Hey guys -- just got a google notification about this thread, and thought I'd pop in and say "Hi". I'm a one-man show over at Murphy Precision, so it gets a little crazy at times. To answer some of the previous questions:
1) Titanium is 40% lighter than steel / stainless steel, while being just as hard and strong. It is however still 60% heavier than aluminum. (But 3x stronger). Steel is 180% heavier than aluminum. (All for the same size / volume of material)
2) I don't charge extra for doing custom bases if it's something I *might* sell again to someone else. If it's something really off the wall, or very esoteric, then there may be an additional fee for the extra programming/setup work. Taller, or longer bases than normal will also cost more for the extra material, and longer machine time.
3) Lead times are generally a day or two for in-stock items (Most T3x bases, Remington 700, Savage, Christensen Arms, a few others in stainless and popular slopes.) Everything else is machined to order, and runs between 3 and 7 days on average. (I've been at about 4-5 days the last month or two.)
4) I try to answer the phone whenever I'm not in the middle of sandblasting, or doing Cerakote. If it goes to voicemail, it may be a few days before I get a chance to check them and return calls.
5) I *try* to answer emails every evening, but there are times when it may be 3-4 days if I'm really slammed. (My wife likes it if I come home occasionally

If I haven't gotten back to you by then, I might have overlooked your email in all the spam I get, and I don't mind if you shoot me a reminder.
Please let me know if you have any other questions, or if there are any bases you're looking for that I don't offer.
