240 grain bullets for 300 win mag

[Big Squeeze]

Ok, I would have to agree with you Antelope_Sniper it does have energy. And that is what I am looking for. :grin: Well everyone I guess you have talked me into using the 200 grain accubonds for long range shooting. Does anyone have any good loads that might be able to put me at 3000 fps or faster? Then I will let you know how the results are after hunting season. Thanks

..................Don`t be too concerned or influenced about achieving, what seems to be by some, this magical # of 3000 fps. from the 200 grainer. Doing so would be strictly an ego thing.

Believe me, your game won`t know the difference or its affect at any range between a 3000 fps bullet, vs a 2900 fps bullet, or even vs a 2800 fps bullet. However with most, a 24" barreled 300 Win, will be very hard pressed to reach a velocity of 3000 fps with a 200 gr. bullet while staying at or below max. pressure limits. The max velocity for a 200 grainer according to my Sierra manual using a 26" tubed 300 Win., can fire a 200 gr. Sierra BT @ 3000 fps using 75.0 gr. of IMR 7828. Is that load the most accurate? Only your rifle will know for sure!

For a 200 gr. max load, realistically plan on about 2875 to 2950 fps from your 300 Win. I reloaded a 300 Winny for 35 years and most of my favorite, most accurate 200 gr. loadings chrono`d at between 2800 to 2850 fps.

I`ll gladly take 2800 fps to 2900 fps from a 200 grainer that groups very well at under an inch, as opposed to a load firing at 3000 fps that consistently groups at 2 or 3 inches!! Why? Because that is what my particular individual rifle likes and you simply need to find the loads/components that your rifle likes the best.

Your first concern, is to get the best possible accuracy, ALONG WITH, the best possible velocity at the same time. You must do plenty of load experimentations, playing around with different OAL`s, seating depths, powders, primers, etc. in order to find the best compromises.

If you don`t have one already, get a chronograph to accurately measure your results in both velocity and velocity deviations.

Any load, componentry etc., that is reco`d to you here, may not work as well in your rifle. All that can be done here is to help you narrow things down a little. When I had my 300 Win, one of my favorite 200 gr loadings was 65.5 gr IMR4350 @ 2835 fps. A reduced load yes, but a very accurate one as well.

Your rifle is its own individual, with its own fingerprint.

Here is a simulation: Start 10% lower
these are all no more than 62K pressure.


Cartridge : .300 Win. Mag.(W)
Bullet : .308, 200, Nosler AccuBond 54618
Cartridge O.A.L. L6: 3.340 inch or 84.84 mm
Barrel Length : 24.0 inch or 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 62000 psi, or 427 MPa

or a maximum loading ratio or filling of 105 %

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.
USE ONLY FOR COMPARISON !

144 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
