Re: 162gr. A-Max and 284 Win
You didn't read me wrong...I did get 3100 in my 23" 284 win with molyed 162s but I they didn't shoot well with that much powder.
I want to also clarify that I seat all bullets close to the rifling or as close as possible with my 3.1" magazine.
In the past I had tried the 162 A-max with H4350 and most accurate was 55 gr with a molyed bullet. Velocity was right at 2900 fps. After considerable testing and minor tweaking of seating depths and powder charge I determined the rifle would not shoot the 162 A-max accurate enough.
I got similarly bad results with the 168 Berger VLDs. 55 gr of H4350 yielded 2860 but the bullet was not near the rifling due to it being so pointy.
Enter RL-17. I tested the 162 A-max, 168 Berger VLD, 150 nosler ballistic tip and the 140 nosler ballistic tip for pressure and noted accuracy. I didn't think thethe A-max or VLD would now shoot but was curious as to pressure. I thought the ballistic tips would shoot. I intend to buy a custom reamer throated specifically for VLDs from Pacific one of these days and was mostly interested velocity increases.
168 molyed Berger VLD and RL-17:
53 gr was 2816, 54gr was 2867, 55 /2945, 56/ 2990, 57/ 3025, 58/ 3075 Seems like 58 gr is too how based on the higher jump of velocity compared to the 57 gr load but I didn't not notice any pressure. @ 50-60 degrees
56 gr 3015, 57/ 3070, 58/ 3115, 59/ 3145 with signs of pressure. @ 50-60 degrees
150 nos bt
57.5/3125, 58/3150, 58.5 3175 no signs of pressure. 58 was most accurate @ 50-60 degrees
140 nos bt
58/3250, 58.5/3275, 59/3300 , 59.5/HOT load, leaky primer...accuracy was not that great but I didn't try any tweaking. Old 140 loads with H4350 was approx 3000-3050. Temps were 65 or so.
I liked the 150 nos bt accuracy best so I tweaked it. All original loads were with 55-60 temps max. Then it got hot the last two weeks hitting 85 when I shot. The 58 gr load's velocity increased to 3185 and the groups opened up a tad, So I backed down to 57 gr and it was the most accurate from 55-85 degrees with velocities at 3100 fps.
I had to go back to my loading booklet to get the above details. Hope this helps clarify stuff. I cannot recommend charges you should use with non molyed bullets.
I hope you get some good results.
