I either can't find it or never asked for the data for this combo "at .270 pressures"?
I have data posted (and thanks for that) at 51K, but I need to get an idea for it at 63-64K?
Winchester 70 FWT 22" barrel
Norma brass
Nosler 120 BT/ 120 TTSX

The Remington 700 Classic 7x57 got sold...it came with a Wisner ( or similar) Mod 70 type safety/bolt shroud. I had a Timney trigger installed and the two never got along! I spent a lot of money, on two smiths, who fitted/refitted, polished/polished some more and it still wasn't right. It didn't matter if it was the factory trigger either. At cocking (dry firing, snapping in even) "sometimes" it would need a very hard bolt lift. Sometimes not! The Mid position sometimes worked...sometimes not. Hog wash and poppycock! It all got sold last week to a fellow who didn't care! I am "severe" when it comes to dealing with aggravating rifles! ha I "did" find a Mod 70 FWT (push feed) in 7x57 so I'm happy...for now...hopefully. :)
 
Friend loads 50grs IMR 4350 with the 120 bt in a Ruger mod. 77 grouping under an inch at 100yds. He was ready to send it down the road but is well pleased how it performs on whitetails. Gave my son a Mod 70 like yours in 7x57 planning on working up a load with the 120 bt this winter for it. It groups the 140 bt with H4350 and H414 at about 5/8-3/4 in at 100yds. Dan.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63250 psi, or 436 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63250 psi, or 436 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Thanks again Doc! Don't you have a 7x57 FWT or is it the .280? Big Game looks like a good one to try, just wanted to know too about cold weather use.
 
I have several .284 calibre rifles (7X57, .280 Rem, .284 Win, etc). All of them are FWTs. Gotta' say, I love 'em all.
