243 100 grain Nos partition
 

Anyone here have any experience with a load and ballistics for this bullet?

RE: 243 100 grain Nos partition
 

I had pretty good luck with IMR 4350, although my gun shoots the 95 gr. Partition a little better. Terminal performance was about the same. Lots of penetration at the expense of a little smaller wound channel than conventional soft points, like the Sierra 100 gr. Prohunter.

is a good site for load data, always crosscheck the data with at least one other source to avoid printing errors.
assuming a muzzle velocity of 2800 fps a 100 grian nosler partition in .243 diameter sighted in 3 inches high at 100 yards

the bullet will impact 3.5 inches high at 150 yards, 2.5 at 200 yards, dead on a 250, 4.5 inches low a 300 yards, and 10 inches low at 300 yards.

Great! I actually thought of using the 95 grian instead to help MV. Any experience with those?

RE: 243 100 grain Nos partition
 

The 243 has more than enough velocity with the 100 grain bullet. You are on the right track with the 100 grain Nosler Partition.. IMR 4350 should work well. Sierra and Hornady call for 42.0 grains for 2900 fps.

Sweet! I might roll with that recipie. Do you think the MV would be affected noticeably by using a 95 grain instead? WOuld it stabilize better?

RE: 243 100 grain Nos partition
 

I have generally gotten the 95 grainers to shoot a little better out of true 10" twist barrels. All the new Remingtons have 9.2" twists, so they may shoot the 100 gr. bullet bettter. You'll probably just have to try them and see. The difference in velocity or terminal performance will be minimal.

Another bullet definitely worth trying is the 100 gr. Sierra Pro Hunter (flat base design). One of the all-around-does-just-about-everything-well kind of bullets in this caliber. Has also proven to be accurate in just about every rifle of this caliber I have tried.

I really like the Pro-Hunter bullets as well. I use the 120 grain in the smaller 7MM and have had great performamce from them. I didn't try them in the 243 though.

I presonally Shoot 100gr. Sierra Pro Hunter with 42gr of RL 22 out of remington vls.shoots great 3/4 inches 100yds. I found a website offers bullet test load packs. www.bulletdudes.com

RE: 243 100 grain Nos partition
 

So do these pro-hunter bullets hold together pretty well? Are they a Locked bullet or bonded?

RE: 243 100 grain Nos partition
 

NO - they are just a "regular" bullet. Sierra Gamekings are a little softer than the Pro Hunters. The Pro Hunter is one of those solid dependable bullets that expand reliably and hold together well over a wide range of impact velocities. Sometimes the core comes loose from the jacket at the very end of the bullet's terminal path, but this doesn't really affect the wound channel. They are particularly good in the 100 gr. 6MM. With good shot placement, everything from coyotes to elk can be taken with this bullet.

I definately would choose the Nosler Partition over the Sierra for anything bigger than a small deer. Having used the 243 extensively for hunting everything from woodchucks to mule deer, I am quite familiar with it's terminal ballistics. Using a 95 grain Nosler Partition, and pushing said bullet at a MV of around 2900 fps...you will achieve similar penetration to a 30-06 using a factory 180 grain Remington Corelokt load. Chest shots with Partitions vaporize the heart & lungs. The pay off of using the Partition is when things dont go perfectly. You have the bullet necessary to punch through a bone or handle a less than perfect angle. Without a premium bullet, the 243 is a poor choice for anything but a broadside side. With the Partition, you can accept a less than perfect angle. Also, I find it nice to have the bullet necessary for when things go bad. In my mind, a Partition is a fabulous hunting bullet. They open very rapidly, yet have the ability to penetrate like crazy.

Personally, I prefer the 95 grain Partition. I also prefer using H4831 SC, as I can throw it. Hornady lists 45.5 grains as max for H 4831 pushing a 95-100 grain bullet.

RE: 243 100 grain Nos partition
 

Well, I think I am gonna give this 95 grain bullet (partition) a try. It does seem a good choice and the ballistics do seem appropriate.

RE: 243 100 grain Nos partition
 

Alright this is off topic a little bit but since it is such a good powder for the .243 I thought I would ask. What exaclty is the difference in burn rate for the H4350 and IMr4350? My dad accidentaly bought the Hogdon instead of IMR and Im wondering if I can replace them with each other? I wont be loading maximum loads or anything. Thanks.

RE: 243 100 grain Nos partition
 

The loads with the h4350 and the imr4350 are NOT interchangible. After looking at the chart..they are pretty close but I wouldnt think close enough to use same loads. I may be wrong though, Im still a greenhorn on loading.

RE: 243 100 grain Nos partition
 

Doe Dumper is correct. IMR4350 differs from H4350. They can generally be used in the same caliber, but with differing amounts or powder. Be sure to check you manuals before assuming you can use a given amount of either powder.

RE: 243 100 grain Nos partition
 

Well, I have interchanged these powders directly one for the other and I have noticed changes of under 50 FPS between them. The accureacy hasnt been affected though. POI seems to be the same as well. But, I am only doing two loads with this, 40 grains for 243 and 57 grians for 30-06. Seems to work pretty well, but I do try to stick with the IMR as a constant. EJ

RE: 243 100 grain Nos partition
 

In the 70's i was shooting my 243 Win. almost daily and used it for everything. When i switched to 100 NP's it was the first time i got any where near enough penetration on deer, to satisfy me. I still think it's a bit light on bigger deer, but with well placed shotsuseing NP's it is adequate.

I also use IMR 4350 when loading load100 NP's in my 243....

what powder charge?

RE: 243 100 grain Nos partition
 

Irarely give out exact loads, as what works fine in my rifle may not in yours. There's a zillion loading manuals out there full of excelent load data.

My fitth edition Nosler loading manual gives a starting load37.5 grains ofIMR 4350 for the 95 and 100 NP's inthe 243 Win.

I already use 40 grains of IMR 4350 for the current load. I think I will try 42 grains with that nosler partition to make up for it not being a boat tail.I know it isnt exact, but maybe it will be similar in drop at 200 to 300 yards. EJ
