View Full Version : Neck Tension for LT-32

Have any of you experimented with LT-32 enough to ascertain an ideal neck tension? I use a great deal of tension with my .262 neck and N133 powder. I use a .256 bushing with a loaded round that measures about .260. Is this too much for the LT-32? Thanks, James

I've did some testing yesterday with neck tension. It doesn't seem overly critical like with 133. My neck is like your's a .262. I've went as tight as a .255 bushing all the way to a .2595. Didn't really start to see any change until about .258 and things started to open up. A couple of more experienced shooters said that the old T powder liked very little neck tension, we didn't find that with the LT-32.

I went back and found the testing done by Speedy, where he compared T to LT-32. He reported using a .258 bushing on a .263 neck. I think that falls in line with what I found yesterday and what you are finding.

I seem to keep going back to 29.3 gr but it's little hot in a .236 bore, I need to find a lower node. What has been your experience with load work up so far?

Mike, I haven't gone that hot. I found enough velocity with 28.4-28.7 gr. This was with lot no. 1. I am expecting some lot #2 soon and will try a different bushings... .2585, .258, .257, and .256. All of my loads thus far have been with .256. Good shooting...James

Been using a .258 bushing for a .261 loaded neck diameter ..... maybe I should be tighter base on these post.

OK, how do I tell the lot # on this LT-32 powder? The only thing I've found on my jugs is a date of 12-21-12.

Have you, or anyone else for that matter found too much neck tension to be a bad thing? If so, why do you think?

As variuos people post their results with the new LT-32 it would really be helpful to all if a lot number is posted. This could keep things from getting confused as happened in the past when the various lots of XBR were not equal to the first lot.

The 8 pound jugs that I received do not have anything in the normal lot number space, just stickers on the bottom that say "12 21 12".
Does anyone have any idea on the lot?

Lot #1 was 5000 lbs. It's unlikely they have started shipping lot #2 yet. Don

An 8# jug a friend has the lot number is the same format as the Canadian/2015. There will be a single digit above the numbers you show.

As to the 5,000# batch of Lot #1, I know of one person who ordered 248# just for his self. His order was placed way before the Sandy Hook tragedy.

Hmm...My jugs are labeled 01.08.13 with the number 2 above the date. I assume the powder I have is lot 2?

According to Keith Anderson both lot#2 and #3 are being shipped. He said that they were shipping the maximum each day. Good shooting...James

Both of my 8# Jugs have a sticker on the bottom 01.07.13 with a #2 on top. If that is the lot# maybe its a good idea to mark that # in the front of the Jugs with a permanent pen. The stickers dont look like they will stick very Long. if this powder is as good as people ar claiming it is. i will stock up some more. Gabe

Doesn't the pressure ring on the base of FB bullets also affect the amount of neck tension and the bushing used?

My experience, no surprise, jibes with Speedy's. I also have a .262 neck and use a .258 bushing which is moderate tension with LT-32 with good results. I tried a .256 bushing and .257 bushing and thought the .258 worked best. The groups seemed a little rounder with .258. I formerly used a .258 with N133. I've been using 28.5 grs. LT-32 with two different barrels.

The apparent lot number on my 1# bottles of LT-32 is 1218121

BTW I've been using the (relatively) new Berger column bullets with LT-32 and am very pleased with the results.

Kinda off topic, but i did get some LT32 ordered. my supply guy is getting it from Grafs and it will be lot Number 1. Grafs told my supply guy that Lot #1 has had better feed back compared to lot 2. Not real sure why Grafs would have claimed this, but i found it interesting. I dont believe it, but we will have 16 pounds if its true. LOL!!!! Lee

Thanks Lou for the info. Like i say, i didnt really think anything about it. The 2015 i have shot sure shoots well, so i will eager to try the LT32. Thanks again Lou for all your effort. lee

For those who haven't seen it Accurate Powder Co. has a PDF available with loading data with LT-32 for four cartridges, among them the 6PPC and .223. The URL is:

They are talking about 2015 lot 2
Lot 2 of Lt32 is the same as one and is still on the dock being ship .
Other than me I don't know anyone that has lot 2 of Lt32


Lou i got 1# cans, i figgured every one was going for 8lb'ers so i would order 1# cans in hope to get some. i did.
on the lable is a gray strip reads 0104132

i was thinking it ment 01/04/13 fill date lot 2 but i dont know that for sure. havent shot any yet. it's like 10deg F and snow right now.

