mate......you are asking "one of those questions" like whats the best tyres to run on a ford ranger (answer is round ones,with air in them)
if you already have a similar load your rifle likes.set your seating die using it..because they seat from somewhere along the olgive..your newly loaded round will be similar jump from rifling..if it fits in magazine it SHOULD shoot similar to your old load.
i understand what you meant, i dont have a problem with the current load and length, but recently obtained an O.A.L gauge and tried, found a huge difference in length, over 5mm compared to the book. with such difference prompted to raise the question.Quote:

Aha. The gauge is measuring CBTO, cartridge base to ogive which is well shorter than COL, cartridge overall length.Quote:

A cartridge at that length should easily chamber At, say, 86 mm COAL you could be from 3 to 5 mm off the lands, from checks I have done but with tailoring to the rifle your load should shoot well.Quote:

If your using the hornady OAL gauge, putting a case inside the chamber and pushing the projectiles forward etc you should get a COL longer than 3.210.
The extra length you get is bullet jump to lands and is different for every chambering/rifle. 5mm doesn't sound to much when comparing a light for caliber bullet to a factory chambering.
this is where mine are seated....to mag length for the HOWA1500 they go bang and are boringly accurate..keep the few I have left for wallabies.
my bad, meant to say 3.210'', but somehow the page was on the 6.5 creedmoor for 2.8''. i'd been loading the 270 sst 130 to 3.210''. however pushing the modified brass and bullet all the way in , i got 3.368'', that over 5mm difference.
