Question:
Looking for some opinions

Cartridge is 338'06, bullet is either the 225 grain Interbond @ 2675 fps or the 250 grain Interlock @ 2540 fps.

The game is elk, moose, black bear.

Which would be your choice, and if you care to tell, why?


thanks in advance Smiler

Choices:
225 gr Interbond
250 gr. Interlock

I chose the interlokt bullet. It's bigger and I've got experience with these bullets. I've never had one peel back beyond the cannelure.

I don't see any advantage of the interbond over that. JMO.

Especially in the 338-06 the lighter ,more strongly constructed bullet would be preferable for two reasons:
1. The higher velocity although slight would give a ballistic edge.
2. I will bet dollars to doughnuts the interbond will outpenetrate the interlock.
I would personally look real hard at the 210 grain Nosler Partition or the 210 Barnes triple shock in this size of case.

Read this about SST.

https://forums.accuratereloading.com/eve/forums/a/tp.../454100644#454100644

That 139SST/280rem lost more than half it weight (at 440yds!) on a sheep(Thar) size animal.

For your 338/06 and Bear,Moose,Elk- I would use nothing less than a bonded or TSX type bullet between 210-225gn.

What about this Beauty!;Looks like it will work verywell in the velocity range of the .338/06.

I've shot a fair amount of game with my 35 Whelen ( very similar to your 338/06) and 250gr. Partitions, all with great results on elk and african game. The only time I've gone off the Partitions was for 250 gr Speers and the results were very unsatisfactory at close range. I shoot Hornadys for practice, same POI in my rifle as the Partitions, and I'd have no problems using the Hornady's on deer. For what you have in mind I'd stick with the Partitions or TSX, why scrimp on bullets?

Shoot them both enough to determine which one your rifle likes, it is that simple. There is not a dimes worth of difference in them as far as performance is concerned. wave Good luck and good shooting.

I have shot the 225 interbond in my 338-06 very accurate but I hunt with the 210 TSX.

I shoot a 338 Mag and have used the 250 grain interlock allot and it has never failed. Several friends also shoot the same bullet and they have not had a problem. I have never used the interbond but then when you have had 100% success with a cheaper bullet why change.

I chose the 250gr Hornady only because my .338-06 won't shoot the 225grNAB worth a crap. I haven't hunted it yet, but in test it outpenetrates the NAB w/ a nice muchroom (don't read this ALF). My own personal choice is the 210grNP @ 2750fps. I've shot dozen or so animals w/ this load. From deer to elk & zebra, this bullet finishes nicely out to 300yds+, only ever recovered one & it was a perfect mushroom.

I chose the 225gr Interbond simply because of weight. IMO a 250gr in a 338 is not needed except for dangerous game. I don't consider Black bears to be particular hard to kill or extremely dangerous.

In my 338-06 I have used the 210 NP, TSX and 200gr Hornady SP. I just picked up some 180gr AB to try on deer. I also have some 250gr Grand Slams and Speer 275gr bullets. Mostly to play with.

The only two critters I would use the 250's on would be Coastal Browns or Cape Buffalo. I know in most countries it would be illegal on Buff.

I am leaving for Black bear over bait in a week. I am taking my 338-06 with 200gr Hornady SP.

Like others are saying, I'd choose the 225 over the 250 in a 338-06. The 338-06 just seems to work better with the midweight bullets than the heavies.

Myself, I use 210 Partitions in mine.

But, as mentioned, shoot them and see. You may find your rifle has a preference or a dislike for one or the other.

For elk, moose and black bear the 225g will do just fine in a .338-06. If you want to shoot 250g, that will work fine too.

I would save the 250g for the big bears. 225g is all you really need for the game you mentioned.

But if you like the thought of taking the game you mentioned with a 250g bullet, then knock yourself out.

The rifle Todbartell is asking about is mine. he helped me work up the loads. I don't want to go any lighter then a 225gr (if I wanted to shoot 200gr I'd buy a .30-06 ). and will stick to one of the two bullets listed in the pole. I'm of the "one load" camp.

Balisticaly the 225gr IB has a 2" drop advantage over the 250gr IL @ 300yrds. they both start @ 3500ft.lbs M.E. and both end up with 2200ft.lbs @ 300yrds. both shoot sub MOA. 225gr Innerbonds are $40 a box, the 250 IL's are $29 a box.

the rifle didn't like the 210 partitions.

game is Bear moose primary. have taken a number of each with other calibers, so not worried about either bullet preforming.

Well 2" drop is nothing, energy is the same but I'll bet the 250grIL out penetrates the 225grIB. Sounds like it really comes down to which shoots best in your rifle, but really, don't overlook the 210grNP. It just seems made for this cartridge. beer

210 partitions puked into 4" @ 100 meters, with 53.5 grs. Varget & F210M.

Ouch Tod! If you don't want to give up on the 210grNP, try RL15 (work up to 54gr) or lately I have found H4350 (work up to 62gr) to shoot very nicely out of mine. I could never get Varget to do better than 2moa.

Tod, I've shot 10 of the large african antelope and two elk with the 200gr Barnes X in my 338/06 and they worked great. I'd use the new Barnes TS in 185gr or 210gr if I were you.

I bought a new Ruger 77 .338 W. M. in 1974. It shoots 1 3/4" groups at 200 (two hundred) yards, using the 210 grains Nosler Partition bullet in front of 72.0 grains of IMR 4350. That's hot, cold, sun or snow.

It has put much elk and deer meat in my freezer. Works for me.
