165 Partition/ .300 WM powder suggestions ?

[lhsako]

Will try IMR 7828 after blatz results...however all rifles are not alike. any thoughts? H4350 or IMR 4350 would be a good start. RL22 is an accurate powder. I would like to hit 3,100+ FPS. what has worked for you ? ty

 

[SJB358]

I used IMR4831 with mine and 165 IB's. Worked real well.

Take a look at the below and see if any of those looks right.. 3100 in a 300 Win Mag is a pretty easy going load..

Cartridge : .300 Win. Mag.(W)
Bullet : .308, 165, Nosler PART SP 16330
Useable Case Capaci: 85.227 grain H2O = 5.534 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Agree, 3100 fps with a 165 is a piece of cake with the .300 Win mag. A 180 can approach or reach that, with a bit of a barrel...

yea, I normally max them out too. what are you and SJB getting at the muz w/the 165's? and thanx for the data SJ!!

 

[SJB358]

I got around 3200 with 165's with IMR4831. I'd have to look up the numbers but it was a book load. Shot excellent as well.

 

[baltz526]

I have Shot H4831, Re22, H1000 with the 165-168gr bullets in the 300win mag. All can be accurate but of these 3 H1000 Is the best powder.

 

[lhsako]

you guys having me thinking,,,,this is to be a deer/black bear load.penetration on raking woods shots if a nice bear appears. sometimes long shot on the bucks. would one of you plz provide the quick load for the 180 AB ? break 3,000 FPS and w/ good accuracy,,,,BAAAM. 8) I thank you in advance !

 

[SJB358]

Here are some ideas. Let us know if there is another powder you wanna see.. Plenty of powders out there to get the 180 up over 3000 pretty nicely.
