Home Forums Hunting & Shooting Hunting Rifles What's the heaviest bullet for a 9 1/8 twist .243?

Just curious. Thinking of putting together a new toy that'll buck the wind a little better than the 22-250. Open to advice.

Should be able to get 105 AMAX's to work

Yep - I've got a factory 700VS that shoots the 105 A-Max's really well. First powder I tried was Retumbo and that's where I stopped.

Wanted to bump this. Considering a factory 243. But the factory twist of 9 1/8" has me concerned. Altitude will only be 1600ft or more. From what I have seen, none of the high BC bullets, 105 range, will work.

Jesse... give the 105 A-Max a look. I'm in the process of putting together my second 243/243 A.I. using a 700 takeoff together. at your elevation, it will stabilize it...

The more speed, the better the odds of a "tweener" bullet stabilizing right? A 26" tube would assist this.

Speed helps but not near the amount that cold hurts, if that matters.

You won't need the increased RPMs, it'll likely spin them fine from the get-go.

115 DTAC's and Bergers absolutely would not stabilize out of my 9.125 tubes but 105's always did.

Hey Jess

At 4000 feet my 24" 700's wouldn't shoot them very well at all. I will try the 26" SPS varmint this week. Any excuse to burn some powder.

Careful, you might get (crazy) people all stirred up if it's discovered there are 6mm's that have numbers advantages over a .243, and 105's.

Or perhaps this'd be the perfect opportunity to point out how vastly inferior the 6mm's are, when compared to other calibers. You know, start chit-slingin' 'bout something that wasn't being discussed.

Nahhhh, I'll leave that for The Clown.

Sounds like he just got a crazy person "stirred up"...

You believe. A 7.5 or 8 twist 243 WILL shoot a 105, no speculation. My 9 twist 243 Ruger did not like 105's. I cannot see ever hamstringing yourself right out of the gate, certainly would never build a 243 with a 9 twist.

He's not building, so my suggestion of the 105 in a factory 700 barrel was based around that. Building from scratch, I'd most surely buy an 8 twist.

That being said... I've had success with the same combo before, and the JBM stability calculator is in favor of it (I don't place a huge amount of faith in this, but it is helpful).

Just my thoughts. It'd be worth it to buy a box or 2 at least.

I put a 6mm Rem Barrel on a Model 700 Long Action...
heavy magnum contour, stainless Pac Nor barrel...
with a one in 7 twist....

It is the most accurate rifle I have ever owned...

it will shoot 115 grain Bergers, all day long at 3250 fps...

yet 75 V Maxes and all the 75 grain HPs on the market, still work with that fast of a twist, and leaving the barrel in excess of 3700 fps... ( yeah a little hot, but doesn't seem to phase the rifle or the brass)

A 7 sounds like a winner, a 9 is a dud.

(Brad's tube is a custom, but a 1-9" still).



these guys have had some luck with the combo, 105s in a 1-9".

1 week ago. Factory 9.125" twist, 105AM, .243AI...

Nope. I am not building. Cruising for a left handed rifle on the cheap. I'd build on a 8 twist or more given the option. Just contemplating on grabbing a 700 SPS Varmint and cashing in on a limited time rebate. Getting the rifle for wholesale plus $10 in addition to the $50 rebate gets me into a LH SA 700 action with bottom metal(plastic) probably cheaper than I could buy one used.

I don't currently have anything in .243 and thought I'd burn powder and better my LR theories in the mean.

Even the 95 Bergers at .480 look good to me for ringing steel 800 and under.

You'll be rocking with that setup. It'll get you to 1k easily.
