[QUOTE="elkaholic, post: 1333456, member: 13833"] With the recent success with WW Magnum primers and RL26 with the 215's, I thought it would be a good idea to revisit the 285 ELDM. I figured it would help the slow for bore powder to burn a little better and build pressure a little more normally. I never dreamed of using that heavy a bullet when I designed the Sherman but it is looking like it might be an excellent choice for some applications, providing they will group. I will try that down the road. Today, I loaded some Norma cases with 67, 68, 69, and 70 grains behind a WM primer at 2.544" coal and strapped on the magspeed. I also loaded one round of 69 in a RWS case. I did not get a reading on the 70 grain shot as the bayonet slipped a little so the shots are as follows on the screen: (1) Norma/67 gr. (2)Norma/68 gr. (3) Norma/69 gr. and (4)RWS 69 gr. Nothing was over max, including the 70 gr. load which would have been just below 2700' it seems. At 2700', that is a little over 4600 ft. lbs. of energy from an '06 sized case. That is a whole lot of pop! [ATTACH=full]79268[/ATTACH] [/QUOTE]
