What all do I need to get to cast somebullets for my 270?I would like to try some 130 lead bullets as an experiment first to see if I really like messing with it:confused:

.270 does not have very many choices, Lee does not make one, so the rest , Lyman, RCBS and Saeco ae $53 and up, only 130gr is a RCBS special at $90, plus handles, Lee 6 hole handles will fit the other molds just fine, in some cases will need to be thinned down a little, no big deal.

Lee does not make a sizer for .278-279, but a .243 sizer die could be opened out, or if you have a lathe, do as I do and make one from scratch.

Gas checks, a 1000 is about $20 and some lube, a pot to melt the alloy and something for a ladle.

I do not know of anyone casting for the .270, but a few cast for .22, .243 ,.25, 6.5 and 7mm, so there should be some help out there.

I cast for .243 and have had good results.

Lotsa luck, Don

Hey Don.Thanks for the prices.I think maybe I should just buy stuuff to cast for a 45-70 and wait on the 270?Is casting for th45-70 cheaper than fopr the 270 because of the mold price?:confused:

Oh yes;

Lee has several molds, very economical, Lyman and RCBS have some that cost about 3 times as much, plus handles, see Lee handles, for the rest of the molds.

It is not just the mold prices,Lee has a .457 sizer, about $12 and a universal case expanding die, essential for cast bullet loading, for about $8.

The .457 die is easily polished out to a size to fit your groove diameter.

I do have the Lee factory crimp die, works fine, in fact I have mostly Lee tools, a few die sets, not Lee , but only 6-8 of them, as to 15-20 Lee sets and about 25 Lee molds, plus One RCBS , 2 Lyman and one DGW .

Any more questions, please ask.

Don

Would like to know if its a worthwhile option.

Hey Grey.Aftyer Don told me the mold price I have put the 270 cast bullet on the back burner.I am not a bullet caster but am interested in it.I`ll start with a cheaper caliber to see if I even like it first.Its a shame they are so high though.I would love some solid cast bullets to shoot in my 270...:sad:

TG, try some Beartooth bullets, they have .270 bullets. I've never bought cast bullets (except for handguns), but these are pretty good by all acounts I have heard. Go here:

Thanks Charley.I will buy some.I am really interested to see how they will shoot with AA3100 in my Model 78 Remington...:thumbs:The 270 is my favorite deer rifle and I would love to say I did everything on the cartridge but until I learn how to cast bullets, this would work well....:thumbs:

LTD and Moyer's also have .277 cast bullets,$ 9.30 a 100 , $45.50 a 500 at moyer's, $50 a 500 at LTD.

You will need to slug your bore to find out the groove diameter, usually shoots best if the bullet is .001-.002 " over the GROOVE diameter.

TG,
 
Check out the post I did on  "Gas Checks on the .45-70"  thread regarding cast bullets in rifles.
Depending on how fast you want a cast bullet in the .270 to go, using heavier bullets, say in the 150gr. weigh range, will allow you to approach jacketed bullet velocities much closer than the lighter ones.
In other words, you'll be able to generate velocities much closer to a jacketed 150gr. jacketed bullet using a 150gr. hardcast, than you will comparing a 130gr. jacketed, and a 130 gr. cast.
Not "as fast", but closer to it.
With cast bullets, your limited by the amount of pressure that your alloy will tolerate. Not necessarily by the speed or bullet weight, if you follow me. Heavier bullets allow you to generate more velocity or energy, while still staying in the "comfort zone" of your particular alloy pressure wise. 
As mentioned on the other thread, if you use the equasion 1422 X 22 = 31284psi and you pick a load that generates 28000psi (or approx 5% below your alloy's workable limits) it will perform very well from the alloy's perspective.
1422 is useable as a constant. Linotype will net you BHN numbers of 21-22.
Oven heat treating WW's with 2% tin added will net you 31-35BHN.
To oven heat treat them, place one or two bullets on a cookie sheet and starting at 400degrees, keep bumping up the temp 10 degrees at a time until you see the bullet(s) start to slump. Back the temp. off 10-15degrees, load up a sheet full and place them in the oven for approx. 20mins.
Have a bucket of ice cold water ready and when you pull them out, dump them directly into the water. Temperature on both the oven, and the water, and the time the bullets are left in the heat make a difference. Varying these only a little, will make a difference in their finished hardness.
 
Sounds like a lot of bother for a cast bullet, but really, it's not all that hard....a little time consuming maybe. The finished product is well worth it, and one sitting will net you plenty of useable bullets.
Sizing and lube are paramount. Gaschecks are preferred. Once you've gotten through the preliminary steps, such as slugging your bore, finding the appropriate alloy and load, all the rest is just pretty simple.
 
I've gotten loads in my 22 CF's that'll shoot right up there with most jacketed loads as far as accuracy is concerned.
 
Take care,
Bob
