That seems a pretty stout charge weight to be starting at. I'd start pressure testing at about 120gr of retumbo. H50bmg about 4gr north of that.

 

Thank you for your advise Orkan. Do you know what kind of speed is reachable with those 425gr bullets ?

 

Not really. I run 352's out of a 34" tube.

 

Send me your gun info. powder, case length bullet, COAL, H2o of the case. barrel and twist and I'll run it on Quick loads. do you have any chrongraphed groups to 0 Quickload to with the primer powder and bullet combo

 

themannurse... enough.

I know you're having fun with quickload and all... but enough. First off, if neco catches wind of your constant dumping of info, they will contact the forum administrator and have you banned. (yes, it's happened and will continue to) Secondly, the software is meant as a guide only... nothing more. There is such a huge disparity among 375CT chambers and brass thicknesses, you'll likely not get any real useful info. Certainly not more than I can give the guy anyway. Cheytac's aren't 308's.

 

Orkan, what's your recipe for the 352gr ? I have some CE mtac 352gr. Retumbo or H50BMG are ok I suppose ? What kind of speed do you reach with it ?

 

131gr Retumbo. Do NOT start there. Start at about 120. I'm getting 3160fps.

 

I ordered for me a Cheytac, Cal. .375 !
I,d it appriciate to get any reloadibg informations. Getting in Germany/Europe powder, bullets and primer.

Going to take my rifle later here down to Namibia. Open a shooting range on the farm up to 4.000 meters !

Thanx,
Thomas
