Re: Tried RL-33 in three different chamberings today
Iron Worker: I would imagine you would be in the 3500 fps neighborhood. I would certainly work up to the max I used.
I said I wouldn't do it but today I tried some RL-33 in my 300 RUM with the 230 gr target hybrids.
I have a nice 27" lilja SS but unfortunately it has a 1 in 12 twist. I wanted to try the 230s a while back so I rechambered a 24" 300 win mag ss Rem takeoff. I had a load with 88.5 gr of H1000 vel 2860.
Didn't change anything except the powder. Started with 90 gr and worked up. Temperatures were 85-90 degrees. Here are the results so far:
94gr no reading cardboard shades moved had to wait for next ceasefire to adjust
98 gr 2925
No signs of pressure, no bolt lift issues, primers look good etc. Will start when range opens and temps are in the low 50s. Will chrono the 100 gr load again for comparison. FYI the chrono was working perfectly the 308 and 284 shot the same velocities as the last few times.
Will report back tomorrow.
