[QUOTE="Kiwi Greg, post: 704416, member: 13456"] I thought I would put this here as this cartridge is for ELR. I have been firing my 375 DCM, 375/408 Cheytac improved for a little while so I thought it was time I put some info up about it. The case was designed by a fellow Kiwi, [B]Rocky Mountain[/B], he also specified the barrel which is a 32" gain twist Bartlein 12-7.25. We had been waiting for these barrels for ages, they were supposed to be here before last Christmas....:rolleyes: She has an XLR HD Chassis, Barnard P-Chey action, 30 moa rail, Terminator muzzle brake, 5.5-22 x 56 NF NSX scope I haven't managed to shoot any great distance with her yet, the weather hasn't been helpful & the fact that my usual LR range is closed due to forestry operations....:rolleyes: I have decided to use the CE 425 pills that I asked Daniel at Cutting Edge to design & make for me in February this year, to use in the 375 Terminator & DCM. I will do more testing with the 375s & 400s but I'm very happy with how the 425s are going :) I haven't tested the BC of the 425 much yet but it did dial accurately out to 625 yards using 1.04 & I used 0.99 for the 400s out to 1700 yards in my 375 Terminator ( formerly Lil'Terminator) Here is a picture of her at the range. [IMG]http://i1004.photobucket.com/albums/af161/Kiwi-Greg/338NM375DCM008.jpg[/IMG] I have designed the T5 Terminator muzzle brake for it which works very well. [IMG]http://i1004.photobucket.com/albums/af161/Kiwi-Greg/338NM375DCM010.jpg[/IMG] I have tried a few powders in her & have decided that even though US869 gives me more velocity the temperature sensitivity, ES & accuracy aren't what I'm happy with, so I'm using ADI 2218/Hodgdon 50BMG. Here is a picture of a 338 Norma, 338 Lapua, 375 DCM, 425 Cutting Edge pill, 223 for size comparison. [IMG]http://i1004.photobucket.com/albums/af161/Kiwi-Greg/375DCM425CE010.jpg[/IMG] I am still only neck sizing my cases & they have been fired 4-5 times so far with very little head expansion :) Here is a group at 217 yards. [IMG]http://i1004.photobucket.com/albums/af161/Kiwi-Greg/375DCM425CE005.jpg[/IMG] Here is one with another grain of powder. [IMG]http://i1004.photobucket.com/albums/af161/Kiwi-Greg/375DCM425CE004.jpg[/IMG] As you can see she is showing heaps of potential, the ES is pretty good & should be able to be improved upon. We are happy with the speed & have been over 3100 but haven't settled on a load yet. More fine tuning to do to see what see likes at distance, good times :cool: [/QUOTE]
