    160 gn partition would be my 1st choice out of 7mmRM for big stuff, & for the ranges you’ve stated. Bonded pills like 160Abs or 150gn Swift Scirocco would also be pretty useful

    Woodleighs, if they are really big Deer

    Accubonds or the like for Red deers as a all round bush to yonder..


    Big Deers with dense Bone is where issues crop up from, at closer than moderate ranges the velocity from magnums is too high and thus needing some Bonding to ensure penetration of some bits or pices of the projie..

    So many options but alot of $$ between ..... ELDX seem alright for a cup an core sleek bullet thingy! im not 'confident' for it being an all round projie and will be sure to place a shot on stags under 200 for sure.. placement as mentioned above is the key.

    Looks like the Partitions and the Accubonds are fairly popular so might start with a few of them, thanks very much fellas and again many thanks

    Aslo the Speer hotcore and trophy bonded bear claw, I'm in Canada, the Partion is the standard, by which all others are judged,
    I like Partion/Accubonds 160 gr in my 7mm's, swift 150gr if I want a bit flatter.
    I have 3 boxes of 154 gr interbonds, and thus far with my 7x57R I've got a couple bear's, a few deer and a cow elk, no problem.
    and of Corse, there is always Barns TSX/TTSX, if you want heaps of peneration,

    Although I have never used Partitions, I have never liked Noslers idea that it is ok for the front to fall off. Weight retention, penetration and a good mushroom is where it is at for me.
    The Hornady Interbonds I've recovered from a 3006 have usually retained around 90%. I've only used Accubonds in a 7mmwsm and have yet to recover one. They have all blown right through but done the job.
    Overkill is still dead.

    Not new and trendy but Partitions are the business for your application.

    If primarily shooting large wild cattle i'd prob look to step up to a 300WM or similar running a heavier projectile.

    If the deer are that big Barnes must be at the head of the queue.

    thats a contradiction if ever Ive seen one......partitions were designed so you get best of both worlds...and have with very few exceptions been doing it perfectly well ever since...BY DESIGN the front half is fast opening to create maximum trauma...the rear half holding together to give you the penertration/weight retention.....if they got all trendy the rear could be solid copper....but why mess with something that works so well??? to some extent it is about using correct bullet weight/design for task at hand.... well actually its very much about it.... thats why I shot last bull with .45/70 in back of head/neck then pithing spot .....rather than using 308 and doing so twice as had dome 2 weeks before......in theory the 180grn rn SHOULDVE BEEN HEAPS ENOUGH.....but in practice,not so much...was too soft and had opened too quick...a FMJ wouldve worked better...but he 400grn cast jobbie at pedestrian speed from 45/70 just had far more authority.

    Perhaps I didn't explain my reasoning very well. The front half of a partition is a very basic but shallow cup and core. They may well open up fast, but the core also separates realatively easily too. Nosler stated the partition ensured the rear part of the core was retained to retain weight. Bonded projectiles generally retain more weight than Partitions.
    RWS had a projectile called H Mantel which was a similar concept.

    Partiton's have changed over the years, originals were made by drilling out solid rod, then from tube, and finialy swaging
    I've never had one break, and I've got a mate with a coffee cup of them, all nicely mushroomed, taken out of bison, moose, bears and elk,

    Nosler has this to say.

    When word got out that the old Partition was being phased out, a buying frenzy spread rapidly throughout the hunting world. After all, some suggested, there was no way the new bullet could be as good as the old one. Adding to the panic was Noslerís decision to delay production of the larger calibers; it was not long before some hunters who had rifles in .375 H&H Mag. were willing to pay $5 each for 300-gr. Partitions. There were minor production issues early on, but once they were history the new bullet proved to be a big improvement over the old bullet, and it mostly had to do with differences in the grain structures of the two jacket materials being used. In addition to being harder, the grain of the old material ran at right angles to the axis of the bullet, and that encouraged the wall of the front cavity to shear off when expansion reached the partition. When that happened, none of the front lead core was retained. In addition to being softer and more ductile, the grain structure of the new material ran parallel to the axis of the bullet, and that enabled it to curl back against the partition without shearing off. The result was a larger frontal diameter along with higher retained weight due to partial retention of the front core.

    You are correct @7mmwsm, the bonded pills will retain more weight than Partitions. But the terminal performance of Partitions on the target species & range stated by the OP, “large deer, 50 - 450 yards” is superior in my experience to the ABs.....due to the fact that the front end is more fragmentary creating much larger wound channel and trauma, especially as the range stretches out. While the bc of the partitions is pretty pedestrian it should still be north of 2000fps out of a rem mag at 450 yards.
    However if the prime target was big beef bulls up close then I’d go bonded.

    I'd use the 175gr nosler partion.
