Re: 300 Dakota- FiftyDriver and others-

In other words, both Jerry and Kirby, would you feel that given the only 100-150fps difference between the .300 Dakota and the .300 Win Mag that I might be better off with the .300 Win Mag?

Is it still true that the .300 Win Mag has about 100fps vel. advantge over the .300WSM?

THanks guys.

Re: 300 Dakota- FiftyDriver and others-

From what I have seen and heard the WSM only gives up a very little velocity to the 300Win mag untill you get to the heavier bullets say 180 and up then their may be a 150-200fps differance. So your looking at a total velocity differance of say 300fps , and if your shooting at ranges under 700-800yds I don't realy think that you would be able to see a great differance and I seriously doubt that any critters will notice the differance. but if your gonna be shooting at ranges farther than say 700yds consistantly then yea the extra 300fps would probably have an added bonus if not the drop with the wind at least

Re: 300 Dakota- FiftyDriver and others-

Thanks for your answer Kirby. I do about the same but draw up the chamber on autocad and have drill stops on the drillbits I use so that they dont go outside the chamber dimension.
The faster you can push a high bc bullet the more you can be off on range estimation. The trajectory created is a smaller arc. Thats why I like fast flat guns, not that I cant estimate range good its just an edge that I dont need to worry about when shooting long distance. There are so many variables, that the more you can control the less you have to worry about when performing shots.
Thats just what I think and it may not be right or wrong but it is a point worth considering.

Re: 300 Dakota- FiftyDriver and others-

Depending on the barrel, the win mag and the WSM are essentially the same. The win mag and larger cases look really good when barrels go long. Otherwise, you are making a lot of noise.

For hunting 750yds and in on deer, I am using a 270 and 6.5-06. Some have successfully used a 308. An '06 or a gibbs would be more of a good thing.

If you are only going to be in the 180gr range, you might want to consider the 7mm - 280 Rem and AI, 7WSM, and 7 Rem mag. Way more effecient bullets and much better wind buckers. On game performance would even be better then the 180gr WSM/win mag/Dakota because of increased retained velocity.

A person I shoot with has a 280Rem and launches 168gr MK at 2900fps. I was shooting a 30 Gibbs with 165gr SST at 2950fps. Both chronied same day. At 750yds, the impact difference on my swinging gong was significant.

The 7mm bullet left a noticeable dent/crater. The 165gr SST just took off the paint.

This will be an all-rounder for Canadian species- Elk, Moose, Caribou, deer, sheep, and African Plains game- up to Eland size.

Re: 300 Dakota- vs. 300 win mag vs 300 Weatherby con\'t...

Well, I,ve come full circle again. I am now considering the plain jane 300 win. mag. for hunting. the above animals.

Which .300 MAGNUM would you use or is there any slight advantage to any of them. Max ranges out to 600-700 yards for paper, less for game.

You have created some excellent responses that we all learn from. Check into the fact that there are two .300 Win. Mag specs, the factory load and a longer mil-spec load that was developed for the U.S. Navy. The longer over-all length load is the way to go, George Gardner tells me that accuracy is significantly better if the chamber is correct and you headspace off the shoulder instead of the belt. I believe that Black Hills Ammo is loading the mil-spec load but doubt that we can buy it, but it would be easy to duplicate.

To further complicate things, in my rifles the .300 WSM matches or slightly exceeds .300 Win. velocities with bullet weights up to and including 180 grains. Accuracy is probably similar, but I would put my money on the WSM being inherently more accurate. I believe that the factory gets the WSM performance by loading at pressure levels that are right up there, have seen primers blown and markings on case heads on hot days with factory ammo.
Since you are interested in hunting to 6-700 yards either .300 Magnum will do a super job, you are well within their capabilities for accuracy and energy dump.
The .300 Win. mag has lots of data, is easy to load for and get accuracy, and you can buy factory ammo anywhere. The WSM is does not have a belt which is a definite plus as far as accuracy and reloading goes, it is a very capable performer and it will enable the use of short actions (which I do not like, short Rems require a single stack mag box which limits how many rounds and also does not feed as well as Winchesters M-70 WSM action). I would get a custom rifle in .300 built on a Winchester WSM action simple as that.

Just to complicate your life, you have not mentioned the new .325 WSM, for the animals you mentioned this is a candidate - 200 gr. Accubonds at 2925 and superb accuracy. My GA Precision built .325 WSM drives tacks, kills bears out to 300 yards with one shot and does not kick as much as some light .300 magnums that I own.
