I've been loading all my hunting (TTSX or TTSX) and practice loads (Hornady interlocks) using Federal 210 primers but because I just ran out I was wondering how much difference it would make to substitute CCI 200 primers in (have a couple of boxes) for the practice loads. I'm happy with my hunting rounds so I'm not going to make any substitutuions there.

I guess what I'm wondering, will I have to rework up a load to practice my shooting positions with or will the difference be small enough that I don't have to worry. That being said, it's still nice to have a accurate load,,,,even for target practice or hitting pie plates from the 3-4 positions I shoot from.

Also, how much of a safety concern would there be if I didn't change up the load. My practice loads using the Hornady interlocs are under 100% capacity with the federal 210 I've been using.
 
Primers are the cheapest part of the reloading process. I always try to use Federal Match Primers. I keep my eyes out for sales or bricks of 1000 ant stock up. Never had a misfire or pierced primer. Sometimes shipping on primers is a joke so I try to buy locally.
 
Try it. Switching primers can take you from a 'so-so' load to an outstanding load... and vice-versa. It can have a big impact on accuracy. Some primers can put you over pressure too but I don't think you should worry about that too much unless you are already at the top end for your load.
 
I didn't see a POI or group size change between 210s and 200s last year with my practice fodder of 41.5 gr IMR 4895 under a 168 HPBT Hornady match in .308. I ran out of 210s, switched to 200s and saw no difference. At longer distances or over a chronograph you might see a small change but if groups stay the same at the intended distance you can tell your OCD to frig off. Try it and see what you get.
 
Accuracy and pressure wise, not a significant difference.

The big and significant difference is in primer sensitivity. federal are more sensitive. If your rifle has a poor striker (say, with a shortend fall to improve lock time) you might find misfires with CCI in loads that were 100% with Federal.

Poor ignition is common in handguns. The solution is often a switch to Federal primers.
 
I find there is such little difference in primer brands that its not worth the discussion. Even Match primers don't do much. On a small cailiber such as .223 you may find a very slight difference in groups but on larger big game calibers I can't say that I've had any noticeable change in my groups to attribute to primer brands.

I had a load that shot 'okay' with Fed215 but it's consistency lacked. Sometimes good , sometimes awful, more leaning to a flier every group. Switched to WLRM and had a consistent sub-MOA load. Likewise, I have loads now that shoot well with one primer and if I switch to another, the group opens up. If your load is not quite there with consistency or accuracy, switching primers can sometimes make a huge difference. Some rifles/loads won't complain with different primers but some will.
