Barrel for 30BR

[Bill Norris]

Redding makes 30BR dies - Are these good to go?

Oh yea, Redding & Wilson really work fantastic with both my rifles. Both are chambered with same reamer.

Awesome. This should be a fun little weekend gun.

I liked my 700 bench rifle so much I had Zack build me a hunter from my Model 7 Love shooting both of them for sure.

Take a look at Harrells sizing die as well.

700 on the left Model 7 on the right.

Is a 30BR reamer something the big guys are going to have a print for? I understand zero freebore is the norm?

Oh yea all should have it. Mine is from the Robinett reamer with zero free bore.

The neck diameter is .330 and brass should be turned down to .098 to give good clearance.

I would probably go with a JGS reamer as they have Randy Robinett's newest design.

 

[LVLAaron]

Thanks! Seems like a fun cult following for this little guy.

Is there a particular brand of brass that is preferred? Lapua I assume?

 

[JimPag]

Nope....PPC

Absolutely Jeff. Try shooting a 30BR at the Group Nationals. As they say up here in Maine, you'd get used some HAAAAARRD.

Here ya go folks - for a 30BR reamer, it won't get any better than this.

Simply call, or, e-mail JGS, and order 30BR ROBINETT V2 (for Robinett version 2). Though this may prove neither better, nor worse, than reamers featuring other dimensions, it will certainly prove excellent! If wanting a new 30BR reamer, this is exactly what I'd order.:D No more messing about...

The Redding dies are good - so long as the chamber reamer cuts a big enough web-diameter @ .200" DATUM.

L.E. Wilson is now making excellent threaded FL/NK bushing dies, dies, and there is the reliable
Harrell's Precision option.

Harrell's make a variety of body diameters, which correspond to correct shoulder bump (head-space) - AND, if you don't achieve the desired case:chamber "fit", I believe that they will still exchange for a better fit - the fit usually related to the 'dreaded click' (difficult primary extraction) caused by too tight/close a fit between the virgin brass, chamber, and die-cavity diameters.

That said, my original die was a Redding [7mmBR] Type 'S' FL/NK bushing die, on which, using a carbide chucking reamer, I opened the neck:bushing port so that the .30 Cal. necks would pass through without being sized/touched. I got lucky: with my original reamer (.200" DATUM Spec. Dia. 0.4707") and brass, that die has been a perfect fit. Out of curiousity, I recently purchased a L.E. Wilson, and am very pleased with it.

In hind sight, going with a minimum [of at least] 0.472" Dia., @.200" ahead of the bolt-face is a more desirable option. RG

Is it correct that you incorporated this change into your new reamer specs?

I own 3 different 30BR reamers. One is a true Robinette reamer and the other 2 are totally different and all the barrels chambered with all the 3 different reamers all shoot very well. No difference. It's the person behind the trigger who knows how to tune a rifle, read wind flags and pull the trigger at the right time that counts not the reamer specs.

 

[WSnyder]

No difference.

No doubt but the Robinett has a ton of history and info on the web which sort of makes it the easy button for those that might want a 30BR.

Yes.
Here is a print of the JGS 30RobinettV2 - salient features:
1) 1.510" max OAL (-0/+0.005"); same as original
2) web diameter (0.200" ahead of bolt-face): 0.472" (-0/+0.0005")
3) 0.331" neck Dia. (-0/+0.0005")
4) 1-45-0 throat angle (1.75 deg) (+/- 15 Min.); same as original

I don't understand why having a name attached is improtant - reluctantly, I granted permission for JGS [to use my name], because they assured me that ANY dimensional alteration will remove my name.

As I have experssed many times: altering dimensions may make for a better, or, worse reamer - however it ain't the SAME, therefore, it is [and should be called] something else!
Good shootin'! RG

Finally got a hold of some H-4198 and loaded a few of Bart's 112 for my 30BR built by ODCR (WSMNUT). Although the V V powders do very good I think I may have shot my tightest group so far with it.

very nice group

My experience with an 18 T barrel here in cold weather is that it’s marginally stabilizing bullets even those on .925 jackets. I have settled on 17 T. In a warm climate it may work fine.
