10" 30-30 Tender issues....

[waco]

What is the deal with the throats on Contender barrels? My 30-30 barrel, 10", with brass prepped and trimmed to length and loaded with a Lyman 311041 jammed into the rifling measures 2.333"??? WAY short.

This puts the gas check way below the case neck. Is this a common problem with tender barrels?

Anyway, this thing is a beast with full power loads. So, I bought a Lee 311-100-2R mold for light plinkers. This one I'm hoping will load and seat into the chamber better.

Has anyone else run into this before?

Thanks again guys. Waco

I got the idea of shooting the Lee 311-100 2R RN also
about 6-8 months ago out of my 10" T/C, 30-30 Win.

I had dismal poor results.

Hope your results are better.

[waco]

That's not incouraging...

[waco]

So what has worked for you Ben?

I think I'll give that Lee mold a try. At least they will chamber....:/

I hope that they do well for you ?
Let us know how they shoot.

Just loaded them last night. Not sure when I'll be able to go shoot them...

Waco, sounds like it need the throat cleaned up. Spend a little time on Bellm's site, much to see concerning T/C factory throats. There are stellar and there are horrible,,,,,,

30-30 in the Contender pistol can be *very* accurate. :bigsmyl2:

Load some and try them seated with the GC below the neck . In my 7-08 striker I have to seat the GC's below the neck with either boolit I shoot and have had no issues . Also is your barrel a bull or Oct.

[ubetcha]

I have a super 14 in 30-30 win and use the RCBS 165 gr sil. They are cast from WQ-WW and sized to .310 and have a nose of .302. My OAL is 2.595.. The gas check is still inside the neck but just at the end. I hope my attachments come through ok.

What kind of groups are you shooting with that bullet ?

Bull barrel

[marshall623]

The short throat is odd. T/C is famous for the super long throats. What powder are you using .

[waco]

I loaded those 100gr. Boolits in the picture with 15gr. Of SR4759

[leadman]

Some of the older Lyman molds for the 311041 have a larger diameter, around .311" to .312". These seem to hit the rifling sooner than the newer molds that drop at about .310". I have no problems with the 311041 in my 21" tapered carbine barrel or my Super 14" rechambered to 30-30 AI.
I size to .309".
I have probably slugged 30 to 40 T/C barrels and they were all on spec. so I size only .001" oversize.

That seems like a good start

[ubetcha]

I use this bbl to shoot IHMSA silhouette . It's been awhile since I've shot a group on paper. As long as it hit and knocked down the steel targets, I was happy.If I recall, I was satisfied with 1" at 100. I don't know if "I" can hold a tighter group. But my matches this year with it were not good, so I need to re check my scope settings and come up with a new powder load because I have used 18gr of S4759 with great success, so I will be paper testing . I also need to get out and shoot more as the only time I get to shoot is at a match. Was thinking about R7 if I can find it locally. My new toy is a 12" T/C 357 mag bbl re chambered to 357max.
Waco, Yes this is a bull barrel

[35remington]

That's a lot of 4759 with a plainbase Lee bullet. If it doesn't shoot well, consider loading considerably less powder.

X2 I assumed that was a GC bullet my bad.

.30-30 chambers traditionally have very little throat. SAAMI spec. has it at 0.015" and at a 15 degree taper. All of my .30-30 boolit molds start tapering at the crimp groove and/or have bore riding nose profiles. The Lee 100 grain RN does not really have a crimp grove and while designed for .32 revolvers I believe they will work if you seat them deeper.

+1 on 30-30 chambers with little to no throat, I plan on buying a .30 cal throating reamer from a maker in Mich after the holidays and cleaning up a 30-30 that has given me fits....can't chamber a 150gr bullet let alone a **** ton of ~145gr tracers I have set aside as "plinkers"....I had a contender barrel in 30-30 but sold it in favor of a .22 match...lot less of a headache on that one.

[45-70 Chevroner]

I have a Super 14 in 30-30, and have used a number of boolits in it (100gr RN, 115gr RN, 130gr SP, 160gr RN, the first four here are Lyman. 180gr RFN Sil. RCBS) the only one that will not shoot well is the 180. The 180 chambers ok but it is too long for the twist rate in the contender which is 1 in 14. I bought two new Lee two cavity 150gr RFN molds. I have about a 100 of those loaded with 10 gr of unique, but have not had time to shoot any of them.

[WALLNUTT]

1 in 14 must be an old barrel. Newer TC 30cal barrels are 1 in 10 and will stabilize about any 30cal bullet.
