Home Forums Reloading Varmint Rifles Who makes 223 Rem Bolt With Fast Twist Barrel?

Regular loads in one of my Savage FP's are easy to spin apart the Dogtown's.

Remington factory 50gr hollow points will go five into five-eights/in/100yd out of my Wylde 1in8 Montana Rifle AR barrel, about the same as it shoots 77gr SMK's

Savages are famous for really rough bores, which could be the cause of your problems.

Also, what grain Dogtowns are you using? Midway claims a 4000 fps limit, and a 223 could get there with the 34 grainers.

I've never had any problems with light plastic tipped bullets in fast twist 22s, and that includes a decent pile of 223s and 223 AIs, a 220 Swift, and a 22-6.

And sometimes it happens in a cool barrel with standard weight bullets. Several (too many) years ago, I was working on new loads for a 22-250 in Rem 700 varminter with a standard twist heavy barrel. The bullets were some double hollow point 50 grainers from Jim Calhoun. The groups were clustering OK when all of a sudden there were no more holes in the target for the next powder increase. It turns out the bullets were coming apart in mid-air, and those small dust clouds downrange weren't dust at all. Of course, on the outside of the box, Jim had printed on the box "Not for velocities over 3600 fps", or words to that effect. But hell, what guy ever reads the instructions...LOL

That's very interesting. I've shot quite a few Calhoon double hollow points, but not over 3500 fps! Can't remember if that was pure chance, or I actually read the directions....

I have had the odd bullet come apart in mid-air from a .223 with a 10 twist. Speer TNTs and NBTs�.always on a hot barrel day on a PD town somewhere and Ive done enough of that kind of shooting to wonder if maybe the bullet didn't hit a bee or other bug?

Instructions are for sux.

Until a few days ago would a hard time believing that about Ballistic Tips, since have shot a bunch of .224's from various rounds at up to 4400 fps from different twists, often with the barrels really hot, and never seen it happen.

But put some 120-grain Ballistic Tips through a 26 Nosler the other day at over 3500 fps and only two of five hit an 18x18" target at 100 yards. All the other bullets tried went into 1.5" or less, usually MUCH less.

I've had a few Barnes TTSX's shed their jackets...

I thought the 120 NBT had a beefed up jacket?

Marlin XS7 1-9

It does. I've used them and seen them used on deer-sized game at muzzle velocities around 3100-3200, from 1-8 twists, and they worked fine, both in accuracy and penetration. But 3500+ is another deal, apparently.

Nosler just introduced a 120-grain E-Tip 6.5mm, but didn't have any to try.

Cores out of whack/slipping perhaps?

That's odd.
Nosler solid base stuff is legendary for keeping obturation down and imparting rotational torque, by design. The impact extrusion method also is well known for "coddling cores" and keeping/having cores balanced.

I recall us having this conversation and mentioning how speed and twist proof BTs were!

I've never sectioned the 6.5 120 NBT, but have many of the other Noslers. I'd just read that it had a little more jacket. I've found accuracy in the 2850-2900 range and never worried about the bullet coming apart at that velocity.

I've yet to have a Nosler come apart that I'm aware of and I've shot a bunch of 40's in an 8" twist 223, including the Varmageddon. My 223 RAR Predator loves them at 3800fps...

I believe you're thinking of the 120 in 7mm.

Nope. I've sectioned that one. The jacket is thicker at the tip than the 140. I read it's the same jacket, but shorter, hence less taper at the polymer tip.

I've read on here (and heard it elsewhere) that the 6.5 120 is beefed up a tad too.

The 6.5 120 is pretty stout. The couple I've seen recovered were on angling shots, and were classic mushrooms. One of them went through a pronghorn buck's shoulder during it's journey.

I told my contact at Nosler about my experience and he found it very interesting--and brought up the new 6.5mm E-Tip. The fastest velocity listed for the 120 in their manual is a little over 3300 (.264 Winchester) so I don't think they've ever pushed it to 3500+--and the velocity in my rifle was above 3550.

Remington's PSP Tactical.

Salvage

Howa (be sure it's a new one)

I think that's all...

A lot of good info here. Thanks to all who responded. I'm going to take my time picking out a rifle instead of rushing into it like I have in the past. Decisions, decisions.

I vote Howa, for the record...

Remington's tactical model with the houge over moulded stock has a 9 twist. My e shoots pretty good. Just toss the houge and got a hs stock.
