SHAWN i have 6/284 dies if u need them form/full/seating-----steve sldimon@roadrunner.com thank u
I use IMR 4831 with the 87-88gr bergers. Start around 47-48gr and work up. Gonna try Hybrid 100V but too busy shooting yotes with my new to me 20/222

4831/760/N160...You'll end up with about 80-85 % case fill with speeds (give or take 100fps) around 3450 ish with Max loads of 51-54.5 grs depending on powder an lots. Slower powders will not give consistant velocities as they don't get a good pressure curve in the 24'bbl with the light bullets.
This Quickload predictions might or might not help you but I'll post them anyways.
The following loads generate 58,000 psi and/or don't exceed 107% case fill so they should be considered as MAX or NEAR MAX.
---------------------------------------------------------------------------------
Cartridge : 6-284 6mm/284 Shehane
Bullet : .243, 87, Hornady V-MAX 22440
Useable Case Capaci: 62.455 grain H2O = 4.055 cm³
Cartridge O.A.L. L6: 2.800 inch = 71.12 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 58000 psi, or 399 MPa
or a maximum loading ratio or filling of 107 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
62 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

They're just about the same thing if I'm not mistaken. Minor differences, and if max charge weights are reduces 10% and worked up accordingly, then it's safe to use the QL data I posted.
