I picked up one of these molds new. My las experience with a bore riding bullet was not good.
Should I cast this one from straight linotype to keep the nose within range.
I will be trying this boolit out in several 30 cal firearms.
Thanks in advance!

no.
try cutting the linotype in half with pure. [or 3-1 with ww's]
keep the velocity's in the 17-1900 fps window.

RCBS sil moulds are spec with linotype alloy , my 165gr sil will cast bullets that can be sized @.309 dia with 15 bhn alloy . its a tack driver in my guns

I have had great luck with RCBS 165 SIL cast from ACWW, which produces a bullet .300 on the nose. I don't think you will need linotype to get a bore riding nose with this bullet.

I shoot this bullet in the following rifles and get excellent results in them all.

Two Winchester 88s in .308 W
A Savage 16 in .308 W
A Remington 700 in .308 W
A Winchester 70 in 30-06
Two 1903A3s in 30-06
Two US 117s in 30-06

I've had great results with the RCBS 165 SIL (WDWW) in a TC 32/20-10". I was shooting IHSMA production and standing classes with this round. This took down targets out to 150 meters reliably. With 200 meter rams, it would ring them every so often.

My smaller .310 bullet fills out better and shrinks less using strait linotype.

Linotype metal is loaded with antimony crystals, which do not melt, but remain in suspension in the matrix metal. Antimony has a couple of properties that set it apart from lead and other metals.

1. Antimony expands contracts when hot and expands when cold, just the opposite of lead and other metals. This was helpful casting small type letters and it produced good sharp and hard type for printing. The same characteristic makes it produce well rounded out bullets that tend to be a smidge larger than bullets cast with lower antimony alloys. For the bullet caster this is good.

2. Antimony also is considerably more abrasive than lead, tin and other common bullet metals. This will cause throat and barrel wear sooner than lower antimony alloys. For the shooter this is not good.

Linotype has it's place in bullets casting and that is to add antimony/hardness to other alloys. Thus it's best use is to add to softer alloys. A mixture of 50/50 pure lead and linotype will produce an alloy of about 15 Bhn. or roughly equal to No. 2
