bullet weight ?

rebs · February 7, 2012, 09:47 PM

What weight bullets would be good to shoot with a 16" barrel with a 5R 1 in 8 twist ?

jimbob86 · February 7, 2012, 10:14 PM

In what caliber, hoping for what velocity, to what purpose?

Assuming you're talking about an AR-15 in .223 (16", 1-8" twist, 5R, probably a Smith and Wesson one at that), you can shoot any bullet that will fit into the magazine.

Actually, a 1-8" will stabilize the 75 and 80gr VLD bullets pretty well too. They have to be single loaded because they won't fit in the magazine and are pretty much a handloading-only proposition, but there it is.

Good to shoot - I've used 55 gr FMJ, V-max and SP and 62 gr FMJ from Lake City. The V-max was most accurate.

I thought that the 75/77 grain bullets could be loaded to mag length?

That depends on which 75-77 gr bullets you're talking about.

Not all bullets are created equal.

Are you going to tell us which brand can be loaded to Mag length, or just tease us?

140 to 160 grain should shoot just fine.

You are talking about 6.5mm right?

If your talking about .223/5.56 from what I'm reading 62 grain and up will group the best.

It depends:

Nosler 77gr Custom Competitions = Magazine length
Sierra 77gr Match Kings = Magazine length
Hornady 75gr HPBT = Magazine length
Hornady 75gr A-Max = too long for magazine
Berger 75gr VLD = too long for magazine

It's not necessarily specific to a given bullet weight so much as bullet shape. The 80gr bullets, the 75gr A-Max and the Berger VLDs are longer, spikier bullets for shooting long-range.

Wow, thats a selection. I need to dust off the Mini-14 and see if its 1-7" can shoot some heavyweights.

Sure it can, depending on your chamber and throat.

Depends on the magazine

For some, 80gr SMKs fit just fine.
