With H 4198 and VV N130 getting so hard to get. Just want to ask of anyone has tryed the Accurate LT-32 in a 30BR i know it work ok in the 6ppc and even in a 223
 
For anyone shooting 30 Major, it's going to take 34.5 grains of LT-32 to get a competitive velocity. You need a long-drop funnel and a slow trickle. Once there, it shoots well.
 
The lot of Lt 32 I have is quite a bit hotter than any 133 I have ever had. I was doing some testing one day with it and was looking for the top end, I found it at around 55 cks, along with some ejector marks. WOW! I my have to check it out in the 30BR to see what it does.

I have played with a .150 short 30-30 that has identical capacity to a 30BR. Here are powders that worked, and approximate velocities in my 22" barrel. Bullet is 115gr Berger. As you can see, some of the slower powders actually did produce fair velocity because they are dense enough to get a lot in the case. The main thing is to notice just how much it took of powders like H322, Benchmark, and older 2015. It takes a long drop tube, and a compressed load. I actually used 36.3gr of RE10 in Colorado to take the 2 gun win. Chronographed velocity was around 2980.

34.5 RE7 - 2958
36.0 RE10 - 2934
33.5 H4198 - 2935
34.5 H4198 - 2997
34.5 N200 - 2963
37.0 Israeli 2015 - 2927
38.0 H322EX - 2987
38.5 Benchmark - 2932

Yes, I did mean Reloader 10X. I should have been more plain. Of all of the slower powders like 2015, Benchmark, 322, and 10X, the 10X was the easiest to get enough in the case. Obviously H4198, N130, N200, and RE7 are the dump easy and shoot powders. Just picturing 38.5 gr of Benchmark in a 30BR is hard to wrap your mind around, and almost equally hard to actually do. Now as you can see, my chronograph doesn't read high at all, some would argue that the velocities are on the low side. I make this point because the same chronograph clocked 3520 fps average of three shots with 40gr of H4198 behind a 102gr bullet in the full length 30-30. Those same three shots went into a .060" group.

My opinion is that it is too slow to be very practical. Here is the velocity it made in a full length 30-30. Notice how many grains it took to make decent velocity. I think I could run it around 3000 fps at around 41gr. and it wouldn't be too hard to load. I think it would be hard to get over 2850 fps in the 30BR. I can not comment on the older IMR8208. It may be a hotter powder.

42.5gr - New 8208XBR - 3105 fps with 118gr bullet

Vv powder

Why not VV N120 ?? Is the N130 better og are N120 to fast ?

I'd tend to agree. I have both, thought the .30 PPC is new to me. However, Roger Haney, who use to post here, was once sent 4 pounds of N-120 by mistake. The vendor replaced it with N-130, but that gave him some N-120 to play with, even after he gave me almost 2 pounds :)

Roger remarked he got excellent accuracy with the N-120 in his .30BR, just not quite the velocity. Don't remember the details, but I imagine N-120 could probably be fussy in a BR, going from what would be considered a low velocity to too much pressure at the drop of a hat.

Having said that, I shot a .30 BR for a number of years with a MV of around 2,750 fps, using a 118-10 BIB in Heavy Varmint. A bullet that compensates some for lower velocities. Shot mostly in group matches. Didn't think I gave up anything, including 300 yards. A number of top 10s, including a 300 yard SE regional shot in an (almost) hurricane. Shot against the usual SE region suspects, many of whom can shoot far better than me. Bart & Billy, Ed Watson, Jeff Summers -- Jef Fowler, & on & on.

The point here is if they are accurate and repeatable, loads with lower velocities aren't the insurmountable handicap they might first seem.
You still have to be able to read & shoot the wind, 2,750 or 2,950 -- or 3,550, for that matter. I'll take a slower load that is more accurate every damn day.

Esp. if no other powder is available.
 
N-120 is excellent in the 30 Major which is between the 30 PPC and 30 BR in volume. It meters like water and you do not have to slow-trickle.

It's not like 4198 in the 30 BR, though. You can get over pressure.

I'm currently trying LT-32. It's tedious, though, to slow-trickle it. If a full case is a happy case, those cases are really happy.

But when they get tough something going a few hundred feet faster always performs better.

So shoot a .308. Or even faster.

Blah Blah Blah. Just another case of wives tales perpetuation.

The Europeans stuck with the 6BR & long-range bullets for quite a while in 300 meter ISU matches -- that "better in the wind" theory. Then someone discoverd a PPC with BR-grade 68s performed just as well, and that became the new kid on the block. In the end, it's (1) barrels (hard to find) and (2) bullets (getting easier every day), coupled with good shooting. And since we're all real good, maybe a little luck. Esp. some luck getting that great barrel without buying 30 or so.

Edit

If all you're saying is that there will be one of those 1 in 100 days when better exterior ballstics -- higher velocity, bullets with less drag, etc., will give you a better chance to win a match, I don't disagree. I'd just rather concentrate on the other 99 matches.
