I think your missing my point! And don't take this wrong way!! Now read this slowly and think about what I'm saying here.
Take a 212 ELD-X load it to mag length or 3.600" COAL it will fit in a factory ultra mag box with a little room to spare.
Now take a 225 ELD-m and do the same thing, same length COAL the base to tip AKA>>>Cartridge Over All Length will be identical 3.600" 212elx is 3.600" 225eldm is 3.600" 230 berger HT is 3.600" 200 accubonds is 3.600" 210vldh etc. They all can be loaded to factory mag box length or 3.600"" on the nose !!!!!.
Will the ogive start in a different spot on each bullet? YES
Will the nose of bullet to ogive start distance short or long dictate how far away from lands each bullet engages at? YES!
I know all about that, but that's not my point!!
My point is, if you have a factory rifle (like the OP does) and do not want to do any mag work or alterations, you do not need to seat any of these bullets clear out to the lands and have a single shot to get them to shoot as others have posted on here with good success it just takes a little more finesse!!
I've shot hundreds of rounds out of a factory 300 rum sendero's with hand loaded 230 berger hybrid targets seated to fit the factory mag box and got them to shoot dam good and i know a lot of others that have done the same thing! For hornady to publish such an over exaggerated COAL of 3.900" when that leaves you single feeding your rounds in an abomination factory chamber or in most case scenarios you have a SAMMI length factory chambered rifle, this leaves you with a headache before you even start because A. they wont even begin to go in the rifle
B. you didn't check the length with modified case length gauge before loading the rounds basically hoping their info is correct! that's just stupid on hornady's part and the hand loaders part by not checking first, then for the same cartridge turn around and tell you a way shorter length with heavy and longer bullets???? ZORACK you even stated that your rifles chamber wouldn't even handle that over exaggerated length.. that's not a red flag to say why do all these others say so short but yet this one is so freaking long and yet wont even go in my rifle???!!!!!! They are providing a load spec to individuals that more than likely have a factory rifle and are expecting it to work and have guys obviously loading them to that length and having them not even come close to working, that just simply blows my mind!
