Swiss Arms Question

1:7 all the damn way. It will fire the 55 just fine and you can shoot the heavier/longer stuff, as well.
 
You probably can't go too far wrong with either, but I would pick 1:7 over 1:10 given equal price and availability. A 1:7 barrel can shoot the longest bullets on the market, while still having the ability to handle the shorter, lighter bullets.

Contrary to popular belief, many 1:7 barrels can shoot very well with light bullets:

All of those bullets seem to be "high quality" whereas most of us including me shoot a ton of 55gr Federal AE.

I just don't want to have a 1:7 and have to put only high end ammo thru it.

I had read the danger with "low quality" lightweight bullets in a fast-twist barrels was that they can be spun apart. (Disintegrate in flight before impact.) I've never heard of this happening first hand. Also, 55gr is not *that* light. Federal AE is not especially low quality.

If you mainly want to shoot the finest-cheapest 55gr/62gr fmj you can find, you're probably fine with either twist rate.

My questions are (since you're obviously shopping) : Who's got the best prices on these rifles at the moment? I seen prices ranging from $3300 to $3700. Who's stocking which barrels? Do they still make the Back Special target with the fold-down sights?

Lots of 55 grain FMJ has been shot through lots of 1:7 barrels without any problems. All things being equal, why not choose the more capable barrel?

The only real issue is that some very light (40-45 grain) bullets with thin jackets can disintegrate in mid-flight when shot out of some 1:7 barrels. If you encounter this, try a different bullet of the same weight. The blanket statement that "1:7 barrels can't shoot light bullets" is not valid.

I think the mythology around 1:7 barrels started as a result of marketing on the part of one of the lower-end AR manufacturers.

Personally, I eagerly await the opportunity to test some of my 40 grain loads for my CZ bolt gun in my Daniel Defense M4 once it arrives.
 
So........ it's the 1:7 I should get? I'll be shooting AE 55 gr most of the time...

Definetly! I got a 1-10 and have multiple thousands of rounds through it. It's been great but I got mine for 2900 new 3 years or so ago so I got a good deal and beggars can't be choosers, if I was buying again I would get the 1-7 without a doubt. Don't limit yourself and learn from my mistake u will eventually regret the 1-10. That said if a great deal comes up on a 1-10 don't hesitate to "pull the trigger".

My 1:7 eats all the 55gr I feed it. You don't need to put only high quality ammo in it, mine shoots American Eagle bulk 55gr, and nothing more.

The 1:10 will do fine for you as you thought, but the 1:7 will too.

Like I said before, simply buy whichever rifle becomes available for the right price, if it be a 1:7 twist, then so be it, if it be a 1:10 twist, the so be it, as you said, your shooting cheapo ammo, and really, I would bet money that shooting 55gr ammo you wouldn't notice the difference between the two twists. I have both a 1:10 and a 1:7 and shooting them side by side with 55grAE they both shot the same, so really you'll be happy either way, just find one for a good deal and take the plunge, regardless of what twist the barrel has!
