311440 in 30-30 First loads with cast?

[DeadWood]

Loaded a few of these today for 30-30 in my Win94 trapper.

Lyman manual reads 2.480" for OAL.
Various brass trimmed to 2.028"

Does this boolit have a crimp groove? If so i found the OAL to be much shorter, how much i would say at least .050" if not more.

When i found i chambered a round at 2.475"OAL it chambered with resistance. I thought this strange so i ejected it. Looking over the extracted round i noticed the rifeling marks on the boolit. At first i attributed this to being because there .0015-.002" bigger than bore, then it got me thinking should the boolit be engaged in the rifeling? so i loaded some at 2.445" and same thing.

Just trying to be safe and aware of what i'm doing.

thanks for helping with i hope to be a beginners question

If you have light engraving, that may well be good. Heavy hard resistance is not good, requiring the bullet be seated deeper. What does the nose of the bullet mike. Have you slugged your bore ?

I load the 311440 group buy clone at 2.410.

nose = 1.304"
body =1.310"
barrel slugged 1.309

I would say light resistance not heavy

[Ben]

Ummm ? I'm not making my question clear.
Let's try again. Your numbers of 1.3XX I don't understand

Miking the bore of your rifle refers to the diameter of a lead slug driven through the bore ......When you say the barrel slugged 1.309. The bore may be .309 ", but not 1.309"

[DeadWood]

Ben i'm sorry don't know why or where the 1 came from :?:[smilie=b:

yes bore slugged to .309
nose mic. to .304

[Ben]

That .304 nose is about .002 " too large for my taste. Most standard .30 cal. rifles will cause problems in chambering the loaded round with a nose that large. Not certain what to tell you? There is no danger in shooting a bullet with a large nose dia. if you can get it to chamber ( by seating the bullet deeper in the case neck ) .

If I can, I always like a nose that is .301 - 3015 in dia. for ease of chambering and optimum accuracy in the majority of my .30 cal. rifles that I own.

With that said, I have a " fat .30 " bullet. A Lee 155 gr. Spire pt. with a nose of .304 ", it requires deep seating in several of my .30 cal. chambers, but it is a REAL SHOOTER !

Good Luck,

Ben

does this boolit have a crimp groove?

[imashooter2]

No it doesn't. The front groove gets no lube and is seated out of the case.

[DeadWood]

thats what was confusing me. thank you

[mroliver77]

Load it to the length it will chamber. Dang, I better go measure some noses.

Currently, there are four versions of the 311440 out there. The original Lyman, the GB version, the BRP version and the NOE version. All are cut a little differently. The BRP has a crimp groove and is the biggest of them (meant for the worn Winchester 94 throats), but works in several calibers as well as worn 30 caliber rifles.

[DeadWood]

Jay, do you know what mold these were from? Going to try and post some pics, tomorrow, but don't think this is a big issue. I'm not familiar with loading CB's and am tripple checking everything i do (my wife hates me for this). My rifle is a newer Win. 94AE.

It was my understanding that when using CB's in this caliber there would be light contact of the boolit with the rifleing? thats why a crimp is needed so if one ejects a loaded cartridge the boolit would not come out.

iamashooter2 loads his pretty deep. would there be any draw back to this? Lots of jump in the throat when fired.....

Would like to see what others are loading O.A.L. ????

If anything else i'm learning right [smilie=s:

You didn't mention how you were sizing. One of the drawbacks to the 311440 is the bore riding nose. Normally, it's a friction fit which is good for accuracy. If you're base first sizing, the resistance of seating the GC and crimping it may be just enough to "bump" the nose to a diameter that's oversize and you'll have chambering difficulties.

I use a nose first sizer at .310" to size and seat the GCs and then come back and lube in a seperate operation in a .310" die. This protects the nose dimensions and they chamber nicely./beagle

[DeadWood]

miced the nose again = .302. Good to go there. I think one of the first 5 i may have had a long case which got my attention. Also this being my first lever gun and not familiar with the action and having only put less than 50 rounds of jacketed bullets down it, didn't help.

I loaded some today at O.A.L. of
2.447
2.455
2.470
2.480
and chambered each. All chambered fine with light engraving. The 2.480" was a little harder to chamber not that i couldn't, i just didn't like the feeling. Left a little more "marking" on the boolit and in to the first groove.

I may have a little to much crimp going on will back off and try again next time at the bench.

All crimped in the first lube groove (2nd down from top). Is this acceptable? or should it be seated down in case?

[Newtire]

I crimped mine in the top groove so just had the first band and nose sticking out of the case. Mine wouldn't even begin to chamber if I seated out further. I was shooting these in a 336 MG and a '93. Nose mic'ed at .300. This was one of the best boolits for the 336 that I have. Sized to .310" works great. Sized to .311", won't even chamber. Kind of a finicky rifle. The '93 and the '94 angle eject a little more forgiving.

[Bret4207]

Cast at normal pressures is very forgiving. I'd go with the one that pleases me the most, based on personal preference, and try 50 rounds. See how they shoot and the cases look. If all is well you can stay there or tinker with it.

[Throckmorton]

Be sure to get all the jacket material out of your bore before shooting the cb's.the two don't mix very well in some guns.

And don't forget ,along the way, to try some pistol powder laods for economy and fun.
especially fun.

I had not seen that this thread continued. Kevin got the boolits from me. They are out of the first GB Lee 6cav. I sized to .310. Noses are .302 on mine. I did size base first but seen no problem with upsetting the noze. It scared me when he posted .304! On my MG Marlin I load them so that I can see where the rifling just "kissed" the .310 or largest portion of the boolit. The nose shows very light touches of rifling. They eject unfired just fine. I record the oal in my book but it wont help anybody else as they should be loaded for each separate gun.
