[QUOTE="benchracer, post: 1023213, member: 22069"] I normally prefer H4831 and RL-22 for my Swede, but I am using a 26" barrel. My thinking is that the RL-17 might work slightly better than the 4350's for this because of its shorter pressure rise time, getting better performance from a short barrel. If RL-17 doesn't work out, RL-22 or IMR 7828SSC might be worth a try. ETA: According to QL, if loading to a MAP 55,114 psi, IMR 7828SSC is ideal, reaching OBT @ 1.075ms for an 18" barrel just below max with 98+% load density. RL-22 does the same thing at 101% load density. RL-17 reaches OBT near max, but around 88% load density vs 94% for H4350, so I can see how the 4350's might be preferred in that burn rate range. However, the 4350's produce quite a bit less velocity, so it might be worth it to see what real world results actually look like before making the call. [/QUOTE]
