[QUOTE="AZShooter, post: 864578, member: 5219"] Back to loading. Generally RL-17 loads should mirror H4350 or IMR 4350 load data. RL-17 will surpass either in velocity with same charge weights. I'd suggest you start with RL-17 around 54 gr and work up to what your rifle likes without any pressure issues. I'd guess you will most likely end up around 56 or 57 grs. ---------------- I was going to respond earlier but didn't figure my data would be that useful, here is why: I have a 23" barrel with over 1500 rounds through it. The worn throat, moly coated bulllets and an OAL of 3.080" will most likely have my loads unsafe in your 284. I'll share some loads that I developed in the last few years. 139 SST 59.5 was most accurate @ 3258 fps 140 accubond 59.5 gr was most accurate @ 3240 fps 162 A-max 57 gr most accurate @ 3055 fps 168 Berger classic 56.5 gr most accurate @ 3030 fps ------------------------ When Bob Hutton worked with this case back in 1963 he came up with a standard with a 140 partition. 57 or 58 gr of IMR 4350 for velocity right around 3000 fps. When my 284 didn't have the longer OAL and I was using 140 sierras thirty years ago I also used that same formula. When H4350 came out switched as it is an extreme powder and fits better. Then moly came on the scene. I use Rem takeoffs and it helped deal with the fouling that those factory barrels tend to have compared to custom barrels. This barrel is pretty much shot out. Next barrel with have a custom reamer to my specs and I'll use dynatec borekote. [/QUOTE]
