You might very well be right... time will tell

Re: What do ya'll think about a 6.5-375 Ruger?

The 6.5-.375 sounds like a screamer. I'm looking into a 6.5-06 M40. I was speaking to my gunsmith who works pretty close with Sierra and he was saying that the 140grn 6.5 SMK has a "sweet spot" for accuracy at 3000 fps so the 6.5-06 gives just enough powder to hit that velocity and is ~90% packed.

The gunsmith also has a 6.5WSM that he did years ago before he verifed the stability issue with Sierra - it's accurate as all getout but he has to keep the velocities at 3000 fps so it's overkill.

Post pics when it's done!!

The 168 and 180 Grain Bergers would be tough to beat at with a 100 grain powder case behind it.

That would be my wildcat.
I would consider another bullet, and just throw in in a RUM or 338LM case. I am having 180 bergers shedding jackets on my last couple of trips out.

I am thinking your be in the WC870 or VV570 range of powders, but suspect that the large kernal size of the 570 is not going to be good for that case.


What barrel length you thinking about using? Another thought, just because of the necking down issue, why not just a 6.5RUM, other than cool factor?

Re: What do ya'll think about a 6.5-375 Ruger?

RL17 in a 6.5 Ruger isn't happening. I have been extensively testing my 6.5-300 win mag and H-US869 is slightly fast with a 140 VLD. 2000 rounds is also a very optimistic estimate. What makes you think almost doubling powder charge over a 6.5-284 will add 800+ rounds to life? I'll believe nitrating when BR matches start being won with 6BRs with round counts over 3000 through a nitrated barrel.
I mean it sounds cool, but I'm a lil hesitant that it is increasing barrel life 2-4 times and you don't have the whole shooting world flipping out to buy nitrated barrels.

I would try the coating on a barrel, but I am not letting them cook any of my actions. The manufacturer heat treated them where they need to be. Until someone can prove to me that hardening an action is not bad, I will let others guinea pig it.

I have been considering the -06, 284 Norma and WSM versions and was shying away from the WSM because it might cook the barrel to quick. The 284 Norma is about a 1000 rounder for good accuracy and I really don't want to get anything that will cook a barrel in less than 1000 rounds.

The 140 Sierra, Berger and other offerings might be my secondary plinking load, but my primary business bullet will be a 110 - 120 custom designed GS bullet. It will probably be the same length or longer than the 140 Sierra.

I've got this thing about 3400 fps plus because I like to zero at 300 yds
