I have my bbl. throated for the 150 SMK for optimal bullet placement in the neck. The bearing surface is so much longer with the ELD-M that it would clearly be into the powder collumn. after the throat has eroded somewhat, I'll give them a whirl.
Understand!
Old thread I know but speed isn't everything but accuracy is. The 5Rs bring that to the table even if you can't run bullets as fast. Technology is moving faster than the barrel companies are. Relax, they'll catch up. Accuracy is there better than ever before.
I don't believe the 5Rs cause bullet failure. I don't believe they are as fast as some others are. Certainly just as accurate. Yes, IMO, I think bullet technology is actually faster than barrel technology. At least in the last few years.
One of the things we need to remember and keep in mind is that from the early days of Benchrest competition, thinner bullet jackets were used for competition. With the evolution of long range competition, heavy for caliber (read that LONG) bullets and very fast twist barrels to stabilize those bullets, heavier jacket had to come into being. How many times have you heard "I would like to use the Berger HUNTING bullets for competition"? The reason is, I believe, is that they are a tad bit more accurate than their heavier jacketed competition counterparts. The problem is, now that we have fast twist barrels, is just how THICK of jackets do we need in order to keep bullet failure from happening? I believe this is still being investigated! You may even see such "warning / disclaimers" in the near future of " minimum 7 twist barrel with 5R rifling".. Both barrels and bullets are developing at break-neck speed, which will demand a higher level of selection, both to the projectile used and the necessary barrel, to minimize or eliminate bullet failure. NOBODY wants to be at "The Nationals" and have bullet failure!
Every 5r I’ve ever had has been noteably faster than any equivalent 4 or 6 groove. Not to dispute you Frank, you have a lot larger sample than I’ll ever have, but that’s my experience
Your correct, I'm sorry. I didn't mean to generalize that Bartlein barrels are slower than some other companies barrels. It's my experience from the Bartlein vs Broughton barrels I have had, the Broughton's were all faster. In the beginning, mid-range and end of the barrels lives. Same loads, same barrel lengths. Shouldn't have said "Others". One other barrel makers barrels were faster than my Bartlein's. Maybe your test results showed Bartlein to be faster than all others. My results didn't match those that yours did. I had a choice of buying a Bartlein or Broughton when building a 338 Lapua Imp rifle. I chose the Broughton simply from my results knowing I was striving for the most velocity I could get from the barrel length I have. I knew my Broughton barrels were the fastest of all my barrels so that choice made sense. Wasn't stricktly accuracy because if it was, Bartlein may have been my choice.
I only know it's a 5C barrel. All of them are that I own and they shoot well. Can't say better than my Bartlein's but well. Bartlein barrels will always wear and action in my safes and be in various hunting rifles I own. My 284 shoots better than any rifle I own with a Bartlein HV barrel. For some reason that I can't explain, my Broughton's just are a bit faster
