30BR using LT30 powder

[JEFFPPC]

Ed Bernabeo and I both tried LT-30 for the first time last Sunday in our first Match at Tomball.
We both shot 35.3 grns behind my 112.
I shot 23X’s, Ed shot 22 For 1st and 2d.

The temperature was in the high 30’s, low 40’s.

Are you compressing it?

Jeff. When LT30 first became available in the beginning of 2015 I started out using 36.1 in my 30BR and it wasn't compressed. I have a feeling that the newer lots are faster than the original 12-15-14 lot. I'm wondering if the newer lots vary in volume capacity like some lots of 133 in a PPC case.

I use a 19" drop tube Frankie.

What speed are you getting!? How many grains??? Never mind, I read 36.1

 

[gunsandgunsmithing]

A 19 inch drop tube is begging for a slightly faster powder, that works...imho.

Mike I use that 19" drop tube all the time from my 6PPC's to my 30x47 and anything in between.

Frankie. To answer your question I was using a 23" 18TW Krieger with 118 EPS HBN coated bullets. With 35.8 I was averaging 3044. With 36.1 it was 3080. Like I said it was the first run of that powder. I bought 176 pounds of the stuff and I gave up on it because it never shot as well as N130 or H4198. I sold most of it to a bunch of guys from GA and SC. I would like to chrono the current LT30 to see if there is a big difference because I still have about 13 pounds of the 1st run stuff. Frankie. I'm still trying to recover from getting my ass handed to me at an IBS 2 day state shoot in Johnstown, NY. All 13 of us got beat at 200 yards by Scott Miller from NY with his 22 Miller. It's like a 22 Waldog. Man that thing was hooked up. I was 1st loser with a 250-6X but He shot 11X's with a dose of LT32 and some 52 grain bullets with a speed of 3550. He put up 1 more X at 200 yards than he did at 100. Go figure.

@JimPag
Here is some lt30 crono. Clines 108

I saw very similar velocity and have had decent results with Lt30. I just received 8lbs of H4198 so I can now compare the two.

35.7, same place I am at with Barts 112s.

Got my hands on this:

So I can now compare the unobtainable H4198 with Lt30 and N130.

I started at the same seating depths and bushings that worked with Lt.30. I dropped the load down from 35-36 to 33.8 to 35.3.

The top row I shot a couple of days ago. It did not look good so I backed out of the lands .005 and also decided to work up higher since I was still lower on speed than what shot best with Lt. 30 and N130. They both shined at around 3075 fps+-. The second row was closer to what I expected. 34.3, 34.9 and 35.3 were all .0 three shot groups. I like 34.9.

I will increase the powder charge a bit more and hope that I can find a larger tune window.

Sorry if I missed it but which bullet are you shooting ?

You bring up a question I have. I read a piece from Randy Robinette stating the powder, refering to the H4198, needs to be slighty compressed for best accuracy. I wonder if the is true with the Lt30. If just dump it in it is compressed. If I pour slow it is not compressed. Any thought on this from those who have been using it?

Try it and see ? ;}

 

[JEFFPPC]

Try it and see ? ;}

I did and now I know, thanks.

 

[P1ZombieKiller]

I did and now I know, thanks.

what do you know?

 

[the long shot]

I found LT 30 was almost 1 for 1 replacement for H4198 and consistent. Shot great and even bounced between 4198 and Lt30 with no zero change at competition. I shoot 118-7 BIBS and Cheek bullets

 

[Ccrider]

Cline’s

Hi fellow student, at my age so much to learn and so little time.At least you and I know who we are. Best lesson learned is to .....Never think you know it all.

Link, I have not shot enough to form an opinion. At this point I am just dumping the powder and allowing it to lightly compress. It is shooting pretty good.
