Re: Really...how good IS the 6.5mm?
[ QUOTE ]
I had decided on a 300 win mag for a long-range gun, but lately I keep hearing that the 6.5mm is the latest-greatest thing. Fads come and go, but what are the pros and cons of the various 6.5mm cases over compared to each other and the 300 win mag?
I know the bullets tend to have higher BC and sectional density than the .30s used in the win mag. What kind of velocities do the various 6.5s get, and how are they on game down-range? What's the largest game they're good for, say at 500 and 800 yards? Are they barrel-burners?
The only one I've heard much about is teh 6.5-284...is this the most popular of the group, and why?
[/ QUOTE ] False, the 6.5 has been a round for a vary long time and is no fad. In the words of P.J. Hart when asked how soon does a barrel start looseing it's accuracy, his reply was "from the vary first shot". I take it you are refering to all the current iterations that are used in 1000 yards comp. they are all about the same. Everbody is trying to stay just under 3000fps. The reason is the base of the bullets seem to implode and become deformed @ 3000fps and they give the shooter vertical. This is proven with highspeed photos, that it happens, is a fact know for the last four or five years. This was about the time folks were on the hunt to loose the vertical and started messing with the 6mm. for the .284 WIN case. Most shooters are looking for the golden spot of 2950fps. Which is about max before old vertical rears it's ugly head. Now the problem with the 6.5x.284 is , you ain't gonna get there with a barrel length you would want to carry in the field. Your not going to reach 2950 with a 26" barrel. Competive shooters do worry about barrel life as they are putting a lot of rounds down range each season. Thats why most of the match equipment list show barrel lengths @ 30 inches and longer. They get a good burn with fairly slow powders in these lenghts, and get to 2950fps. the barrels live alot longer than tring to get there with a shorter tube. I have shoot moose with the 6.5x06 using the old screw machine jackets (pre 1975 Nosler) and they worked just fine. But they are long gone. Now days, thanks to WOODLIEGH good bullets live again for hunting with the 6.5 bore. Unless you want to mess around with annealing cases I would stay away from the 6.5x06 ect. and only go with a case like the 6.5x55,6.5x55AI,6.5x.284 not sexey but they will get you there for any hunting you would want to do on all the members of the deer family. If you wanted to build a light weight sheep rifle this would be the way to go also. Now with that out of the way the 6.5mm has been used in comp for a lot of years in europe where they are highly reguarded. It's really in the U.S. that we feel it nessary to re-invent the wheel ever year., thats why you see so many different changes come along in ctg design. I leave it to you to answer the why!
