HHhuntitall, What is your take on 285 Gr. Hornadys? BIG's . 338/378 has a 1-10" twist.
An exposed lead tip burns off at high velocity and/or gets mutilated in the magazine from recoil. A Poly tipped bullet such as an Accubond or a Boat Tail Hollow Point will have superior flight characteristics.
The Accubond has a core that is soldiered to the jacket.
Berger advertises their original match bullets as hunting bullets because they come apart inside the game and the VLD's shoot FLAT! They are kind a picky in some rifles. They are also very long and may not feed through the magazine in some applications.
Just talking, here! I have the 190 Gr. Sierra Match Kings loaded in the . 30/338(the little one
). They are absolutely fantastic for accuracy. The 185 Gr. Berger VLD's fit my magazine but the batch I have are undersize at the pressure ring. Micrometer reading of . 3075" does nothing for accuracy on a . 308 Groove diameter barrel, at long range. They still cut 12" or more off the trajectory at 600 yards with a 400 yard zero!

Berger has a 300 Gr. Tactical bullet that could be a "Projo" for BIG's Cannern:-laf
Dont know what the terminal result would be, on an Elk! DRT is the goal!

I've seen a lot of problems from the Poly tips. A few years ago, David Tubb offered a poly tip matched bullet in 111gr . 243. He quit it when they couldn't keep the quality control. Lot to lot varies so much with those, they tend to not be use by match shooters. I used several of the A-max bullets a few years ago, but I had to start over on reloads ever time I got a new lot number, and some lots just plain sucked. When you go from a 1. 5-2" group at 600 to a 9-12" group at 600, something is wrong. And I still have over 400 of those Obamanations in my reloading closet..... #@$%! The BoatTail Hollow Points tend to shoot a little better, but I still have a bad taste in my mouth..... I went through this with the 750gr Amax a few years ago, too, so I'm not gonna wait for them to do it again.....
Now, as for the lead tips burning off, that's not true. However, if they are terribly marred from recoil in the magazine, they will fly off and throw the bullet out of concentricity. Sierra/David Tubb, Hornady, Bryan Litz, Savage Arms, US DOD, and soooo many others have extensive slow-motion films studying bullets in action on targets of various material, including ballistic gelatin, apples, water, and wet, shredded newspaper. Polymer tips are safer in the mag, and work great to get the minimal penetration needed on light game before the jacket begins to peel back and the bullet expands. Lead tips work the same way, and have worked that way for over a century, but damage in the magazine is a consideration on a high recoil rifle, as your second round may not shoot as accurately as you want/need. Velocity is another factor affecting both polymer and lead tips. Both can be off center and cause innacuracy, but Polymer tips tend to be more vulnerable to inconsistencies in molding.
The Accubonds. I have limited expereince with the Accubonds. I've shot a few hundred 140gr in a . 270 Winchester I have and quite a few 180's in my Cousin's 300 WSM..... the . 30 cal shows me the most promise, as the lighter bullet is travleing at so much faster velocity, and really has the "slaughtered" affect on hogs... I like it. Dead is dead, but that thing really knocks 'em down. Even with poor placed shots... . my limited experience on large game makes me hesitant to reccommend them to BIG. I did get a flyer from Nosler introducing their new 300gr Accubond in . 338..... I haven't gotten my hands on a box yet, but I will. And boxes of 50!?!? WTH?!?!? C'mon, do you guys not make more than that at a time!?!?? And the price sucks, too..... but the Partition bullets work well, so I pay the price when I need 'em. I have found that many rifles are finicky with Nosler bullets. Some won't shoot them satisfactorily, while some will take them very well... .
Every rifle is different. I had at one time, two rifles, both . 223s with barrels cut out of the same piece of stock, made side by side, chambered with the same reamer, the same day, side by side. Both were in McMillan stocks, NightForce scopes, etc. One would shoot 4" groups at 1,000yds, currently holding the NRA 600yd Civilian FTR record, and the other shot 8" groups, regardless of load or bullet... . Every rifle is different, regardless of how much care is taken to make them the same. The many variances in material, labor, and evironmental parameters is evident.....
