Deciding long range caliber for blaser

As some of you know, I’ve been wanting a 300 win mag barrel for a little while now. However, after talking to an ex-sniper and current long range shooter about it, he showed me something that talked about the big magnums not being good for long range target shooting. Something about them being designed for power out ot medium range, but accuracy starts to suffer after medium range. Don’t know how 100% accurate it was, but it seemed believable.

But that got me thinking. I saw blaser offers several other calibers for the lrs2, and some looked like they would be an even better choice for long range targets. There’s a 6mm and a 6.5×55. I know the 6mm is supposed to be a great shooter, but I know nothing about the 6.5×55. What would you guys reccomend for long range targets?

Anybody have any experience with either of the two? I’m thinking about using it for 1000 yard competition. These both have 5 round mag capacities, so I could use them in high power competition as well, which would be awesome.

I was having a hard time saving up for a new barrel. If I can find one of these that will work well for me, I may look for a trade or to sell my .223 barrel to get one. I like the .223, and it fits what I do well, but if one of these others can do it better, I’d like that even more.

The only real hunting I do is white tail deer out to 100 yards, and occasionally squirrels out farther. But the point is, this will be mainly for target use, so it doesn’t have to be a cannon like my 300 RUM, just a great one to punch holes in paper, close together, a long way away. 😀

Thanks guys!

Good thing about this rifle is that parts are so expensive it gives me lots of time to think about what I’m getting before I actually get it. 😀
