[QUOTE="CA48, post: 2752358, member: 21446"] H1k is much more temp stable than rl33. My buddy ran rl33 in his 28nos with excellent velocity and accuracy. 195s at 3050 in a 26”. But when summer came around he changed to retumbo at 2980 for better temp stability. Where we are it may be 75* in the morning then 105* by mid afternoon. We shot a his steel course for 2 days in the summer and it was obvious the temp swings were affecting his rl33 load, also confirmed it with the lab radar. Rl33 can also be hard to find. I keep some around but rarely ever use it since I can use n570 with equal velocities in magnums and it’s very temp stable. Also I think Cody is right, rl33 is to slow for a .338 case that size with 250gr bullets. H1k or retumbo will work well and get good velocitys. It would seem rl33 is best suited for larger cases using the heaviest for caliber bullets. [/QUOTE]
