3030 bore size???/

[retiredPO]

Im trying to learn how to swag my marlin lever action,... is this the place, or should I be looking somewhere else,
it seems like you guys are talking waaaayyyy over my head.....

30-30 bore size should be 308 and yep this is the place to learn about making jacketed bullets. I make some very nice 30-30 bullets for my Winchester 94

The basic bore diameters of Microgroove Marlins run large, .303-.304", because the rifling is shallow, whereaz the groove diameters are fairly normal at .3085-.3090".

You want a bullet with a long bearing length, not shorter than the length of the.30-30 neck, and if possible with bore-riding nose not smaller than .302", with. 303" being better. With a 170-grain gaschecksd bullet a charge of 26-28 grs. of W748, H335, or 4895 works well.

Or IMR 3031 WOW! are they acurate

[uscra112]

Did I understand that the OP wants to swage? As in jacketed bullets?

For cast my Marlin likes 311041 and the legendary 165 grain Ranch Dog, now copied by NOE. Varget replaced 3031 for me, until I ran out. :cry:

Sorry,... i may not be saying it right,... I understand that there is a way to drive a soft lead piece thru the bore and then mic
the resulting piece of lead,.... but I dont want to try this unless im sure Im not going to hurt anything,....
do I just get a piece of soft lead, oversized, and hammer it thru???????

[retiredPO]

These are beautiful,... how the hell does a person do this.....
thanks

as far as slugging your barrel to determine what your groove diameter is get some split shot fishing weights get one slightly larger than your rifles bore. a wooden dowel smaller than your rifles bore Lube the weight up with RCBS case lube or something similar and drive it through. With an outside mike (provided you have an even number of lands) measure across opposing high ridges. If your rifle has an odd number of lands your going to have to use an indicator to get a measurement because a micrometer will not measure across the odd lands accurately. Generally speaking for "most" rifles that have been made in recent years you want to be shooting a .309 - .311 diameter lead bullet. and a .308 diameter jacketed bullet. YMMV

Please do NOT use a wooden dowel as the wood could break and splinter and stick in the barrel. Either get an aluminum or brass rod slightly undersized that will slide through the barrel. Egg sinkers are better than split shot. There are probably "stickies"describing this process and you would be ahead of the game if you reviewed them. PM if you are having trouble, sometimes I have to dig a little to find what I am looking for. DO NOT USE A WOOD DOWEL. Dusty

He's right about the wood. If it gets stuck, boy is it it a PAIN.

Now if you can't find an aluminum or brass rod, steels works fine.

Before you get your panties in a bunch about upswing steel down your barrel, it won't hurt it. I cast, swage, and build match quality barrels in my spare time. When we need to slug a barrel, to determine if the rifling is to the correct diameter, we use a Pratt and Whitney riffling machine, we place a STEEL rod, with the ends chamfered, in one end of the barrel and drop in some lead in the opened end of the barrel. You then take a second STEEL rod and beet the lead in between the two pieces if steel. When done, you simply push your slug out with the first piece of steel. A LOT easier than trying to shove an oversized piece of lead down the barrel.

This is how barrel manufactures do it. You not going to hurt the bore.

there is a sticky on removing the stuck WOODEN Dowell...