I have 8 1# bottles of LT-32. Mine have gray labels on each that read 1218121. I was guessing that meant Dec. 18, 2012 Lot 1. Sounds like Lou is saying that we both have Lot 1. I wonder why there is otherwise a different number on those gray labels with the powder being so new? Also too cold to shoot here now but my initial tests with Berger column bullets (touching the lands) were tried with three different neck tensions and all look good. I've settled on a .258 button with .262 neck and 28.5 grs. The PDF I listed in the other message suggests this is a maximum load although Speedy said he'd worked up to 29.3 grs.

I have received 3 8# jugs & 1 1# the stickers on the bottom had a 1 above the date on the 8# and a 2 on the 1#
Also in the lower right corner of the bar code on the front of the 8# is the #1 and in the same location on the 1# is the number 2. The numbers match so from what others have said on here I think the lot # could also be in the bar code area.
I'am going to call western Powders to check on my assumptions.

Have you, or anyone else for that matter found too much neck tension to be a bad thing? If so, why do you think?

I hope some folks will opine on this one. I have my opinion but am interested to hear what others have to say.

I have shot this powder and the older lots of Canadian 2015 which is reportedly very similar (which I can attest to). I have performed ladder tests over a 2 grain window, used more than one kind of bullet, and a pretty wide variety of neck tension. Too much neck tension didn't seem to be a big issue, too little and the groups opened up.

Here's where I am probably going to get in trouble with either my analysis or terminolgy. In all this testing, I have never once had a flyer; I mean the one shot that for some unknown reason is a 1/2" or more outside the rest. I think this powder has a very shallow pressure curve and is very stable. The pressure curve is not spikey like some other powders we use.

Last weekend I took my same load that was producing mid 1's on a warm afternoon to a morning score shoot that was cool and humid that changed by the end of the shoot to warm and extremely dry for our area and never changed the load. I couldn't have gotten by with that using 133. It is going to be very interesting to see what happens when it starts to get hot.

I know this is an old thread but am just wondering what shooters are thinking about the newer lots of LT-32 as compared to lots 1 and 2? I have seen jugs with lot numbers as high as 6 and was just wondering how it was shooting as far as accuracy, velocity and weight/density? Any comments?

James,

Ive Shot a good bit of LT 32 in competition. As a matter of fact I won River Bend with LT 32 last week. If you have the correct neck tension to shoot V133 then it will work perfectly with LT.

Bart

Thanks for the powder LOU! You're the Man!

Could be. They are making it in 5,000# batches supposedly.

The LT-32 I got from Powder Valley a few months ago has the 10 16 13 sticker with a 6 above the 16. I have an older HV Hart 6 ppc with a Hart - 23 1/2" bbl. Using Wolf Sm Rifle Magnum primers, HBN coated Bart's 66 Ultras just into the lands, and 27.8 gr of this powder gave a three-shot average 3340' sec, with an SD of 8. Temperature was in the high 50's and low 60's. A couple of 3 shot groups measured around 0.120" - 0.140." Not super I know - but I'm an IBS Score shooter and only shoot groups to tune the vertical out of the load - then it's off to shooting X's and 10's! :) I've shot several IBS 100 yr score targets with it in switchy conds and averaged 3 X's on each target, with good inside 10's and no "hangers" or anything else "scary." So in my limited testing I've found this lot works well. I plan on using this load at the upcoming 100 yd Score Match in Augusta (Maine), on 5/4. I did notice that it is not as clean burning as the Chinese-made 2015 BR I've been using to date.

I bought three jugs in December and all were 10.14.13, lot #6. If they're producing 5,000 pounds per the stuff must be moving well.
