200 grain Cutting Edge Bullets

[AKGuide]

Just got some C22's in to test in my 300 RUM. Just got my OCM done and need to fine tune the OAL for the best groups. I would be testing now but the wind is holding me up for long range testing.

Gun: Trued Rem 700, Pacnor 28" .338" neck, A-5 Mcmillan

OCW load (100.5 and 101.5 grouped the same):
Rem Brass weight sorted
GM215M
101 grains H870
OAL of 3.917 .025" jump
MV of 3210

Just need to shoot the .010" and .020" jump at range to see if the groups get better or worse. I was also told that these bullets may shoot better at range as they need a little time to settle.

So far the bullets really like my gun and getting them to 3200 was a breeze with my hoarded H870 and a 28" tube. More testing to be done and I will post the results. My final goal will to test these on brown bear this coming spring.

Concluded testing this evening when the wind got steady at around ten mph. Final load is:

Rem Brass weight sorted 271-273 grains
GM215M
101 grains H870
OAL of 3.912 .010" jump (typo on the first post)
MV 3210

24F
30.2 InHG
52% RH
211 ft

Shot a one inch group at 300. Two in the same hole and one an inch low. I am sure this was my fault and just messed up on my breathing. 21 total rounds to get it dialed in. The rest will be used on game only. That is after I get my elevation for 500, 750 and 1000 yards and to see if the bullets lose stability at longer range. All loads were kept against my skin to stay a constant temp as H870 is finicky in the cold as you know. I will post drops at 500, 750 and 1000 yards when I have time. Hopefully in the next couple months I will post results of performance on bear. Straight shooting.

Good info got any pics? I think wideners just sent me an email saying they have w870 in stock for 40$ per 8lbs. They arnt shipping to NY anymore so its all yours lol.

It's good to see another CEB fan & to see they are treating you as well as they've treated me. I'm running the 6.5mm's right now.. Just got some new production G-10 140 grainers to test in the WSM. Can't wait!


Keep us posted on your adventures. thanks,

Great to see the good results! I'll be pushing them through my 300 RUM as well in a couple of months.

Do you know about the 1000 yd range being constructed on the Parks Highway?

1000 yd range becoming a reality.

Here's the pic it slipped my mind yesterday. I have no idea about the range on the parks. I live in SW Alaska and do my shooting on the frozen Nushagak or on the tundra. I will post a pic of a loaded 240 SMK next to the C22 later for comparison.

[AKGuide]

Just for a comparison the 240 SMK is on the left and the cutting edge 200 (C22) is on the right. The 240 SMK is seated to the lands at 3.658 and the C22 is at 3.912 for .010" jump. I didn't show bullets alone but the C22 is 1.616" and the 240 SMK is 1.592". The 240's are HBN coated thus the color.

Is there no pressure band on those CE's

Are you talking about the SealTite Band? (B) I'm sure it's there, just inside the case neck.

 

[AKGuide]

Correct Outlaw6.0, seal tite band is inside the case neck, but you can see the driving band in the photo if you look careful. If I seated to cutting edge's recommended seating depth I would be jammed .080" or so.

Forgot the exact terminology, I use them too in a different caliber and have never seated them so deep as to not see it. I would assume it would bulge the neck a little

 

[AKGuide]

Yes it does but only just slightly. I made sure to check that especially with the tight neck chamber. I neck turn to .334" when loaded, but with the seal tite band in the neck it makes them .336" when loaded. Now to just look for a detachable mag box that allows 4" OAL and I will be set.

I understand your thought. CE states there is nothing wrong with it though... LTLR did it quite a bit, I just took ownership of a box of 6.5mm 140grn CEB's that are only .100 shorter than these .308 200's!! I would imagine i'll be seating the sealtite band inside the case neck too
