165gr Ballistic tip, 300 win mag

[baltz526]

Having been able to find IMR7828. I started a new load project for open country deer. Nosler had some 165gr Ballistic tips in stock a few weeks ago, So I picked up a few bags. Remington 9 1/2M primers are in the cases. The goal will be 3100fps in the 24" Ruger. Search turned up very little on the 165g BT in the 300 win mag. IMR7828 is one of the very few powders I have been seeing And It is one I use in a couple different loads. Picked up an 8lb jug to go with the little I had in 1lb cans. 300 win mag burns up a lot of powder, So until the supply chain fills back in with H1000. I'll at least have a few years of Target/Practice/hunting powder.

IMR7828 works real well in the 300. I don't think you'll have any trouble attaining your goals. Can't wait to hear how it works in your rifle.

With the Reworked Trigger and Softer Recoil Pad It Is working great with my Standard 200gr Partition Elk load. Link To Trigger fix for Ruger 77 MKII is http://www.centerfirecentral.com/77trigger.html

Print it out and remember the drawings. Just polishing the contact points helps a lot If you do not want to go the full rework.

 

[JD338]

That should be very obtainable and will make for a great long range deer load.

It should still be running about 1650FPE out at 500yrds and close to 2000fps. I never shoot that far but I could.

I first ran the 165 Ballistic Tip and a .300 Win mag (a tang-safety Ruger 77) back in the 1980's when the Ballistic Tips were first introduced. Also loaded them for a buddy who had a beautiful Win Model 70, in the mid 1990's.

Whiz-bang combo for deer!

Those original Ballistic Tips were a little fragile for the 3100 - 3200 fps mv, but very accurate. GREAT at longer ranges, devastating at closer ranges. We saw some pretty ugly results, albeit fatal, because the bullets expanded too rapidly on contact. Today's Ballistic Tip bullets have a heavier base & jacket and should perform better. In recent years I've been very impressed with them from the .30-06 and .308 Win. Haven't pushed them nearly as hard as I did back 20 years ago with the .300 Win mag.

And yes, 7828 works wonderfully with the .300 Win mag. I saw very impressive results with the big 200 grain bullets and 7828.

Thanks for the trip down memory lane, I haven't owned a .300 Win mag in quite a few years now. Good cartridge!

There is a difference between Nosler published Data and the Quick Load. I expect to hit 3100 at 78gr in this rifle. + - 1/2gr. It will be interesting to see how close the Data is to reality. Lyman data and 7828 has been within a few FPS on a couple loads. Lyman shows 3149fps at the MAX 79.5gr using the 165gr Partition in WW brass. Nosler shows 3192fps at 80gr 7828 using 165gr to 168gr in Nosler brass. Quick Load looks a tiny bit conservative.

 

[SJB358]

It is hard to be real accurate till I have your H20 capacity. If I had that to factor into the program and your OAL I can get some more accuracy from the data.

I've played with IMR7828 a little in the fall and this is the load i worked up to:

Winchester Nickel Cases
79 grains IMR7828
Winchester Magnum Primers
Nosler 165 gr. AccuBond
Chrony 10 shot average was 3292
with no signs of pressure, I decided to stop at this point.

Rifle was a Winchester model 70 with 26 inch barrel. I don't have that group, but i
do have a 7 shot 100 yard group (a couple of fliers) on my phone that i can post later.

 

[SJB358]

That sounds like a screaming load. That would be a dynamite load for alot of game.

 

[baltz526]

It is hard to be real accurate till I have your H20 capacity. If I had that to factor into the program and your OAL I can get some more accuracy from the data.

The sized WW brass has a 90gr water capacity to top of case. 84gr to base of neck.

 

[SJB358]

I'll check it out once I get home, or maybe Mike can run the data if he sees this.

 

[baltz526]

To get the water weight I set a primer backwards in case, I also rounded down from the peak average. 84gr should be on the conservative side. All my brass shot in this gun was resized, so I could not measure a fired case. I will test it after the next range trip.

 

[SJB358]

Rgr that, sounds like a plan.

 

[baltz526]

PS: OAL is 3.400"

 

[SJB358]

That was ran with 90 grains H20 cap.

I planned to work up to 78gr. Looks like it is still in the ball park.
