[QUOTE="GrayCreed, post: 2335223, member: 114633"] I have bad ejector marks at 41 grains in Lapua brass with the 140eldm, I was able to run the 143eldx up to 42.9 before hitting ejector marks in Peterson brass. My sweet spot for the 127LRX with h4350 is 42.6-42.7 (Pete brass no pressure). I'm just as confused as you are man, also I haven't found a load yet that will shoot the 147 without the brass seizing in the chamber. However I found that shorter OAL seemed to yeald less pressure. Also IMR4451 (very close to H4350) has got me the best velocities without pressure signs in 6.5cm. for me 4451 at 42gns was good behind the 143x and very consistent. However the h4350 was easier to get low SD/ES it hits pressure sooner (in my experience). 4451 was slightly harder to find the low SD/ES but not impossible, totally you can get SD of 5-10 from 4451. Oh I forgot to mention Reloader16, it is magic. Slightly harder than 4451 to find consistency but Reloader16 likes WLR primers. WLRs make Re16 almost as consistent as 4350. Also, Re16 will show big pressure signs QUICK with magnum primers. Also better luck finding Re26, Re23, H4350, imr4451, retumbo and h1000. ... Re16 is the hardest powder to find. [/QUOTE]
