[QUOTE="Long Time Long Ranger, post: 379355, member: 505"] A couple weeks ago a guy was asking if it were possible to get 3200 fps out of a 300 smk without going to the chey-tac case. I can't find that thread and I reported you could not on a standard cartridge. But I shot an improved 338-378 wby last week that was easily clocking in the 3200's with a 300 grain smk. The case was blown out quite a bit more than my standard 338-378 case and the neck changed to 35 degrees. The neck length I think was .33. Other than that it was about straight walled. We worked it up to over 3300 fps shooting over two in line chrono's. This was the fastest I have ever seen the 300 pushed. So the answer to the guy who asked is yes but not with a standard cartridge. You have got to improve the huge 378 case. Also the guy had a 34 inch barrel. I am building one with a 32 inch barrel by elk season I hope. It was incredible to shoot. [/QUOTE]
