RL15 for 243 with 80 GR nosler ballistic tip bt

[airb080]

So I recently added a 243 to my stable. I have had pretty good success using 44.3 GR of IMR 4350 loaded in hornady cases using CCI br primers with a COL of 2.683. This combination has been grouping in around 1/4 to 3/8 in. I'm almost out of the 4350 and was wondering if anyone has had any success with RL15. I usually use RL15 to load for my 30-06 and it performs great for an old savage 110 with 3/4 to 1" groups. I found some load data from Lee for 80 GR jacketed bullets but not sure if I should spend the time trying it as I have never heard anyone else using it. Also has anyone tried using H335, I know it's good for 223 and 308 but haven't found anything for 243.
Thanks for any input.

I'd stay with 4350, but I've been a big fan of Reloder 15 so it would not hurt to give it a try😉.

Yea, I've been kicking around the idea cause I have about 6 #s of it. Out of all the powders my 06 loves it, not so much on the 4350, but the 243 gets good groups w/ 4350.

Powder won't fill case as good but should be OK.
