270 150-160Gn Boolit

[Four Fingers of Death]

I'd like to get a mould for practice and hunting for my 270 Winchester.

Any interest?

[hicard]

Good luck Four Fingers. I tried to get a 110-120 gr 270 started for my 6.8 Remington SPC AR-15 and didn't get too far. A 150-160 gr is a bit heavy for my needs.

[Four Fingers of Death]

Yep, I saw your thread, bit light for my needs, don't worry about food luck, I'm gonnal wish you good luck! lol`

I have the book, Jacketed Performance with Cast Bullets by Veral Smith. I should try at least one of his moulds I suppose.

[Firebricker]

I would have some interest in a mold for my .270 FB

[GabbyM]

How about a copy of Lyman #287641 shrunk down by .007” for our 270’s ?
Goal of exceeding the .327 B.C. of the RCBS 150 grain bullet. #287641 has a B.C. of .382. Add a hollow point pin for hunting.

I’ve that RCBS 150 grain shooting at 50 yards with a vertical string of under one caliber.
26.5 grains of H4198 over a standard Wolf LR primer. That’s from a noodle barrel Weatherby Vanguard with 4X Weaver K series scope FL sized brass from a different gun. De burred flash holes and uniformed primer pockets.

RCBS 27-150-SP works, although you are unlikely to get more than .278 on the bands out of the RCBS mold.

Lyman 287405 (150gr 7mm Loverin) can easily be sized down to .278-.280.

I like GabbyM's idea. I would want it to drop at .280-.281 on the bands.

[GabbyM]

I've a Lyman #287405. Lucky for me I have it for my 270 as it barely cast a .285 bullit.
Have a .280 size die from a pile of stuff I bught. My rilfe would not seam to need it but I may try some for kicks. Yes my RCBS does not get sized down but a few tenths. But that's a good thing whith hard bullets as it gets tough. Am running a .278" die. If the bore wears to where a .278" die is to small then the .270+" nose will also be to small to rid the lands. That's when I'd either rebarrel it or run one of the Loverines at .280" with no bore ride.

I have an older Ruger 77, not particularly worn, but with a long throat that prefers .280". I have a more recent vintage Ruger #1b with a shorter throat that handles .278" just fine.

I'm more interested in a bullet for the 77 as I have other plans the for the #1. A 150gr@.278 is already reasonably well covered by the RCBS 27-150-SP

[rogsir]

i'm in for a good 270win bullet, 150/160 grs hp with gc makes a good hitter.

[nanuk]

I like the idea with a good sized flat nose

[C1PNR]

Yes, a nice flat point on a 160 grain should give us a nice hunting boolit with at least a decent BC, if that means anything at the range we'll be shooting.

[Four Fingers of Death]

A 260gn 270 booilit should have a pretty impressive BC, lol.

Obviosly you meant 160, a flat nose is fine, but we need to have it feed in Bolt Actions, designed to feed pointy jacketed bullets.

[altheating]

I too would be interested in a well designed 270 boolit! What do we need to do to get this project rolling? I was thinking 140/150 gr. Also need it to function in a bolt action Ruger 77.

[ktw]

The best solution is to have several people send user 45 2.1 impact chamber slugs from their rifles. He will propose a design based on measuring those.

That process worked out well for the recent 6x45 bullet (BRP 246-77-GC). BRP even picked up the design for that one as part of his standard catalog, meaning no minimum number of molds for a group buy was necessary.

[GabbyM]

Consider having the gas check shank cut for 7mm gas checks.
Mountain Moulds offers that as an option on 270 moulds. 7mm is actually a smaller diameter shank than 270.

Checks are easier to come by and many people will also own a 7mm caliber.

[altheating]

Tell me what I have to do to make impact chamber slugs to send to him. Great idea on using 7mm GC's. That would save me from keeping two sizes in stock.

Yeah, I just corrected that. That 260 grain would look a lot like a pencil, eh?

As the song goes: "What was I thinking?"

[Four Fingers of Death]

I know what I was feeling, but what was I thinking?? B

[dromia]

I would be interested in a good heavy .270" boolit mould in four cavity.

[dromia]

Tell me what I have to do to make impact chamber slugs to send to him.

Texasmac has a tutorial (http://www.texas-mac.com/Determining_Case_Lengths_Chamber_Casts_and_Impact_ Impression.html
) on the most common ways to measure a chamber/throat. A description of impact slugs is near the bottom of the document.



You end up with something that looks like this:

TTTop. :-D

KTW, for some reason the link you posted is not working. Following is a link to my article on chamber casts & impact impressions, which currently works.

Arrrrr, no pictures, Wayne :D, just joking, great article, just got in and am mega pooped, I will finish reading it when I am a bit fresher. Thanks.

[LEADHOPPER]

I would be in for a 270 mold, maybe something along the line of the NOE 311165 design. I'm sure that it would feed fine in a bolt gun. 150-160 grain would knock the piss out of anything that I would be shooting at. Have the mold drop at .282 and we could size accordingly to our needs.

[Armorer]

Did the interest in this mold die out? I would definitely be interested in one if it comes to fruition. What say y'all? I use Lee push thru sizers so I reckon I would need to find someone to make me one in that style since I don't believe they make them. But that's the cart gettin in front of the horse.

Bullseye who is a poster of some reknown on this site will bore one out for you.

Buckshot is the famous push thru die maker..

D'Oh!

[Armorer]

Yes sir, I have been directed to Buckshot. Remains to be seen if I will be needing his services for this particular boolit mold though. Any other interest in this?

Armorer

[hicard]

Any photo of the proposed bullet? I am a little worried about a "large meplat" nose feeding in my 6.8 remington sp AR-15.

[Armorer]

I'm guessing it would look more or less like this.

This is the boolit mold referenced in the first couple posts of the thread.

[Gswain]

id be interested in a 150 gr, especially if its available in a plain base option

[Armorer]

Gswain, this thread seems to go in starts and fits. I'm not so sure it is ever going to fully get off the ground. I would definitely be in for one if it does. 140-150 Gr. Maybe by getting bumped to the top it will gain more interest. We shall see.

[LEADHOPPER]

This is what I am looking for in a 270 bullet. The shank of the bullet will fit in the neck of a 270 Winchester with the gas check right at the bottom of the neck. I get it at 150 with pure lead, don't know that density of Lyman #2 or WW, but I'm sure it can be figured out. Nose can be played with, I'm sure that chamber casting & impact impressions would help with this. But figured that this would be a good start. http://castboolits.gunloads.com/imagehosting/thum_119084e656ab16cbe9.jpg ('http://castboolits.gunloads.com/vbimghost.php?do=displayimg&imgid=2043')

[Armorer]

That looks good to me. I have the 311165 and it's awesome. A 3cav GC with one cav HP'd would work for me.

I like this!

but would like it heavier. minimum 160gr with WW, up to 180gr.
