58-75gr projectiles in 6 Ceedmoor?

[Huntinglife]

Has anyone ran 58-75gr projectiles with a saami 6 Creedmoor chamber? If so how did they do in it? I'm worried about the .183 freebore being too much for that weight range. I am looking at putting together a new coyote gun and wanting something flat shooting with more knockdown than the 223. This will be a 1:8 twist barrel 18" long and running a suppressor full time.

If that's the only grain weight you want to shoot then you can also run the .109 freebore. Otherwise though I don't think it would be too much of an issue. They'll just be jumping a bit

I was also wanting to shoot up to 105gr. projectiles in the off season with it. I only hunt coyotes 2 months of the year and would like to be able to use it for deer season and long range steel during the other parts of the year

You might be surprised at the 105's performance on coyotes if you don't hit larger bone structures or the stomach.

I shoot the 105 Hybs in my 24" 6CM @ 3188fps. They CRUSH coyotes out to 921 yards so far. Anything under 700 is like cheating with them. Dumped two of them 2 weeks ago. 585 and 888 yards.

Load some up and try them.

They'll either not mind the jump, or they will.

Personally though I'd say why bother? The 105 hybrids are a great bullet. The 108 Hornadys (for coyotes at least), are even better.

 

[Creedmoor shooter]

I can assure you the 105 bthp from hornady is very violent on critters. Not the best bc but they shoot very well

The purpose of the lighter bullets is because it will only be for night hunting with thermal. At night with thermal you have no depth perception and have a really hard time judging how far away they are, so the flatter shooting the better. If it was for daytime then yeah I would just shoot the heavier projectiles and dial for drop if needed.

My Ruger Am-Pred shoots 70s very well but 112s even better. I haven't tried anything lighter than 70 yet but do intend to try the 65vmax.

My 6mmBR, 8 twist, has a .150" freebore. The 55gr Ballistic tips shot fast at 3,500fps but weren't the most accurate. However, the Berger 65gr BT shot under 1"at 400yds once I get settled in on a good load.

Any idea what velocities you were getting with the 70's?

 

[DLJ6]

Sorry, my memory failed me.
Now that I have my log book in front of me I see that they were 80grn hammers over 45.0grns of RL-16. And I didn't clock them. I do have some old Berger 71grn MEFs over H4350 and Rs Hunter waiting to test and 62grn Barnes over IMR 8208.

I use 69 Absolute Hammers with my 22" suppressed 6 CM thermal rifle, they steam along at 3850 fps, 400 faster than the 80 TTSX

I use a rangefinder & can easily point & shoot out to 375-400 yards with no holdover

Holdover is difficult at night with no idea of the exact size of the target

Thank you. Thats a nice load for night hunting. Just what I am looking for. How do those group in your rifle? Also do you know what freebore your chamber has?
