Cup and cores

I couldnt get partitions to group as well as the factory winchester grey box i fired off to get the brass. Not bad but i thought i could do better
Woodlieghs and sst both beat the partition accuracy wise
However my buddy wants to put a couple hundred rounds thru to get used to the gun.

I really liked how the partitions shot. If I can't find anything else that shots this good I'll go back to em but they outdid my 130gr ballistic tip load.

I have been loading and shooting Partitions for several decades, and I am very fond of the way they work.
That does not stop me from trying other bullets of premium lineage. [A-Frames, Weldcores, Accubonds, Scirocco IIs, etc, etc]
I even take some C&C bullets hunting on occasion. But the cost of Partitions does not deter me at all.
I judge all other bullets by them, and some have disappointed, some are great. Dave.
 
I don't use them in a 300 mag myself but I do shoot them in many other cartridges. One of my favorite cheap bullets is the 180 grain Winchester Power Point launched at around 2500-2800 fps performance hasn't disappointed. Never tried to drive it faster since other than my 7mm mag all my cartridges are based off the .30-06 case or smaller.
Partitions do seem high as far as price goes until you remember they're balancing two cores so need higher tolerances for predictable repeatable performance. It helps that they are the standard against which others are held. I have no problem with Accubonds, NBT's or more traditional cup and core bullets in most of my cartridges.

The Partition is the bullet that everything is compared to right?

So let's compare. The Partition typically expands close to double and loses between 1/3 and 1/2 of its weight unless impact velocity is way down. Apparently that's the gold standard. It is a very good compromise, and comes with an insurance policy.

A decent cup and core on the other hand expands to about double, and loses between 1/3 and 1/2 of its weight unless the impact velocity is way down. It's a great compromise, just doesn't have an insurance policy.

The difference is that you can count on natures most perfect bullet (says everyone) doing that every time while the lowly cup and core will only do it most of the time.
 
While partitions are my favorite bullet, when I got my 300wm there was a deal on a close out. I bought 6 boxes of Remington Core lokt ultras. Really i bought them for the brass, still working on those. They have been excellent.

Have a bunch of 180 partions I like in the 30-06, and either those or 200 gr partitions or accubonds will be the first bullets tried in the 300wm.

I personally think pushing really large projectile in magnums defeats the purpose. Since I have a lot of choices I just reach for the next more powerful caliber. The 240 weldcores sound like 338wm loads. Why not just shoot a 338wm.

My exception to this has been carrying a couple of stompers. Heavy bullets in case of a visitor when I'm elbow deep field dressing. Example was a 235gr load for general purpose for my 375 rum, with 300gr partitions for short range thumpers.

Brybenn, and others,

The SST is a cup and core bullet. Have you tried it on game?

I have comer into a bunch of them, 154 gr .284 dia. Wondering how they hold together.?

I havent used them on edible game. Ive shot coyotes with them in my 2506. Theres no agrument the coyote is dead. Firing them thru a 2x4 and into water jugs it blows the back end of the 2x4 apart and the first 4l water jug is shredded plastic and whats left of the front half is wrapped tightly around the shank. Both 117gr 257 and 180gr 308. More weight left percentage wise with the 308 diameter. I chose them for hunting new clear cuts for bear. Shots can now be 300 yards and i wanted a violent bullet for lung and heart shots. The sst is a faster expanding interlock essentially. Perfect deer bullets. I wouldnt try to break down a bear or mooses shoulder with them but a deer wouldnt be able to walk it off.
They are very accuate bullets. If you want to liquify the animals lungs theyre great. Whereas when i shoot the 180gr woodlieghs thru a 2x4 and into water jugs it drills a clean hole thru the wood. Tiny entrance hole in the first 4l jug and 1.5" exit straight thru the 3rd jug with thebullet coming to rest in the 5th jug as a picture perfect expended bullet. I chose them for breaking thru shoulders.
 
