Re: Throat errosion concerning the large case 6.5\'s
Steve,
I'm so glad you responded to this post. I swear, I learn more from you in one or two posts than I learn all year on some things!
I appreciate your time sharing all this with me. Glad you didn't leave one sentance out either.
I'll let dad know about the 155's, that's interesting stuff.
I agree with you on the PPC case design word for word. There are definately diminishing returns the longer the case is, that's about the only difference I can see. When my dad was busting out 180gr bullets in his 300wsm at over 3275 fps and my 300 Ultra was only 20-30 fps faster, I was simply amazed! His bbl was only 1.5 inches longer too. Dad really thinks he's hot **** now, with all those super accurate WSM's he's building!
I'm workin hard on building something to knock that big chip off his shoulder.
I used to whoop his *** at the range routinely, now he almost routinely just cleans my clock! He's gotta be stopped!
That throat errosion formula stuff is pretty deep "theory", I think. Like you, the best thing about the longer necks, I thought, was to offer better protection by funneling the abrasive burning powder better down the center of the bore. Less direct "abrasive" blasting of the throat as it comes off the shoulder by bouncing back off the neck again. That's just theory too though.
Some guys shooting 300WM's in Highpower Comp (shooting Fast) say they don't get much over 1000 rounds before they rebarrel, but the round works!
Thanks for the capacities on those two, I'm saving all this good info ya know.
Thanks for using fireformed pieces too! You da man.
I appreciate ALL the insight here!
Now, tell me when you run accross someone shooting a 6.5/338 Lapua, I'm diein to know how their doing with one. Thanks again Steve.
