Jordan, I'm probably way behind the curve on this, but I've noticed recently that spotting hits gets a bunch easier when I practice the whole 'Natural POA' concept, and don't force into any positions with my core, arms, head/neck, etc.
Of course, it's not great practice for hunting, but when stretching it out and shooting prone, it sure is nice to watch the good stuff unfold through your scope. Absolutely! It certainly helps when the rifle's recoil is straight back and on target, rather than bouncing the sight picture off target.

Bear with me as this is purely anecdotal, but as far as velocity goes, Pat and others report seeing 3000fps from the 130VLD and SAAMI .260 Rem, others are getting 2900+fps from the 140AM and .260AI, and the 6.5C factory loads show 2820fps with a 140AM, and 2950fps from a 129IB.

I'm thinking the useable difference in capacity is less than one grain between the Creedmoor and the 260, so what one will do, so will the other. Mostly an OAL difference.

It has been stated that the increase in case capacity difference is a mere 1% between the 260 and the 6.5 Creedmore. This is somewhat insignificant, case design aside. But, the increase between the 260 and 260AI is approx. 5%. But, to realize a gain a longer bbl. such as a minimum of 24" but better a 26" bbl. to gain muzzle velocity is desirable. Plus, if a person wants to load a 130VLD Berger or a 140VLD Berger a short action is fine as long as this is a bench gun or a single shot varmint rifle. My 260AI Rem. 700 Mtn. rifle sports a short action and a 24" bbl. My load consist of 130VLD Berger, 46.0gr. of H4350, seated out to just touching the lands. These loads will not fit in the magazine. The load is extremely accurate. I have not chronographed the muzzle velocity as I am more interested in accuarcy rather than velocity. If a person is truly interested in a 130VLD or a 140VLD perhaps he or she should consider a 6.5X284 with a grand increase in case capacity and screw on a minimum of a 26" bbl. Now we are talking performance. MTG

Scenarshooter, thanx for posting the pics. I have wondered about the case design of the CM. Looks to be a slight starighter wall and a greater shoulder angle. Interesting. MTG

I shoot a 260 Ackley out of 700 Ti short action. 130 Bergers feed just fine and the ogive is just fine for super accuracy. Out of a 22" barrel I'm getting 3,000 mv. Doubt the CM will get that unless it's a 26" barrel of which the CM needs the longer tube to get speed close to a regular 260. Does the 260AI have a velocity advantage over a 6.5 Creedmoor with 120-140 gr bullets?
Yes,

I am assuming that you must seat the 130VLD deeper into the case. Yes, just touching the lands is not difficult. Getting a 130VLD to fit the magazine, in a 700 SA, can be difficult unless you seat the 130VLD deeper in the case to allow for a length for magazine length. My first bbl. was a 260 in my mtn. rifle. I installed a Shilen 24" bbl. that has a custom chamber in 260AI. A much better arrangement. MTG

side note, my 700/260 with factory mountain contour on it will shoot will with the 140 Bergs to fit the box but not the 130 Bergs...ah it never ends does it...grin

Having a 6.5 built now and considered the Creedmore, 260 AI and the 6.5-284 but in the end went with the 6.5x55 AI. In my mind it seems the Swede was in the middle of what the others can manage.

I guess I was referring to factory chambers when I mentioned a Creedmoor as a better fit in a Short Action. I used to have a 700 Mountain Rifle 260 that wasn't close to rifling with a VLD at mag length. If I ever have another short action 6.5 screwed together, I'll probably just go short throat 260 and call it good.

Pat,
What are the options for 6.5 Creed brass?

Hornady. I find their 6.5 Creed brass to be very high quality. I've used a lot of 6.5 Creed brass to make 6MM Creed brass for my GAP 10.

Cool. Thanks.
So the Creed probably isn't the best option for a rifle that a guy plans on using in situations where he'll likely lose a lot of brass, hey?
If I lose a few RP .260 brass in the grass, it's no big deal.

You could always use Mule Deer's Cream of Wheat fireforming method with 22-250 brass.
