800y, is the 6CM have anything over my 65CM

[philcox]

I currently have a 65 CM, shooting the DRT @ ~2800 fps 21" TIkka. I "want" a gun/load combo that COULD do 800, and that I could use in Cali (so Mono). I also want a short barrel (current one is as long as I want). Current load is good to ~600y. Doing all the number crunching I can, I am not sure if I can get the 95g DRT to 1800 fps at 800y.

Real question, and I think I know the answer is: Does the 6CM buy me materially anything over my 65? Given my limitation of the DRT and the desire for a "short" barrel, seems that I can't have both. If I want the distance, I need the barrel length.

Any thoughts are appreciate. Still trying to think this through.

Well, in these two instances I doubt it. The BC if the 95gr DRT isn’t high enough to over come the 135gr 6.5mm, even with a higher MV. They’ll probably end up at about the same range. The 6cm is easier to shoot/spot with though.

If you need to use a mono, you’re really looking at a 22CM with the DRT 79gr, or a 6 PRC or 6UM to get terminal velocity to 800 yards.

Never thought of the 22CM. I’ll look into that. Looks like it’s legal for big game in pretty much every state I would hunt in too!

Yep. You should get 850’ish yards to 1,800fps impact with the DRT 79gr.

I was debating between going from 6.5 to 6 or 22 for my daughter on her Sig Cross. In Montana there's no caliber restrictions. She's got a 16.5" 22 Creed pipe coming.

What kind of barrel did you go with?

Do you reload? The 93gr copper rose has shown in video testing online to perform very well on big pigs, believe Tyler Freiel(spelling?) killed pigs with his 6cm and that bullet at long distance with great results. The g1 is stated at 0.500, I believe this is one the sleeker 6mm solid offerings. I know solids catch a bad rap on here, and it's been earned, but some the newer solids do expand/frag/tumble a lot better than a Barnes. I know of a few guys in our shooting circle that used them successfully on deer/elk last season with very good terminal results.

I do reload. I'll do some research and check them out.

The BC is nowhere near .500, and terminally the are variable. I had good results at 3,000+ fps impacts last year on two animals, and Ryan had extremely poor wound channels and several hundred yard recoveries on two pigs from lung shots.

Man, that's unfortunate to hear! Saw good results on those pigs they shot in Cali. Nothing beats lead unfortunately.......why can't these guys making solids get some accurate BC values published?
The hammer guys spit out a numbers that they verified at unusual 3600-3900mv, who the hell runs 85gr capacity 6mm and 100gr capacity 65mm cases? VERY few people.
The only solids I've personally verified at or near published BC are the cayuga from PVA. They shoot very well and are slippery but terminal performance isn't what I want.

22cm is a barrel eater. Keep that in mind if you plan to plink with it at all. I only got 800 rounds out of my last barrel.

What powder? Rapid shot strings?

Varget. Not rapid, hunting yotes and pigs

Apparently McGuire has sent their bullets to Hornady for radar verification of actual BCs, still waiting for results.

After all the discussion here, and as much as I want an 800+ rifle, it is not in the cards for me. My order of evaluation is:

1. Proven bullet ... for the non-lead, I am trusting @Formidilosus with the DRT (and have one animal down last year, it went 20y, so it is a "semi verified" trust, not "defer to authority" trust)
2. Minimum impact velocity in my rifle ... which is 595 for the 135 DRT, and 495 79 DRT
3. Accuracy (using 18" on Elk, and 10" on Deer) ... 65 is ~ 1.7 (so 1000y on Elk, 588 deer), 223 is ~2.0 (so 900 Elk, 500 deer)

So at this point, my MER is 600y with my 65, anything farther than that, and I can't shoot. If I have the 223, then it is 500y.

I am contemplating trying to build a load for my 300WM (since DRT does not make a 7mm for a 7 PRC) to see if I can get something at the 800+ range. UPDATE: Looked at the 175 DRT and this would get me to 1000y should I need to go that way. Not sure if the accuracy would allow that though.
