Currently shooting cutting edge 350gr mth with 128gr retumbo in a 28" 10 twist barrel close to 3000fps, I know I can stuff more powder in there but its working and I'm smiling at the range. This load is holding 0.66-0.75 MOA to 1500yards. Now I'm down to my last box of 50 bullets to reload before having to buy more. I like buy 4-500 at a time so the lot/milling batch is the same, the 350mth fit nicely in a magazine for the odd time that i want to send 5 quickly down range for the grin factor of making the gongs dance. Do I stick with the 350gr or go heavier chasing a better BC and design to push to longer ranges.

Looking at something still by cutting edge because they are somewhat readily available up here. Probably close to the 400gr stuff if they actually fit the chamber properly. Just wondering if they will actually fly that much better/hold energy and stability and be that much more forgiving with wind calls.

Unless someone else projectiles are easy to come by. Hate trying to get "special" order stuff due to wait times and import fees
 
The bergers look nice. But I think the limiting factor will be when well we see them north of the border. Figuring probably September/October that they might start trickling up north.

When looking at cutting edge BC charts and comparing against Ko2M results, the lasers are used the most with them having the lower of MTH/MTAC/Laser BC comparison of same bullet weight for the 375cal. I guess I'm wondering how real life differance of a G7 BC of 0.415 vs 0.48 make?


Haven't found the spot yet that I can hit super far, 2000+ yards consistently yet without skipping bullets down gravel roads and not having 4-15mph gusting cross winds. Not enough farm fields close enough to play in. Have a couple spots that are getting 1400-1600 yards reliably.
 
I shot the prototype bergers they are worth it. Until they become more main stream the Cutting edge 400 g lazers are insane had a es of 8 4 was regular.
 
I am just about to start load development on some 400s as soon as I have brass. When I was deciding what bullet to go with I talked to a bunch of experienced ELR shooters about twist rate and bullet weight. What 1 was told is the 10 twist will not stabilize the 400 class bullet. You probably could go to a 375 class bullet but might still might have issues. with the current barrel you are probably best off to run the 350 bullets until the barrel burns out then switch to a faster twist. I ended up going with a 7 twist on my Cadex CDX-40 shadow. i Know Ken at Bulls Eye London should be seeing a massive shipment of Cutting Edge bullets very soon, was shipping today from US.

Looking forward to your report Ryan. Why the 7 twist? Just factory offering? Wonder if the 7 twist will increase pressures and make things a little more difficult? Would a 9 twist be ideal as most 400gr class recommend it or something like a 8.5 to play the "just-in-case" card
 
Tried 350gr lasers last night with 139 to 141.5gr N570....the 140gr produced about 2inch group at 400yards with velocity around 3236fps. Loaded to seal tite band. Primers were pretty flat in all charges, thinking of dropping down to around 134-137gr N570.
