30BR and N133

Was just wondering if anyone has tried 133 in the 30BR? Burn charts show them very close, yeh, I know. But maybe with a 125 grain bullet? I have shot the 135 SMK in a 1/17 barrel and they stabilize just fine. Takes about, if I remember 32.4 of 4198 to get 2850 fps. Surprisingly accurate. The higher BC bullet calculates to have a slight advantage over the usual 112-116's in the wind. Anyone? Just curious.

Just bought a 30BR and I have been playing with N133 in it.. Shoots real good. I filled it up to the neck, no pressure problems, but I have backed off 1.5 grains and its more stable. Was shooting with a lot of wind challenges. More stable than the 6ppc in the wind.

Also playing with 8208xbr, getting the same results

I would have to disagree with that. I really dont think there is anything worse in the wind than a short fat 30BR 30cal bullet. I am actually thinking about doing something different for the famous fall winds at st louis. Man is it ever grouchy!! I think a 68gr 6ppc bullet is a better choice in the wind than a 30cal 118 or even a 135gr bullet anyday. I tried to shoot some score targets the other day here at home in a 20mph wind and it was awful. I pulled out the 6ppc and started to at least hit the 10ring. Just my experience. Lee
 
Well Skeet...I guess we'll have to agree to disagree on bullet weight results. With no names mentioned; the 2009 Hunter Nationals Equip list listed, Competitor A; BIB/112/ Comp B; 10-X/115, Comp C; BIB 112; etc., etc. All with V133 and one with H322.

But...no matter how you play it, the talent of the shooter and the ability to read the conditions as applied to your rig, wins the day.

Skeetlee, for a ten MPH perpendicular cross-wind, at 200 Yd., here's the "rocket science": if you're sitting next to me shooting a 6PPC and getting an 'honest-to-God' 3400 FPS, and I "give" you a very FAVORABLE .28 BC (it's more likely a lowly .26-.27), your 68 Gr. bullets will be dragged almost exactly the same distance as will my puny (short/fat) , but much better BC 112, thirty caliber slug, exiting the muzzle at a measly (easily obtainable) 3000 FPS - in this comparison, 2.0".

If you're 'missing' with your thirty, compared to your 6, you're letting your mind mess with your confidence/decision making. :eek: What's more likely, especially if you cannot meet or, exceed these figures (68 Gr. 6mm, .28 BC, at 3400 FPS), is that your 6mm bullets are falling slightly behind.;) Oh, and If I'm coasting along with a 118 at a cool 3050 FPS, well, you ARE fallin' behind. :rolleyes: Keep 'em ON the X!

A better explanation is there is something slightly off with your .30BR. When it comes to .30BRs, Randy KNOWS, both the theory, and through years of work & experimenting.
