thoughts on new project.

couple of questions to throw at ya.

1st of all have settled on the 6.5 cal, mostly because i want something different.
1st question , does a 6.55X55 AI give enough of an increase in velocity over the standard 6.5x55 swede?
what kind of velocity in a 24" to 26"barrel?

2nd I have heard it said that the 6.5-284 does not feed real well. ?

this will be a deer hunting rifle with a sporter weight barrel. The 6.5-06 is another option, but i'd rather not go that route, I would prefer to use properly headstamped brass, although i realize the 6.5x55 AI would not be stamped AI, at least it wouldn't be stamped 25-06 as the case with the 06.

    Your looking at about a 200fps increase going with the AI. As far as feeding is concerned with the 6.5x284, Savage is making a production model for 2010 in a repeating action. This tells me that feeding should not be a problem.

    Re: thoughts on new project.

    I went with 260AI based on this article, and the fact that my guy had the reamer.
    Terry's Tactical Two-Sixty AI

    So far getting 2860fps on a stiff fireforming load of H4831SC. I fully expect to be 2900-2950 fps from a 28" bbl with the finished loads. which seems to be the sweet spot people are looking for in the 6.5-284. Brass is a little more available than -284 brass, slightly less costly. Just like the article mentions, I'm getting low neck thickness variation and low runout with a very little sorting of new brass which equals less prep time and more shooting= yay in my book

    Any strait wall or AI is going to be a little trickier to feed.

    edited to add: not much problem finding detachable magazine sizes that fit the *08 cases either if thats your game

    Re: thoughts on new project.

    actually am seriously considering just the plain old 6.5x55 swede, which i understand is WAY UNDERRATED. seems in a modern bolt and higher pressures, a 125 grain nosler partition can easily be pushed to 3000 fps, and that even most reloading manuals for the old swede lean toward the conservative side when it comes to pressure. Over the years iv'e shot a pile of deer with the wiz bang boomers, mostly 300 winny and almost as many with a 7 rem mag both do the job well. But these last few years been shooting the 25-06 and seems they go down just as fast with a whole lot less powder and fuss, the last deer being just last week. The shot was from one side of the hollow to the other, 175 yards tops, but had to sneak that little bullet between alot of trees, squeeze the trigger nice gentle buck to the shoulder and wal-la.... he went 5 steps if that. so anymore i like the sound of 50 grains of powder vs 75....sweeeet...... and a 6.5x55 swede seems just alright.

    The 6.5x55 Swede is a long action caliber. Its casing is longer than the 260 and will out perform the 260. I remember reading an article that explained this, but can't remember everything. I am seriously considering this caliber for my 6.5mm cal. if I don't just jump to the 6.5x284.

    Another bonus for the 6.5 swede is the Lapua brass

    Re: thoughts on new project.

    I have never used Lapua brass... what makes it better than say win brass cases? Also any factual info on top velocity on the 6.5x55 swede and the AI version would be appreciated, note: i,m not intrested in velocity figures in a 28" barrel i will be building on a 24" or 26". some will say the swede is at it's best at moderate vel..... but i have alway's been one to tweek as much as i can from every cartridge i own..
    thanks
