    mr.big -

    Howdy !

    I've heard that one of those two "LT" powders was not going to be manufactured anymore.
    What have you heard about that ?

    I gave a can of LT-32 to a benchrest shooting friend of mine, to try w/ his 65's.
    He recently shot a group submitted for potential new world record ( NBRSA ) and did that shooting VV133.
    I imagine he's in no hurry to try LT-32 in 6PPC.

    Maybe Bart will comment. He has the skinny on these powders. I bought 16 lbs of LT32 on his recommendation.

    I prefer Lt 30 and Lt 32 in a ppc! I take them both to matches. Either should work great with the 65s

    NOT true. Another rumor or misunderstanding.
    Verified it with a call to the manufacturer that they have no plans or intentions discontinue either. ;) WD

    Bart, In a previous post you recommended V-133 for the PPC during cool/cold weather periods and the LT powders for warmer weather. Has your thinking changed on this subject? dedogs

    No V133 works very well in the winter. It just gets spastic in hot weather. But the LT powders will Work to.

    What would you recommend for a 'summer' alternative to N133. 'Summer' as in Phoenix so both hot and very low humidity at least until the end of June when the humidity gets ridiculously high like 25% or more. :)

    6BR, -0.100" so PPC case capacity, 65 -68gr bullet.

    Maybe with these new powders someone should revisit 6br on the short line.

    They do it all the time. Somebody is shooting a br or variant at every big match but they never win on a regular enough basis to turn anybody. Theyve been doing it for over 20yrs that i know of and have never won a major match

    I have not had consistent results using 66-68 gr bullets with either LT30 or N130, in a 6ppc. Rather than go into a detailed show 'n tell, after several sessions with each it appears both powders have a very narrow "tune window." Even with a tuner they'd shoot the lights out on one target, and ten minutes later I couldn't hit my a$$ with both hands on the next! :( Additionally they both acted "spikey," which is (state of) Maine-speak for quick to over-pressure. That showed up with hard bolt lift, flat primers, and chronograph readings that were all over Hell-and-back. I gave it up and stayed with my "goto" IMR 8208 load.

    A season or two ago another posted had great luck with "LT31" in a 6PPC. As you might suspect, it was a mix of LT30 and LT32. Not one to poo-poo (as in ridicule, or dismiss - not a #2 :) ), something without trying it, I bought a pound of each and had at it. Initial tests went well. Somewhere around 28.0 grains of a 50:50 mix gave about 3,380 ft/sec and no extraction problems, but the chronograph numbers weren't great. Less than 28 grs had worse numbers, and even a little more gave bolt click. On an IBS 100 yd score target in mild conditions, the load would just drive a couple for X's, and then throw the next one for a "hanger (down south called a "line-licker") 10!" Another session with it about a week later gave the same results, so I threw in the towel on the effort.

    Both of these powders appear to have identical sized grains. For the two cans I had the only difference I could see was the LT30 grains were shinier than the LT32 ones. For the mix I had put 2 weighed ounces of each in an empty 1 lb powder bottle, which was then swirled and tumbled around by hand for about 5 minutes. Now, sometime after abandoning the effort I wondered if the blend wasn't mixed well enough. I took a small sample and put it under a magnifier. Lo and behold (!) it was easy to pick out groups, or clumps, of shiny grains and dull ones. A-ha! Inconsistent results are being caused by a poor mix i.e., some rounds had more (or less) of one powder, than the other. Easy fix . . . just mix the mix, longer! So I did that several times, checking the progress with the magnifier after each 4-5 minutes twirl, shake, and tumble session. Contrary to my expectation that the mix would become better blended . . . it didn't! In fact it didn't seem to change at all. The grains of one or the other continued to group together. I gave up at that point. The only explanation I could come up with is maybe the deterrent coating was causing the grouping together effect, but who knows. I don't have a rotary tumbler, so I didn't try mixing it that way. Someone who does and wants to give it try can. If so, please let me know what happened.
