Anyone in Canada build one of these yet? Pushing a 140 grain bullet 3000fps and change with better barrel life than 6.5-284?? Feeding from AICS or AW mags with no issue??
Looking for any info, good, bad, pros, cons,
Build it on a short action with ARC mags??
Use readily available 6.5 X 55 Lapua brass to to fireform.
Any help or guidance would be great.
 
I looked at that cartridge myself. IMHO it doesn't have much if anything over a 6.5x55 when loaded to similar pressures.

I load the 6.5x55 to similar velocities in my Tikka T3 using Lapua brass and don't see pressure signs. The powder I use is IMR7828SSC over CCI250 primers. It's very accurate and I've reloaded the brass a half dozen times. I use a Magnetospeed to measure velocities, which average around 3000fps.

The Addiction seems to be designed on the Ackley Improved system. As such there isn't IMHO enough powder capacity increase to make much, if any difference over the parent cartridge. That very sharp angled shoulder is designed for SLOWER powders and may marginally help to increase velocities.

Now please don't let me dissuade you from building or rechambering your rifle to this cartridge. The one OBVIOUS benefit is that you don't have to worry about the cartridges getting inadvertently put into a M96 milsurp.
 
Assume you were watching the 6.5 Guys vid with Scott Satterlee?

Interesting wildcat.. certainly not new.. but nice to see interest in "long and skinny" again.

The biggest limitations on this option is the action and mag. The generic Rem 700 and clones run into functioning problems when a cartridge approaches 3".... the Sweedmoor is better at 3.15" or there abouts.

AICS mags really don't want to work when the OAL approaches 3" .... and a Long action mag is too much of a good thing... and not enough of what you need.

If you listen to Scotts discussion, you hear a hint at a 3.15" AICS type mags. yep, the mag fed ELR game changes with the creation of a mid length mag.... and so does the choices in actions.

But that is a story waiting on a part....

If using generic 308 AICS type mags, I wouldn't bother with the Sweedmoor. The 260AI is already pushing everything dimensionally... and you are really within spitting distance of performance.

Bore life will be "short" with accuracy starting to get tired around 1000rds... run it hot and it might be around 700rds. No, the Sweedmoor will not be any better then the 6.5-284 for bore life.

If you need the performance, then go for it..... horsepower is neither good nor bad. Just match the gear to the tasks and enjoy...

3.15" AICS mags changes ALOT of things.... Can't wait to see what gets announced at SHOT2018.

Would love to meet Scott and pick his brain about how he has his setup and running.
I have a 6.5 creed right now and the Lapua brass cost me 145 a 100. 6.5 X 55 Lapua brass is a little cheaper and seems to be more readily available and if a guy could gain 200 to 300 fps over the creed I think I would definately be interested.
Would however need to definately feed threw 10 round box mags so that may be the holdup.
Thanks for your input. Greatly appreciated!
 
I am not sure there is much advantage for me to retool, redie, acquire new brass, do a new load work up with this from my 6.5 Creed?
My go to load with my Creedmoor is running 140 Hybrids at 2960fps, with great SD and ES off my Labradar, so to gain 40-50fps seems pretty marginal to me. Plus cost of another barrel etc, seems like an answer not needed. I’m not an expert or anything, just genuinely curious to real world advantages?
Be curious to hear guys input. I love my Creedmoor and am on my 3rd barrel, on order, but am just starting to play with my new GAP 4S 6.5 SAUM, and it seems to give the 140gr an extra 200-250fps over the Creed with the same or even a bit better barrel life over the Sweed. Would this not be an easier and overall better next step up from the Creedmoor?
(Again, absolutely not picking on that caliber or saying it’s wrong at all, just intrigued by guys choosing it over other calibers and curious to hear their experiences).
 
I have run the 6.5 140's at 2900+fps for a few years when I shot F open. Wonderful, wonderful ballistics. The combo is simply deadly on target so I totally get why combos are trying to get to this node... it simply ROCKS BUT, it is hard on bores. Does that matter???

Problem is packaging. I was single feeding, long throats, toasty pressures BUT it worked cause my set up wasn't going to need to run fast.

When you start pushing small cases hard, you can easily run into pressure related functioning problems. That extra push to get the bolt open costs time and for the intended application, can cost a stage. I run my 6.5 CM at print load data and it is pretty toasty already BUT extraction/ejection is a no brainer. 2700fps is where my loads are and I see no point in pushing it harder.

Is there a difference in LR ballistics vs the same bullet going 2900'ish? Of course, but is it really that big a difference? Run a comparison in ballistics and decide for yourself. I have shot my 6.5 CMs out to 1450yds in moderately heavy winds. yes, you have to hold more into the wind but if you know your drift, know the wind speed AND have a load that is well tuned... it is merely a number.

Could going faster give you a few more hits on target? Maybe but if you are spotting your own impacts well, that first miss will hopefully give you all the info you need to adjust your dope??????

Now the functioning differences... currently, the 6.5 CM will live in a 10rds mag... the Sweedmore, RSAUM, PRC will not. This I feel is a big disadvantage

So the debate is speed vs capacity. What ends up gaining you more hits over the match????

Obviously, new mags will change this debate...

Given that most matches I have reviewed spend far more time inside 800yds vs beyond, I don't see the advantage of the speed vs higher bore wear and possible lower capacity. In fact, there is an interesting post elsewhere to debate the benefits of a 22cal running heavy bullets going fast... recoil reduction and speed of recovery is becoming a far bigger need at some events.

Scott shoots in the NW were winds can be very high... I expect part of his reasoning is to help tame the massive drift of smaller combos. Shoot where winds aren't so insane, and you may not see the advantage.... or even the need for anything larger then a 6mm.

Now if you were to compete in ELR matches where a high percentage is 800 and beyond, lower rds per stage, little to no barricade stages, etc, etc, then you could make a wonderful case for more speed... or a larger combo.

I don't think there is one answer as the event tasks can vary so much.... I would try and get a feel for the course of fire and see what is likely the best combo....FOR YOUR CONDITIONS.

All very good points Jerry, thanks.
I’m not doing any PRS stuff, just trying to shoot little groups and bang steel way out there.
I do get the “fit in the mag” approach for sure. I’m happy if mine fit in the Mag, but single load for what I do is no problem either.
The Sweede just isn’t my best fit then, and probably neither is the GAP 6.5 going to give me tons over my existing Creedmoor, it enjoy the work up process.
I do love my 6mm stuff too, and my 6XC is scary accurate and so easy to shoot all day, so get why lots of guys are gravitating towards them as well.

Click to expand...

Given your intended use... I would bypass the 6.5 AND 6mm completely. Build a long barrel 284 Win and understand why F Open at 1000yds is void of smaller cals.

I think you will REALLY like this combo and bore life is double the fast 6.5's....

Accuracy potential is fantastic... my game is to hit a 5" circle at 1000yds as often as possible. I assume your gongs are a wee bit bigger :)

Let me know if I can help...

Great input Jerry from @Mystic Precision. I do live in South Sask. and it tends to always be blowing 25 to 50 km/hr...or so it seems. Decisions decisions
