CCI 200 vs CCI 250 in 30-06

pollo · May 19, 2013, 06:06 PM

Hi all,

I have been looking around online and have found that some people are getting better groups using magnum primers in their 30-06's. Is this common/safe in 30-06? If it is safe, have you experienced improved accuracy using magnum primers?

I've been loading for the '06 for 20 years. Never saw the need or tried mag primers. I can't remember any published data using them either.
If you try it you better reduce your loads quite a bit.

It's common and it's safe. Accuracy probably won't be any better in any particular load, but there's a chance it could be.

Well, I saw this on the internet. This guy (dmsbandit from marlinowners.com) was using CCI 250s in a Marlin XL7 30-06 (which is what I have) and received this group:

I was just wondering what you guys thought of it.

Not in -06, but .270WIN ...... When using ball powders like H414, I get more consistant muzzle velocities and lose less velocity as temps drop, using a CCI 250 instead of a WLR ..... I can't imagine it would work any different in the -06.

For the 50 or so grains of medium rate powder that the case uses, why subject it to as much as 5,000psi from the 250s. Use mag primers when the manuals recommend it - large quantities of slow burning powder.

Heck, I use 200s under 55gr of RL-19 in my 280 for 3/4" groups with 140 NBT.

I've used CCI200's in my 30-06 loading for quite awhile, because my loads feature IMR 4350, any brass, 150 grn Ballistic Tip from Nosler, and CCI 200.
In the only two rifles I load for, this load shoots easily 3/4 MOA, and when it counts it's as reliable as old yellar when it comes to killing deer, shot many deer with so for me no switching primers.
