M17 Rifle
@Rule 303
Greg
Boyds stock, llijla 24 inch match barrel, timney trigger
Caliber is a combination of designs melded into 1 cartridge.
They are
The 30/40 krag Newton
The 25/303 Epps
25/303 Tipan or Harrison magnum
It took the best features of all
Minimal taper case
35 degree shoulder moved forward to give a .257 neck length instead of .311 long.
I called my creation the 25/303 Epps Newton improved.
Loaded with Hogdon superformance at sensible levels it gets the following
100 Barnes ttsx 3,600+ fps
115 nosler combined technology silver tip or 117grain SST 3,300+ fps.
These are actual chronoed velocities on a 36 degree Celsius day.
I hope this helps.
Went to the range to check it today
0.4 inch 100 yard group and a bit under 0.8 inch 200yards group. Pack up go home that will do me.
Cheers mate Bob
