Ladder Test Results - 30 Nosler - 215 Hybrids

[fnlights]

I'm at 3.578" to lands so no. The mag well is 3.850

Perfect. I am going to email Jimmy now and get his thoughts on SAAMI or around .200. Ideally I would want to be around that .200 to get the best results from those 215's and wanted to make sure that would not change the bottom metal

Which is strange because the OP got one of their off the shelf rifles and he does not think it is SAAMI. Unless that was someone's custom and they ended up backing out or something.


Will having them put in the extra freebore require a wyatts box or something different than their APR BDL?

Measuring to the lands can be tricky. If you have three people measure the same rifle you will probably have three different measurements. In fact if you use three different methods you will probably have three different measurements. I know I do.

Yeah but he's at 0.058" shorter. Nobody can be that far off in difference

Mine jumped 50' when it sped up. Got a 300 RUM that speed up last week. Went from 3.140 on 215's to just over 3,200'. Since it sped up gonna run the 245's through it now.

Mine did right at 50 as well. I'd love to run the 245s but at a 1:10 I'm maxed out with the 230s.

I think we lose sight of how precise the measurements we are dealing with sometimes..058" is less than 1/16" of an inch. I can see being off that far depending on the method you are using to measure.

Yes it is. But I'd argue that. In the rifle making world that's huge.

Waiting on a call from Todd. So the in house gunsmith said mine should have been cut to the saami spec of 0.110" but there's no way it could have been. It's got to be closer to 0.200" like Sherm said.

You'll have to let us know what Todd says because I am also thinking it is closer to .200.

It will be interesting to hear. I am not sure how you could unintentionally cut the throat deeper with out cutting the head space deeper with a SAAMI reamer. I always thought you had to use a throat reamer after cutting the chamber to increase free bore but then again I have never chambered a rifle....

 

[Longtine88]

I'm thinking Todd ain't calling

HA it is looking that way! Who even is Todd? I figured the head gunsmith over there should know? But he told you it was SAAMI, which is hard to believe lol.

 

[sierracharlie338]

Yeah same on mine I have tons of space in the mag for length compared to where I'm at now.

That's it I'm going back to measure my chamber LOL y'all are making me question my sanity

So I reached out to Jimmy about the Berger 215 and this was his response: "Our normal reamer is a "SAAMI" reamer with .110 FB that has done well with 210 ABLR's. We do have a reamer for 230 Bergers but I don't have a print with me right now. Unfortunately just like the other 30 cal mags, the 215's seem to be right in the middle."

So it looks like it's either the SAAMI or the 230 reamer. I wonder what that 230 reamer measures

 

[Longtine88]

Well the bearing surface difference between the two (215 vs 230) is 0.066"

So that 230 reamer probably would be prefect for the 215
