Which powder would be better suited for 180/184 Hybrids out of a straight 284?
Which powder would be better suited for 180/184 Hybrids out of a straight 284?
That is like saying "which is better in the .284 with 180 / 184s H4350 or H4831sc?" RL-16 is very close in burn rate to H4350 and RL-23 is very close to the burn rate of H4831sc. Unless and until you try both in your barrel, you won't know which is best for your rifle..Which powder would be better suited for 180/184 Hybrids out of a straight 284?
Start at 53.0 and work towards (depending on your barrel and freebore) 54.6grs (in that vicinity) with RL-23..Start around 51 and work up with RL23?
I have found that up to 55.0grs (during load development) I had no bolt lift issues, no pressure signs and primer pockets were just as tight as down at 54.0grs. My load ended up at 54.4grs of RL-23 in my last .284 with 180 Hybrids. My neck and freebore were exactly the same as yours..How do the pockets hold up at the top end? I’ll use my 3x fired brass so I don’t potentially trash all my fresh prepped brass. I have fairly large freebore (235). 313 neck. 9 twist. 32” blake barrel
will give it a go and see how it stacks up against H4350

If memory serves me correctly, I was at 2860f.p.s. I would have to go back 3 years in my notes to find out exactly what the velocity was>>>but it seems to me it was right at 2860..Velocity node at that powder charge?
Your targets look to me like at that 2850-2865 (same velocity node as mine) shoots very well. You are just doing it with about 1+ grains less. My bet is, is that your barrel is about 1 thou "tighter" than mine was>>>>well within SAAMI spec, just a bit tighter than mine. That is my bet why your barrel is shooting at a higher velocity>>>> but your velocity node is the same..Well that was interesting test. 100 yard EC method test. 180 hybrid. BR2. RL23. Slight bolt click at 53.8. As you can see 54.7 open up bad. So I stopped there 54F outside today.
I’m using Norma brass. Hope pockets don’t get toastedYour targets look to me like at that 2850-2865 (same velocity node as mine) shoots very well. You are just doing it with about 1+ grains less.

Stay at the 2850-2865 node and you will be fine>>>worry not!I’m using Norma brass. Hope pockets don’t get toasted
