Home Forums Reloading Big Game Rifles Nosler partitions in 300 sav - mod 99

I purchased a box of 180gr Nosler partitions for my 300 sav 99. First attempt with 4064 left me with a 2.650 overall length with the powder compressed. The COL for the 300 sav in model 99 is 2.600.

Is anyone using this bullet in their 300 sav mod 99 with other powders? Was thinking maybe TAC, etc might give me enough room in the case to seat this bullet to 2.600.

I'm not saying it won't work, but TAC may not be at its best at '99 pressure. If you try it, go with a WLR or a magnum primer.

Did you try a drop tube when you charged the cases with 4064?

Have you considered one of the 4895's? They'll settle in the case better than 4064, and ignition will be good at standard pressure.

Why do you need a partition at .300 Savage velocities?

did not try a drop tube. I have some 4895 I can try.

Looking for a black bear/deer load, hence 180gr. I have Hornady's 180gr RN. Thought the partition would be a better bullet for bear.

Any other suggestions welcomed.

There is nothing wrong with the Partition, it's just that at 300 Savage speeds most any 180 grain bullet will hang together nicely.

The front end of the Partition is soft, so you should get a nice mushroom even at moderate impact speed.

Nosler has a protected point 180 Partition you can seat a little farther out of the powder space.

Trialed some of 180gr Protected Point Partitions over Varget earlier this year. Result were satisfactory out of my 1899G.
I don't believe Partitions are ever a bad idea.
However, I am hunting with basic 150gr Hornady's over TAC this season.

I use 165-grain Partitions in my Model 70 .300 Savage.

It was originally a .22-250 short action classic stainless. I had Hart Barrel Works screw on a 24-inch number 4 contour with a 1-10" twist.

Both Varget and RL-15 are your friends with that weight bullet in the old .300 Savage.

You can always make your own protected point bullets w/a pocket knife, I do it all the time as I prefer them over the pointed ones. Muddy

I haven't shot the 180 PT in my 99 300 sav, but did settle on the 165 PT with RL 15 as an all-around load. No issues with case capacity, seating depth or magazine constraints, and I wouldn't hesitate to use it on deer/bear/elk...

I would have taken the 165gr Partitions if they had been on the table, but the 180's were the only thing there.

Thanks

I think the 180 Part. is a great choice for BB. I would look into loads with RX15 or IMR 4320.

Just don't see that 15 gr of bullet weight will ever make The critical difference. Whatever makes you, and your rifle happy...
I have come to believe that old standbyes like Partitions and IMR powders perform reliably, without surprises, year after year.
Having said that, I do wonder about 130 and 150 gr copper bullets.

I'd sling 130gr Barnes TTSX's. If you feel you want to sling a Partition, load a 150.

Can't imagine ever needing a 180gr Partition in a 300 Savage.

I just did a little fiddling with some dummy rounds. I have a 33"-34" drop tube I use for blackpowder and just trickled in 38 gr IMR 4064 (Nosler #6 max for 180's). Seating a 180 PT to 2.6", I could just feel the bullet contact the powder with no crunching. Other manuals show up to 40 gr of 4064 which will give you some powder compression even with a drop tube.

John Barsness has recommended 4895 with 150's, but goes to RL 15 (42 gr) with 165's which is what I use. Hornady 7th Edition lists 40.5 as max with RL 15 and 180's. I just drop tubed that charge and seated a 180 PT to 2.6" with no powder compression. That's probably how I'd go with 180's, though Varget may also be worth trying...

Ball powders will obviously give less load density - you mentioned TAC. Big Game and W748 also come to mind...

I agree on the 130 TTSX - that'd be my 1st choice, but I have a big pile of 165 PT blems that shoot great also...

Yeah, those 180gr Partitions in a 300 Savage never work.. Well, maybe it would.




My gun loves 180gr Partitions, far more accurate with them than with 150's and far easier to work up a load than with 165's. And my hunting area keeps shots short enough that I don't need a screaming 130gr to shoot flatter and farther... because I'm not going to ever shoot farther.

The 180's work, and work well. Not for all situations, but no one solution does. I've used H4895 and IMR4895.
