Anyone shot either the new RL10 or Hodgdons Benchmark? I was going to pick up some new powder to try. Couldn't find RL10 locally, so I may order some of it.

I thought someone had posted some results with these two in the 6x45 or 6TCU. Benchmark looks simmilar to H335 and H322. Anyone know if it has the muzzle blast like H335?

Gary I have burned em both in my NEF .223. They are both darn good powders and burn much cleaner than W748. Cant help you with the muzzle blast question.

RL-10X works well in the 6T/CU. I don't have the data with me right now but I started at 23gr and worked up to max. The fps at max from my Bullberry was 2900fps with a 70gr NBT. I'll look the exact data up and get back with you.

It's been a few years but I used Hodgdon's Benchmark in the 6mm T/CU. 55gr. through 80gr. Bullets worked quite well.
