List of "shorter" 7mm 150gr bullets to load 284 win (std short action 2.800)

I found some core lokts. I personallly haven't used them before. Other guys I see: core lokts are pretty standard medicine for big whitetail and black bear where we hunt.

I reload to save $$$. 284 is like 60 bucks a box!
 
Caught your post a bit late. I load the .280 Rem in a K98K mauser action, so my COL is limited to less than the SAAMI max. This rules out many "long" bullets for me. I am a big fan of the Speer Hot Core. They are deer hammers so long as you keep the velocity reasonable. I like them better than the Rem Core Lokt. Other bullets that are relatively short in 7mm/150 gr are the Nosler Partition, Hornady flat based interlock 154, Win Power point, and the Speer Grand Slam 145. The latter is my go-to in the .280 on whitetailed deer at higher velocities. I believe the Norma Oryx is also "short," but I have no personal experience.
 
I really wanted to run the nosler partition 150, but for the price I would like to sample one first
Sooooo.... In case nobody has mentioned them yet, 140 gr Sierra pro Hunter! Also kick up to a 160 hot Cor and no worries about shooting something too close.
Eta I know in your op you said no 140s, but that's really a good deer weight in a 7mm, 150s are cool too, but 140-160 is right about where the .284 thrives on deer.
Comparing the 7 140s to a 6.5 or .277 140 is like comparing 150 7s with 150 277s and 30 150s, they're not the same duck. However if you're dead set on staying heavier than 140s, consider the 160s too.

98s what gun are you loading for? What powder? Why the hang up on 2.800 COL? Is it a chamber or mag issue? Is the bullet hitting the lands? Does the shape of the bullet make a difference? Just trying to understand.

If he's cramming them in a true short action, he's stuck with the 2.8.....

It's a Browning A-Bolt. I'm stuck with 2.800" I could mod the mag box for MAYBE another 0.030" but is it worth it, I think no. Besides, if the gun shoots short flat base bullets better than longer boat tails this leads me to believe the twist rate won't like a LR (long range) type bullet like an accusing or something (which will intrude on powder space)

I compare this 284 win to 308 and a 270 for people who are unfamiliar with it. It's got similar trajectory to a 270, but can shoot heavier bullets similar to a 308...... without as much recoil as the 308.

I bought the gun because I'm not a big dude and short action rifle fits me better. This 284 win cartridge on the heavy bullet heavy load side is as much recoil as I want to put up with. I size my guns to me, how much recoil I can take, and the most performance I can possibly get among other criteria. I'm a picky guy!

I like the heavier bullets too cuz I may come across a black bear on same hunt......I really just need one load to do it all for my scope rifle, and one load to do it all for my open sight lever.......not too much to ask for hahah
 
What bullets have to shot in 284. I remember posting to you before.

I've shot:
Factory win super-x 150gr
Speer 145gr BTSP (these were running slower but shot approx 12" left and 12" low @ 300yds)
Sierra 150gr gameking #1913 (was hoping this was THE bullet) but 0.5gr powder change was changing point of impact 1.5" per increase. I didn't like that. That was at 150 yds.

The guns new to me, I don't have much trigger time with it at all. Only a few handfuls of rounds. 2 seperate shooting sessions is all.
 
I measure

SPEER
145 BTSP #1628 1.160"
160 BTSP #1634. 1.250" (too long imo intrudes powder space)

SIERRA
150 GAMEKING 1.090" (It must have been I think it was shorter than the Speer 145 not 1.190")

Unknown bullet Speer Grand Slam or Federal Fusion 160gr 1.265"
 
I just look up case dimensions, from rim to bottom of neck is 1.885"

So 2.800"-1.885"= 0.915"

A bullet that is 0.915" or shorter will not intrude ANY case space loaded to 2.800" COAL.



Rim to bottom of taper below neck is 1.774" so 2.800" -1.774"= 1.026"

That being said I feel a bullet 1.030" and shorter is best suited for this cartridge in short action. Does it matter real world if bullet takes up more case space than that???? That I will determine (to some extent)
 
I'll have to go back and see but I'm pretty sure that sierra #1913 150gr GK is 1.090" that's why it seemed like such a good choice. Idk if the problem in vertical shift in impact due to powder charge weights changing by 0.5 grains should rule the bullet out or if it could be a powder issue????

I will test this bullet more.

Your thoughts?
 
Looks like the Speer hot cor 145, and nosler partition 150 (long) are about the only bullets beside what I have to test.

I see the Winchester PowerPoints blow apart in water on YouTube.
Troy says the new core lokts ain't great either.
 
I think what I do next is load the #1913 gameking with (3) powders in (3) charge weights each. See what kind of results I get.

That #1913 is the perfect shape for the 284 short action. The boat tail lets the powder come up around it easier than flat if you had a "full" case

I'd ask what powders you're using....

The Speer 145gr BTSP, the BT will be below shoulder on 284 cases I have. What I do is load max load on powder I may use then measure from case mouth to powder see how long that is. I use long drop tube. Some of the newer powder may give you little better load density.
