Thread: 270 powder loads?

Hi Dan - I did some load development over the weekend but don't have any good info for you just yet - other than to say IMR 4831 and Reloder 19 are too slow. I didn't have enough 760 to make up enough loads worthwhile for testing, but got some more powder today.
I'm probably going to upset a few people now - but ...... when doing load development, there's a difference between those that shoot to hunt and those that shoot to punch paper. When making a hunting load - you want the projectile to arrive with a degree of accuracy that your prepared to accept (remember - most people are using factory barrels not high spec target barrels) - but unlike shooting paper - you now need the projectile to perform to the best of its design capability. To do this it needs to arrive within the velocity range as per the projectile designers specifications. ie the projectile now has to go to work! I'll use an example I'm familiar with. 100gn Nosler ballistic tip in 25 cal. In this example the load had a muzzle vel of 3150fps. If I shot an animal inside 25yds it drilled a small hole every time -(unless it hit substantial bone) The bullet was useless. Outside 25yds and to at least 352yds it did major damage - the projectile behaved as it was intended by the designer because it was operating within the designed velocity range. Now I don't know enough about the 150gn SST because i haven't shot enough of them yet - but why reinvent the wheel when a bloke who is dedicating his time to researching projectiles says - for the 270 anneal the 150gn SST projectile as per the video clip and keep the muzzle velocity high. I for one will be following his recommendation - gives me more time to do other things. And in case anyone is interested - a candle flame is hot enough for the anneal process he's doing. I looked into it because I didn't believe it either.

Flame temprature is irrelevant, a static spark from taking off your jersey is over 8000 degrees c but wont weld fuck all or even burn your finger because the total energy output is sweet fuck all like....like...like well a candle.

yer i melted some tips trying to do it with a candle

Thanks Kurlyman, look forward to hearing how you go. I'm to inexperienced to delve into the projectile argument but everyone's points are valid, let's keep it civil.

Cheers
