as stated earlier, you should measure the headspace of a fired case (with RCBS precision mic or Hornady's headspace tool) from this gun and compare the measurement to factory rounds of all the brands you have available. If any gun has issues with firing factory ammo (especially Weatherby factory ammo because it consists of top quality components), i would have to assume there is an issue with the chamber/gun and would have a reputable gunsmith inspect it.

300 Weatherby loads for Remington 700 with 24" barrel
Hi all this my very first post on this forum,I actually joined this site because of this topic, First of all I have had my Remington 700 classic since 1989 and I have shot just about every type of 150 grain ammunition I could get my hands on and I may as well have shot a 12 gauge unchoked at 100 yards as I had flyers all over the place anything under 6 " was a decent group but all that changed once I started running longer and heavier 180gr rounds I used everything from Weatherby Nosler, and Remington, which all grouped really well my best being .66" 3 shot group 3"s high @100 yards.
So now I have just got myself into handloading just over a year ago with my Lee single stage breech lock system and ordered the Lee collet dies and Lee factory crimper .So I would lime to know where to start with loads to try some 165-168 grain rounds as far as powder selections that work well with its 24" factory barrel that would offer great velocity and accuracy with out undo pressure I have heard R22 and Winchester Supreme 780 are good starting points but I don't really don't know where to start so any useful info is greatly appreciated.

For those of you who say you never have to re-size the 300 to the belt, let me tell you what happened to me.
A few years ago, I had the problem, after full length sizing with an RCBS die, of not being able to chamber loaded rounds. They didn't chamber because the die was not installed properly but rather, because the die didn't remove the bulge directly above the belt.
I took my Mark V and two re-sized cases, that would not chamber, to a reputable gun shop. I demonstrated the problem to the gun smith. He pulled a used 300 Mark V from his rack and was able to chamber the two cases without difficulty.

thank you
Allen J really Winchester 780 has been discontinued? Thanks for the heads up ,how do you think 7828 reloader 22 will burn in a shorter 24"barrel how about reloaded 25 or retumbo?I have heard from a friend who has been handloading longer than I have been alive and he loves reloader 22 as well .

I'm going off what the Midway website says (do a google search for "midway winchester 780") and by what a local gun store owner told me. I still have a pound and a half of the stuff and really like it, it did very well in my 7WSM with 168 grain bullets, but I can't see working up any new loads with it unless my information is incorrect.
The only difference you should see between a 24" and 26" barrel is a small drop in velocity, like 30-60 fps. I've never used R25 or Retumbo but have read good reports from both.
