300 winmag alternative for long range

[big flash]

I've been craving a 300 win mag ever since I read Chris Kyle's book lol. Though I have no practical use for something long range now. I don't have anywhere to shoot longer than 200 yards anyway (yet)

Exactly. Years ago, when there was land to shoot on, you could find 1,000 yds to shoot, but it was usually really hard to get out to the targets because it was usually over a few gullies, fence lines, swamps, etc.

With 178gr bulk long range bullets anything in the 350 yard range you do not need to correct or holdover anything. It is basically point and shoot. LOL With a nice heavy barrel and stock and a muzzle brake is actually very enjoyable to shoot unlike many folks think. For a light hunting rifle it is a hand full, still one can be accurate with it. But for deer and average animals will ruin all the meat.

Just trying to revive some interest in case we get lucky...

anyone has experience with these??... These could be perfect to set a new record.

Have you seen these yet Meke?

I saw them but have not tried them.
The main issue is twist... and a tad more grain would be also great in order to provide momentum (not just energy)

Agreed. I've been following them waiting to see more independent reviews. The numbers they are claiming are huge. It looks like a lot more people are innovating in terms of projectiles it will be interesting to see where we are in a few year.

I thought about the 375 ruger as the donor but why not use the RUM with the dakota dies and
then we can use the standard magnum bolt face. It seems like a no brainer to me, what do you think?

The shape of the round seem to me to be a weak point.Such a sharp point especially in aluminum I would think it would be prone to getting bent or deformed changing the ballistics of it .
Are there any ballistic charts for this round or is it too new I didn't see anything at the site?

I think the tips should be fine. One should be careful but these are geared towards extreme long range bolt action shooting. That is very slow shooting so we should be fine.
The ballistics is a great question. This is a wildcat but because it would be so similar to the dakota we could probably use those numbers as reference.
I think we might need to ream some extra freebore but that is not a huge deal.

Lets see....

5.9 mils at 1000 yards!
Still supersonic well past 2000 yards!
More energy and momentum at 2000 yards than the blackout / ar15 at 100 yards!

So what do you think?

What is the recommended barrel twist 1 in 10?
Are you using the Exbal ballistics for your calculations?

I think it would be best a 1:9 but a 1:8 would not hurt. A small sacrifice in the name of stability. I guess the best would be to follow the bullets
manufacturer recommendation but one extra twist will not hurt if extreme long range is posible. Not around here anyway but I will take the rifle down to TX when
I go this winter. This is specially critical going through transonic spectrum.
I used the hornady calculator above for a quick and dirty estimate although normally I use my own calculator I built in excel over the years.
That is what I will use once I start reloading to keep track of batches, tests and also do the ballistics calculations.

Now I am not a "fan" of recoil and I have no need for any of the rounds mentioned in this thread other than the .308 which I swear by out to and including 1000yds. I am not sure how it stacks up with the others however, when I was a lad my father always spoke well of the .300 Weatherby Mag which I think is a belted magnum. Just a thought.

Good round too. Nobody around here needs anything larger than a 308 or 30/06 and for sure the 300 winmag will do everything we ask for.
The issue is that with the win mag the top of the line bullets cannot be used due to the case length so that is why we looked into a tad shorter, wider case w/o getting into overbored cartriges
like the 300 lapua magnum cat or the Norma that are also twice as much or more expensive.

I think the Dakota baseline will work really well forming RUM brass that is plentiful and way more affordable than lapua or norma ...or weatherby for that matter.

The RUM has lots of capacity, is strong and well priced. That is why you see so many offspring from it.

Another orgasmic one is to put a 7mm SAUM in a long action with extra freebore.

This is why...
