The July issue of guns magazine contains a very good article , by john barnesness ,( darn good writer that one !) called Quarter Bore heaven.
If any of you guy's are quarter bore nuts like I am , or if you just happen to have a single .257 caliber rifle you load for you should check it out.
He loads for the 25/35 , 250/3000 .257 roberts 25,06 and the .257 weatherby magnum.
I have exchanged PMs with John , on the Roberts and the wetherby mag, on a few ocaisions.
The data that intrests me in particular, is in The Roberts. (duh , I do call myself TJ Roberts). He shows a load using 50 grains of Ramshot magnum , pushing a 120 grain Partition at 2890 FPS , with a group of .66 from a 24 inch barrel.
One thing I like is that john is using his own rifles on most if not all the testing.
Another load I realy like using ramshot hunter , with a charge of47 grains putting a 100 grain barnes tripple shock into.67 and a muzzle velocity of 3153 24 inch tube.
FYI, I get about the same results with H-414 and I use 46 grains.
My velocity is just a shade less, but I shoot a 20 inch barreld ruger RL.
I will post pictures of my Roberts rifles if I can, just to add a little color to my post.
If any body thinks the Roberts is to light for a big mule deer , have a look at that load with a 120 grain Partition at just under 2900 FPS.
That will drop even the biggest mule deer , and probably be just fine on a caribu too.
