OK, I will bite. Why do you mention factory guns specifically?

Mine is a Bartlein 28" tube. What should I plan on?

Factory guns are held to SAAMI spec which is proven dimensionally safe across a wide standard of usage. You may see some pop up into the 2900 fps area safely but don't expect it.
The guys you see getting the best performance with 215s are running purpose built rifles with chambers specifically for an intended use.

If it's a standard SAAMI chamber, expect 2900 fps. Consider it a cherry on the top if you can safely push higher.

This thread makes me happy that the barrel I ordered (and have not received yet) I listened to Jim at NSS and got the "match" chambering. He said it will work perfect for the 215gr and above bullets.
I almost didn't listen to him because I want to feed from the mag most of the time. I think it will all work out good. My bottom metal is coming with AI mags which appear to be longer than a factory mag.

Please explain match vs saami chamber...what is exactly shorter or longer?
I have a stock 700 sps and getting 2830 with Hornady brass and I think 76.5 gr h1000. I feel this is about as far as I want to push it, accuracy is good and brass life so far is good( five firing and still good primer pockets) no pressure signs
Beeman thankyou for the info. It appears that this comes down to the brass and weight sorting as well as brand of brass. Also can you tell me how to get in touch with Broz.?? Do you have a email address or phone number. You have my interest about the reamer he recommended to use for your barrel. I will be having a 300 win mag built next month hopefuly. It will have a 26" brux barrel. If i cant get 2900 fps or better using 215s, there is no point to me in switching from the 210s i now use at 2950 fps.

It's longer. I just looked through my notes from when I talked with Jim at NSS. I did not write down how much it is longer by unfortunately. He said if I'm only going to be shooting the 215gr-230gr bullets I'll definitely want the "match" chambering.

That is a large difference between the "Match" and the "Tactical Match" freebore.
