 45.5gr of ADI 2208 is about right. The Nossler match with the same load will have dropped about 120fps+ so usually fails to register.

30 caliber 168gr AMAX will not be supersede by the ELD range. This is directly from Hornady and confirmed by Reloaders, it is too popular in the USA to discontinue.
Propably just low stock at the moment, try Hunting and Fishing North Shore, talk to Hennie he will see you right.

My bad I thought the entire range of amax had been superseded

Yeh me too, the entire range but that one and maybe 1 or 2 others will be replaced.

Speed of sound is about 1120 fps at sea level.

I shoot a 155gr Lapua Scenar with 44.5gr 2208 in Lapua Palma cases through a 32" 1:10 True-Flite barrel at 2840 fps.
The projectile's still supersonic at 1000 yards and registers on electronic targets.

I've also shot a 80gr Amax projectiles from a Savage 223 that still are supersonic at 1000 yards and register on e-targets.

From experience of our etgts at Trentham anything less then 1200fps is unreliable. So same load of 45.5gr of 2208 with nosslers the ones that registered had about 1170fps maybe 2 out of 5 or 6 (sat there did that) 45gr behind a Nossler will not register at all. Generally HBC and the Lapua seem very comparable in terms of BC showing 100fps more than nosslers from what I can see, 45.5gr of 2208 for them seems 100% reliable, this is probably gun dependant, the last barrel it had wouldnt register at all at 1000yds we had to bin it.
