175gr Nosler Partition in 7x64

[Scrumbag]

Hi folks,

Managed to get some reloading supplies today (shock horror) in particularly 7mm 175gr Nosler Partitions.

So, I was thinking about loading these for deer and boar. We have quite a range of body size here (10kg to 150kg+ between muntjac and red deer)

I was thinking N165 in my 26" barrelled 7x64. Any other suggestions? Reckon the bullet will cover the body difference?

That should hit like the Hammer of Thor. Good bullet in this caliber. I havent used any N powders but in a 26 inch bbl., you should have no problem getting 2800fps with that bullet using slow burners.

Thanks @sestoppelman
Had a play with Gordon's Reloading Tool (like quickload) and with less than the max book load of N165 I'm into the 2700s which is probably going to do most of what I want it to do. Not a seriously long range load so the extra 100 fps probably not an issue as I already have N165 on hand.

Do you reckon it would be worth a crimp? Also maybe a magnum primer?

You are all set for what you described in my opinion. The 7x64 is a wonderful cartridge and the 175 grain bullet is even better in it than in the 7x57. Yes, I think you are all set for much venison and pork!

 

[7x57Joe]

I don't ever crimp lighter rounds for bolt action rifles but, you may find it useful. The mag primers may or may not produce better results you will have to try them.

I think N160 is the way to go...

I dont know anything about the N powders so cant say about primers, I never use mags unless with hard to light ball powders like 748. I always use std primers in the .280 and 7x64. I dont crimp either.

Enjoy both! My wife (of near term Croatian extraction) is firmly of the opinion I should shoot more wild boar...

I have N160 too and it is a good powder for the 7x64 certainly.

Any particular reason for N160 over N165? The Viht website suggests N165 gives slightly better velocity than N160.

No I don't usually crimp unless a load seems to be not doing what I want it to (Certainly tightens up my .223 FMJ loads).

I do wonder about the mag primer for the slower burners and that long case. Might be worth 10rds as an experiement.

I know what you mean about ball powders.

I like Ramshot TAC for my .223 Rem loads and it certainly seems to respond to a crimp.

Can’t say I’ve tried the 175gr partition in a 7x64, but I have many, many times in a 7x57. Sometimes they work, sometimes they have horrible expansion and jacket separation.

My son used a 7x64 for his rifle under all circumstances. The 140gr Barnes TTSX at about 2950fps is the hammer of Thor coming down on animals. If anything, too much energy on deer if you don’t hit any bone is a bit of a problem as they zip right through and then the deer can run 100 yards in that circumstance. He’s bringing it with for all reasonable purposes he’ll encounter on safari next month.

Keep in mind, the Barnes 140gr TTSX is roughly the same volume as the 175gr lead core Partition, so you’re getting similar expansion size but you’re getting a flatter shot with the 140gr Barnes and additional shock from the more intense shockwave coming from the greater speed.

Hi Rookhawk, thanks for the heads up. I will watch for it and see what happens.

The Partition mainly came about as there was a retailer selling them off at half price and free delivery so I picked up 200 of them

I am starting to look into non-lead as it seems to be coming here. Loaded some GMX up and they shot fairly accurately. No chance for on-game experiementation yet though

 

[Scrumbag]

@7x57Joe 160s are a great thing! If I had a chance at those I’d of had them.

Happy hunting and happy deals!

I fell into a somewhat similar deal. I was at the range shooting my 7x64 when an acquaintance asked me if I wanted 6 boxes of 160 grain Partitions cheap so I bought 6 boxes.

I have not seen a Partition fail as some have. Its a pretty reliable bullet considering its sort of the original "premium" bullet and been around longer than many here have been alive.
Its designed to shed the front half and allow the rear portion to dig deep which it does, and in the process retained weight generally runs around 50-70 percent and not the plus 90 percent some have become accustomed to as the norm.
I wont say its the best bullet out there, it isnt but I have just never seen one fail.

I think that is a good way of looking at it.

I think they are effective and perhaps we get hung up on weight retention as it is not the only method of determining effectiveness.

For your proposed use I would consider the 160 grain Accubond, especially on deer. The Nosler Partition 175 grain bullets certainly works on large bodied animals like elk, but I have trouble getting good accuracy with them from my 7mm RM. It shoots sub-MOA with 160 grain Noslers. If your rifling is 1-9.5" twist it might handle them well.

Even in my 7mm RM I use Winchester LR primers. Since H870 is now unobtainable, I am loading RL-22 to 3100 with 160 grain Noslers. I use N150 in the 30-'06 with 165 grain bullets, and in the 7X57 with 140 grain bonded CoreLokt bullets.

Hello Mike.

The Twist rate is a rather quick 1:8.2"

160gr is certainly an option and would work with 160gr Partition and either the softpoint / hp Sierra Gameking of the same weight.

I have some N150 and use it in my 9.3x62 and my 257 Roberts

I haven't tried it yet in my .257 Roberts. I will look up some loads. With powder availability so difficult here, I want to use the 4 lbs. of N150 I was able to buy recently.
