Do these perform well at 7mm Rem Mag velocities? Target species will be moose and black bear, possibly white tail and caribou as well. Any load recommendations? Other bullet recommendations are welcome as well, the local guys only stock Hornady though so it is the most convenient.

As a rule of thumb, I never load plastic-tipped bullets over 3000. I understand that they're built a lot better these days; I suppose I haven't quite caught up with the times.

From what I hear, the IB's are quite sturdy, and you should have no problems
 
you're 26 years old, what era do you live in :eek: :p

Id rather load a 154 IB in a 7mm Rem Mag, take advantage of the case capacity to drive a high BC bullet to good speeds.

A 139 should be able to do 3200 fps or more in a 24-26" tube, and a 154 grainer to 3100 fps or a tad more.

154 retains more downrange velocity and energy, drifts less in the wind.

139 grain would be better suited to a 7-08 or a 7x57, 284 Win, 280 Rem etc. Not that it cant work, but its not as ideal, IMO, especially for moose/bear

If you are referring to me here, you skipped a decade TB. I admit, though I haven't got a clue what I'm doing with this new rifle. I read a few threads where Gatehouse and others were getting good results with 140's in this chambering, so I figured it was a good starting point. I'm open to suggestions, enlighten me.:)

Edit: 24" bbl, 1 in 10 twist.​

reffering to Prosper, the old man :D

anyways, a Triple Shock X bullet will penetrate much deeper than a 139 interbond, so it makes it more suitable for elk moose bear etc.

Wel, the H IB is a good bullet...

Bit dont' ask it to perform ike an X bullet;)


The 154IB has perfromed well on elk for 2 of mybuddies in the 7RM. If you are targeting moose, then I would go for the 154 or heavier in the IB.

I am loading the 140gr TSX with my 7RM, but that is truey the equivilant of thw 160gr Nosler Partition.`

if I was to use a conventional cup and core bulet in a 7RM, I woud be looking at alot heavier than 140:p
 
Hornady makes 162gr. &175gr. Interlocks that would be fine for heavier game. Should give you the results you're looking for.

Don't discount the Interlocks, they can be very accurate bullets. I loaded some 139's last week and my first load yielded several 5-shot groups 1 moa or less @ 150 yds. in my Remington Sendero using a 10x Bushnell Elite 3200.
 
Actually Gatehouse, I was thinking of the 300WSM vs 303Brit thread where you mentioned you were shooting 140 accu-bonds, which is a cup and core type bullet isn't it? Very similar to the interbond in construction I think, I may be wrong. No matter, I can step up to a heavier bullet like the 154 or bigger. You guys know more about this than me. Any powder recommendations for the 154's?

The AB and IB are bonded cup and core bullets.:)

I htink (never shot anyhting wiht a interbond) that a 140gr IB will kill the hell out of a moose, 99% of the time, but if that is what you are targeting, then why not step up a bit in weight to make it 100%?;)

Any powder that works good for the 7RM will work well, I am sure. When i load for the 7RM, the first powders I reach for are- IMR 7828, RL 22 and H4831

There are orthers that will work, of course, but these have always worked 100% for me, with bullets from 140-175gr, Hornady Interlocks, Nosler Partiitons, X bullets, TSX, GRand Slam, Accubonds, Ballistic Tips nd gawd knows what else.:)
 
The Interbond at high velocitys (such as the 139g or even 154g at max loads) will open very wide and hold a large mushroom, this limits penetration.

I think that the 139g is a wicked deer bullet at those velocitys but may not be quite a deep enough penetrator for moose. For sure it will work but it may not always make it to the far side of big animals.

The 154g Interbond is a deer bullet at 7mag velocitys in my books, not the best choice for moose but still a better choice than the 139g if you want to shoot moose.



The Accubond and Interbond differ in thier intended performance. The Acubond is designed to peel back about a little less than half way (ligher weight peel back further) then expansion stops. The jacket folds against the shank, the result is a smaller mushroom and more shank left on the bullet = deeper penetration.

The Interbond is designed to keep peeling back, the jacket does not limit expansion. It will peel back all the way down to the base of the bullet at high velocitys. The jacket also keeps the shape of a wide mushroom (does NOT fold back against the shank) the result is a wide bullet with no shank left. This pancake shape does not penetrate as deep but makes a bigger wound channel.

Said I was old fashioned, not old ;) Still, bonded core plastic tips are still fairly new on the scene

Listen to T.B. 154gr for moose will give you a lot better result:D.​

what an awesome load for anything in North America, out to any sane range

hard to beat a properly loaded 7mm Rem Mag. wicked downrange numbers with moderate recoil. :cool:

I shoot a Tikka 7mm mag and have loaded quite a few bullets. I have had great results using 150gr Sierra's, 150gr Nosler Ballistic tips (great accuracy, crppy for hunting) 140 gr Nosler Accubonds and now I am using 160 gr Accubonds. I have tried RL22, IMR 7828, RL19 and I have found that my rifle likes IMR 4350 the best. It may not be the ideal "recommended" powder but I have loaded the 140's with 62.0 grains of IMR 4350 and a ave. chrony'd velocity of 3063fps. Yes other powders will move the 140 faster but the deer really doesn't care. I am currently loading the 160 with 60 grains of IMR 4350 and have a ave chrony'd velocity of 2900 fps. It is real accurate.
