.308 win F/TR chamber

[cmillard]

The above was the loaded round. Now, figure it will have to seat bullets ever so slightly more, i think I will be fine on boiler room.

You have more than 0.169” freebore if that is the same length of your chamber. Load long a bullet and extract the round. Are you sure your not seating the bullet when you are chambering. I bet its shorter if you pull that out of the chamber without firing. That would explane the difficulty closing the bolt.

looks great something is not right

 

[cmillard]

Yeah, i had an issue with my LnL guage.....it's all good now

 

[cmillard]

3.160 is where ogive is contacting lands. The shank is still above neck/shoulder junction

Ive been wanting to try my 208 Bergers with my 308. It doesnt have a long throat. I have liked the velocity i get with powerpro 2000mr with 180 gr bullets. It should work well with heavies i would think

 

[cmillard]

Yes it would, but then the problem will be that it is double based and tempermental.

First of all I’d suggest that you shoot something lighter than the 215, recoil management is unforgiving on an F class target. It can be done, I’ve done it, and I know of about 2 others who have had success with it, but if you’re new to FTR your going to lose more points to rifle handling than you’ll ever make up on windage, and take a beating for your efforts.

Second, the 215 needs about a 220 freebore to stay above the junction. If you’re there then you do not have a .168.

There may be some people shooting 208, but the absolute gold standard and FTR is the 200.20x.

If you want heavy, then there is really no point in shooting the 215 since Berger made the 208.

If your rifle really has a .168 freebore, and your not shooting 1000 yds, shoot the 185 Juggs.

It will, until it gets hot. Back in the Varget drought in about 2013 before we found N150 it was tried by a lot of people. That is the reason I discovered and started shooting N150 in about 2015.

I will say this, I am no stranger to recoil. I have shot extended range sessions with heavy recoiling 12 Guage shotgun slugs and those sessions would cover my shoulder area in bruising. I have shot extended range sessions with centerline rifles as well including large caliber magnums firing heavy bullets as well as high round count range sessions in sniper school. It has been some time since I shot competition, but I do plan on getting back into it. Also, as far as the throat goes, that was the spec that NSS gave me. I got my LnL Guage issue addressed and a quick change of the seating stem on my LE wilson sester die, the rounds easily chamber and bolt closes smoothly. As an added measure, I unscrewed the barrel, torqued it back down and re-checked headspace. Everything is good now......minor hiccup. I will pick up some N150 tomorrow and start real testing. I will say that this will be a minimum 300 yard zero rifle, maybe further. It has a 50 MOA base along with 20 MOA rings. When I eventually get some 230 smk, that is what I will hopefully settle on for projectile, but I will let the rifle tell me what it likes.

 

[mattt]

What is your chamber free bore ? this thread is great

 

[cmillard]

According to NSS .168

 

[mattt]

have you measured it yourself ?

 

[mattt]

is this thread a trolling attempt or a real one, so much wrong.

If you put 70 MOA with the rings and base, not sure you can zero even at 300 yards.

You are probably right.
As far as to the trolling part from the other fella, I'm not sure who you think is trolling, but if you are talking about me, that is not the case. It started with a simple mistake, honestly kind of embarrassed about it.....the rod that slides back and forth on my LnL Guage, the rod that pushes the bullet to the lands.....it was all because of that. So, maybe go through and re-read the thread before you think I am trolling

On trolling, I think what others may be thinking is your insistence on using a bullet that should not work with the stated freebore and the reference to sniper school - along with your comments on being able to handle recoil.
Several of the members in the conversation have a lot of experience with the bullets/chambers involved - they know from experience.
Someone referencing sniper school is always a 'flag'.
When competing, it's not about being able to 'handle' recoil. It's about keeping the shots in the X ring, or at least the 10 ring. For that, recoil is not your friend.

Your comment - sounded a little like bragging - on 70 MOA and zeroing at 300 yards seems to indicate you have little experience at this.

All that said, you can have confidence that everyone wants to provide their expertise and experience to help you in what you're trying to do. In my time as a member here, I am often amazed at how much many of the members here will try to help. Many of them are among or at the top of their discipline.

I understand where you are coming from, but maybe they should not judge based off of someone's background. Also, maybe instead of shying people away from trying something that has been supposedly tested before and didn't work....maybe throw support behind it. Our country and community of shooters doesn't grow or gain knowledge by just doing the same old thing. We do it by trying new things and innovating. Maybe someone can come up with a good combo that works. That won't work by just shooting tried and true 185 loads. I understand that mindset to just shoot vanilla flavored loads. Remember when it was just 168 grain loads and nothing else? As far as being able to handle recoil, if some of you knew my background (a few here actually do and know me personally) you would understand. Feel free to pm me and i can fill you in, it's just not needed here. Also, I like pushing limits a little bit.....I do it with handguns also. My reasoning for having 70 minutes of cant built into base/rings.....why set up a scope that has already used up half of its adjustment by having no cant in a base/rings, when you can set it up to where you have all of your adjustment at your disposal. I have ran out of adjustment in scopes before where if I had forward cant, I wouldn't have had to hold off. So, I know my zero distance was going to be out there.....I just don't know how far yet