If under 2800fps i think youll be surprised how they do. Like mentioned before a heavy bone will make a mess but im sure theyll punch thru a deers shoulder no problem
 
Woodleigh 30 caliber 240gr PP SN expand like this. Should be a decent general purpose bullet for NA game in my 300 WM at 2700 fps muzzle speed. Probably will lose a bit more weight at close range compared to longer ranges. Used their 35 caliber 310gr RN SN in my 358 Winchester which at close range shot clear through broadside on Moose. Good bonded core bullets.

This is a sincere question...because I'm not a hunter, I have no experience in this area. When you go hunting, do you carry both rounds and load the one most appropriate for the task at hand? For example, "I've got a clear shot at the lungs so I'm going to put an SST in the chamber"...or "looks like I need to break some bone if I am going to harvest this animal so in goes the Woodliegh"?

Generally, no. Pick one bullet, take that hunting. The problem with having multiple projectiles on hand is unless they shoot to the same point, at the same speed, with comparable BCs, you need to know which one your scope is set to and how far off it'll be with the other load. For me, that's too much to think about. I want one good load where I know it's trajectory and I don't have to worry about putting the wrong ammo in or forgetting to adjust my Kentucky windage ect.
 
I think relegating bullets to C&C and premium is silly.

What is useful is reporting that certain bullets are prone to failure - like the early version of the Ballistic Tip or Barnes X.

A good C&C is a good bullet. A premium mono that sometimes pencils through is a poor bullet.

Whenever I find myself thinking about bullet choice (and I have a shelf full of choices) I remember my grandfather, who homesteaded near Smithers in 1914. He shot 52 moose (and those BC moose are not the little ones). Only 1 required a second shot. Not because the bullet failed but because his shot placement was off.

He had a Winchester 94 rifle in 30-30 and shot garden variety cup and core bullets. He told me that the key was a rifle properly sighted in and not getting too excited while taking the shot. In other words "shot placement".

I am guessing he waited until he got the shooting angle he wanted for a good shot and that if he had used a 30-06 with a good 200 gn bullet he would have had more "good" angles to consider.

Gramps shot his moose behind the ear. DRT

No, you pick the bullet you expect to need, and then regulate your shots. If you have a frangible deer bullet and all you are presented with is a end to end shot on a moose, you wait until the moose presents himself properly or you don't take the shot. If you are loaded with deep penetrating bullets, you just take any shot you want, assuming you have a clear path the the vitals.

Now how are we going to have a nice emotional discussion if you're going to bring logic into it?

SST are known for their violent expansion and large exit wounds. Hit a larger bone, and it's a mess....like the shoulder joint. Good frangible bullet for long range, fine with meat saver broadside double lung. Quartering or very close, depends on the placement I suppose.

I know I have said it before, but I'll say it again; anneal the top half of the SST in a candle flame and it reduces the frangibility of the projectile while preserving the ready expansion. The bullet will tend to stay together better, as the softer forward jacket peels back (rather than fragmenting) and hence penetration will generally be deeper. This does not necessarily benefit all SSTs - generally the longer, heavy for caliber SSTs like the 150gr. .277" and the 162gr. .284". I got this info from Nathan's Foster's site and so far the results with 150gr. .277" SSTs confirm his findings.

I bring other rifles when i bear hunt. If i have bears hitting baits or feeding in open clear cuts ill use the sst which my gun is sighted in for. If im planning to hunt where i need to anchor a bear ill switch to the harder woodlieghs. I know exactly how many clicks my scope takes to zero my load at 100 yards. However if im planning a close shot my 300wm generally stays in the truck and i bring a 458wm or 4570.
My scope is repeatable and ive shot the sst loads out to 700 yards and can keep all shots on a 18" metal cooler. I havent shot the woodlieghs passed 100 yards yet but its 9 clicks right to zero the woodleighs. 9 clicks left and its still dead on for my sst
I hunt in often times extremely thick bush so i like to drop a bear in its tracks where its easier to get at instead of following it into the dark abyss
