LT32 vs Benchmark vs XBR 8208 vs N133 temperature sensitivity?

[strow]

How does the temperature sensitivity of LT-32 compare to N133, Benchmark, or even XBR 8208?

Are there any positives or negatives to the LT-32 over the others listed assuming the barrel like it? Fouling? Forgiving to tune? Metering?Specifically loading for 223R and 223AI shooting 40-53gr bullets.

Is XBR 8208 a little on the slow side for the 40-53gr bullets in 223/223AI?

IME with those powders, but in a ppc/6 Grendel, no question, the LT32 is less temp sensitive than n133. BM is a very good but a bit inconsistent between lots and 8208 is great but pressures out a little before i'd like velocity wise. Keep in mind, different cartridges can yield different results but I think you'll find similar results. LT32 is just a hard to beat powder, all around but all you listed are very good.

What I should say is the rest are all junk and I can dispose of them for the shipping. Lol!

8208 XBR is fantastic for light bullets in 223, 243, and a bunch of 22/6mm cartridges.

Thank you both for he reply! I have XBR on hand and will pick up a jug of LT-32 and see what tunes up.

8208XBR is amazing in my. 22BR with heavy bullets. Not temperature sensitive at all. As good as Varget in my experience.

If you like the way 8208 meters, you're in for a treat.

I tried 8208 in a straight short range 6BR; worked well, but seems kind of peaky as you had towards higher pressure loads. Made me a little nervous (not that I shoot hot loads much.) LT-32 seems (to me) to much more linear with the spicier stuff.
