This post is not for Hoot. I did not know how to move a post from the "Hello to all our new members" thread to a new topic, only how to copy it, so I created a thread for it.

For Greg_R

Hello, new here from North central North Carolina. I am an admitted Handihaulic, I am very fond of the Handi Rifle. My favorites are the 300 Blackout AAC Handi Rifle, the 223 Remington, the 280 Remington and the 45/70.

But I cheated. Along the way I fell for the Modern Sporting Rifles. I have built a 300 BLK and a 223 Wylde to compliment my Handi's. There are plans for a 25-45 Sharps, the closest i can come to the 280 Remington in the AR 15 platform, and a 458 SOCOM to compliment my 45/70.

But there is another problem. I have a little deal working on the side with the Ruger American Ranch Rifle. 5.56 and 300 BLK, but I just met their other sister, the 450 Bushmaster, which has led me here for some advice.

You see, now I am questioning my fledgling relationship with the 458 SOCOM. I have little knowledge of the 450 Bushmaster. I know I like the RARR and the reciever I have for the 458 would work just as well with the 450B. The 450B doesn't seem to be as high maintenance as the 458, cases are easier to find, .451/.452 bullets are plentiful, I'm guessing that a standard 230 grain hardball would make a wonderful plinking bullet for the 450B. And it seems like Lil Gun will be a good powder to feed it. That's about all I know.

I'm hoping to learn a lot here. Hoping you folks will help me make up my mind. Should I push the 458 SOCOM to the side? Should I embrace the 450 Bushmaster and make that my next build. Is the RARR chambered for 450B a good thing? I hear it eats scopes. If i need to staybaway from the 450B RARR I'm sure my relationship with the Bushmaster will end, i will go with the SOCOM. What length gas system for the Bushmaster, what twist? Do I even have a choice in twist rates and gas lengths?

Give me an education, help me decide.
Thanks!
Greg

I don't own a Ruger, so take it for what it's worth.
I've heard nothing but great reviews about the Ruger rifles. Only thing I personally don't like about them is the 1:16 twist rate. It's completely unneeded. However, it doesn't seem to degrade accuracy. As far as being scope eaters, I don't really see how, it's running the lighter end of big bore bullet weights, and it's case capacity isn't very much compared to other big bores either. Recoil should be about like a 20ga slug gun.

As far as AR's go, the normal twist rate is 1:24, which works with just about all bullets one would run in the 450 bushmaster. Some run 1:20 down to 1:16, again it's unneeded, but still doesn't seem to affect accuracy. Some barrels were offered in a 1:32 twist, which you would want to stay on the low end of bullet weight. As to gas length, carbine works, but can be a bit much, especially if your running a longer barrel (over 16"), mid-length is a better choice, even for 16". Rifle length can be fickle unless running a long barrel (over 20").

That's all I got for now.
