That,and it gives the bullet a runnin' head start at the rifling(Technical Term). So you can load to higher pressures,without getting kilt(Technical Term). <br> <br>Proponents dig the speed(and I personally think the throat lasts longer). Opponents cite accuracy issues. <br> <br>I've had 'em throated most every which way. A Rem 700 based Custom Rifle,wearing a 257WBY SAAMI chamber/throat,is my favorite chambering on the Planet. <br> <br>She's fast AND accurate......................

I was out at the range over the weekend, slippin some moly coated 150gr Swift Sciroccos thru my 7mm Rem (I'll be writing up a report later). Had a fellow shooting a .257 WSM next to me. It was based on a Ruger #1, rebarreled by Montana Rifleman, with a SS bbl at 26". <br> <br>He was shooting 115gr Nosler BT's (non-coated) and loading with 60.0-grs of RL-25. We were both curious about the velocity, so we chronoed them at 3247 fps. He said that he had loaded up to 62 grains, but that the primer pockets opened so much that the cases (necked down brand new .300 WSM's) wouldn't hold a primer after one firing (at 62grs)!! <br> <br>Just a data point ... RL-25 may be too slow for best results in this cartridge. <br> <br>...... S.B. <br> <br>

Hum, I'm getting slightly over 3300 out of my 257 AI with 100 grain Nosler Ballistic Tips. I guess I should be happy.
