My apologies for misreading your question. RL15 is a ball powder but it seems RL17 is a extruded powder. I’ve never used it. Give us a range report when you get some loaded and fired. :)
Might want to check, but pretty certain all the RL series is extruded stuff. 15 certainly is, as I sit here looking at a cap full.
Yes sir. Should get the new powder sometime next week. Will test rounds next weekend.
Loaded H 4350 into Hornaday brass with Accubond 140gr bullets. 3 rounds with first shot cold barrel. Sub 1/2” moa at 88 yards.
Same brass and bullets with RL 15 was almost a 1” mod at 88 yards. One round could have been a flyer as first two were a two shot same hole at 88 yards.
Still haven’t gotten a ship date on the RL17 but my Lapua brass should be here Wednesday. If the powder comes ill load up some rounds and test this weekend. If that powder works, apparently is more temperature friendly, will be a good thing. If not I may have to find someone who wants it.
