Been using Hornady 87g SP in my boy's 243 with good success - they're not the 'hottest' loads, but they're accurate.

Decided to try some 85g Nosler Partitions for a bit of extra punch.

I know I'm going to have to work up my loads, but has anyone had any experience of how much extra 'pressure' the partition creates?

Nosler's site doesn't have any load data to work with.

Cheers

Very little if any at all....start the same an any bullet of the same weight and work up.

IN my 243s, I don't use the 85 grain partition, because accuracy has really sucked with that bullet.. I'd stick with the 87 grain Hornady or the other excellent bullet in that weight is the 85 grain Sierra HP... it will drop a very large sized deer with no problem.. it is one of the most deadly Sierra 6mm bullets.. on larger game....

Thanks for the heads up Seafire, I was going to use the partitions for pigs and fallow, sounds like the Sierra's might do the job without too much stuffing around...

thanks vapodog - I've read all sorts of articles giving 'dire warnings' of extra pressures...

Starting to sound like b/s to me...?

Yes....the firearms world has a lot of it.

If one is using pure copper or copper alloy bullets or bullets such as the Northfork or TBBC or other that is substantially copper then it's true that the load should be reduced. But the Nosler partition and swift A-Frame is not that way. The very small web of copper in the middle does not present a significant problem for pressures.

The loading data I received from Northfork is simply to reduce by 8% and work up.

I used the 85 grain Partition for antelope in my 243 year ago, I don't have the exact load handy but it was a near maximum load of IMR4064.

I have a max load for my rifle using the 85 gr nosler partition. I used 37.5 grains of IMR 4064. This was max for my rifle.
The link is for the 243 Win loading data, hope it is usefull.

aktoklat, that's a nifty link - thanks!

I've used those 87 Gr. Hornady Interlocks with great success myself. I see very little reason to change. The real key with the .243 is shot placement. As long as your boy is having what sounds like good success with this bullet my suggestion is don't fix what isn't broken.

RiflemanZ, because I live down under, we have limited brands of powder to choose from, and they aren't always available everywhere...

As a result, I tend to stick with ADI 2209 and 2213SC - roughly equivalent (IIRC) to 4350 and 4831SC respectively. A mate is trying to 'convert' me to Win Ball Powders, but I'm reluctant for the above reasons. Any assistance would be appreciated...

Jay, good point!! I've never had any 'bad' experiences with the Hornady, and my boy sure as heck knows how to shoot (he oughta, his Dad (ME) taught him LOLOLOL)... but I figured that maybe he could get a bit more downrange punch with the Partitions on bigger pigs, whcih out here have pretty thick shoulder pads...

Once again, thank you all for your thoughts...

Rugeruser ,
Like to stick to the Aussie powders myself too but have found WXR (same as RL22) to be handy with projectiles over 80 grains in the .243 .
Seems to give a bit better velocities than 2213 .
Haven't tried them myself but believe that the 95gn Nosler BT might be worth a look for fallow and pigs .

This is the same load I use for the 87 gr hornady and the 85 gr sierra,in my rem 22 in barrel.Brother took 4 deer with this load this past yr.Fps is little under 3200 for both bullets.

rugeruser, i think you should load some 85 partitions, your rifle will tell you what it likes,sierra''s shoot great and very accurate, but in all my testing all the boattails any brand loose there jackets and or cores, theres also a barnes triple shock in the same weight class something to think on, target shooting''s one thing bringing home wild bacon''s even better regards jjmp

I had no idea you were hunting hogs. I really like the .243 but on hogs I think I'd move right up to a .308 and use a much heavier slug.

I get the exact same results with a 75 grain HP and 47.5 grains of H 414.....Most accurate combo I have ever shot!

Gidday Rugeruser,

I would go along with Seafire on the 85 grain Sierra HP being a most deadly projectile on our sized game.

It is accurate and bowls deer and pigs like you wouldn't believe. 200 pond boars are no match for one of these through the boiler room.

Also they open up well on wallabies and are singularly spectacular when a hare or magpie cops one. Instant feather duster.

We are using AR2209 (44 grains) out of a 22" Remmy 700. The AR2213sc was a little slow but made a spectacular flash when spotlighting wallies. Seemed that most of it was burning as it exited the barrel.

Have fun anyway

Happy Hunting

Hamish

Hamish,

thanks mate, I'll give 'em a go...

I'm using 41.0 gr H-380 with the 85 gr HPBT out of a 20" Rem 660 and I get about 3050fps if I recall correctly. It is very effective on crows and small fox up to 200 lb deer thru the ribs. Hogs should fall just as well if you punch em in the ribs.

Can't help with the night flash...maybe some type of closed compensator would help. I shot a fox at dusk a few years ago with a .25-06 loaded with 4831SC and I couldn't see for 5 minutes after the shot...that flash was spectacular as well!!
