Linotype 9 mm speed question

[c east]

Have 30 year old Linotype.124 grain I am reloading with 4.5 grs of red dot and they are 925 fps 10 ft from muzzle...I use to shoot 31191 's at 1400 fps with no gas check..... with no leading.....Used tamarac lube........I am using Lee alox 2 coats...no gas check....IDEAS ON LEADING PLEASE......Using Brown HP....Charlie

What diameter are you sizing to? Of if you are using Alox are you shooting as cast? What diameter are they dropping from your mold?

[Shiloh]

Mine are sized at .358
No leading at 1200 with 50/50 range scrap/WHeel Weights. Considerably softer tha what you are shooting.

Not sure if the alox will stand up to higher velocity. I know NRA 50-50 (your old lube) will run
WAY past that vel. Hardness has relatively little to do with this. Fit, lube quantity and
lube quality are what will help or hurt. Use .357 or .358 diam for 9mm in most guns.

Sized .355...I have no idea of out of mold size as I haven't cast in years.....

[MtGun44]

For most 9mms .355 is an invitation to sideways boolits, leading and inaccuracy.

it's be a guarantee in any of my 9m's at any velocity.

Chuck them and recast them.

Ask me how I know. Mining lead out of the bore, and have my pistol pattern at 50'. Sometimes even missing the target completely.

Put 20 on target...same as 124 gr XTP's with 4.5 grs Reddot...I'LL put 30 more on target and call them good if leading is OK...I have a bunch I coated with a liquid Molybdenum Disulfide that would dry and when sized would just get smooth... It all seemed to stay on..They called for no lube...Quit using it because of health warnings.....I opened the can and it still looked the same after 32 years...I'M going to load them up for some cheap shooting thru a 9 mm Mac 10 squirt gun...The Browning slugged out at.354 with a lead ball..This was an after market barrel so, I don't know how they normally run ..How do you guys slug them out?

bout the same, but start with an oversized lead ball.

Make a series of dummy rounds, starting with an unsized bullet, then .359", then .358". Use the largest size that chambers at the OAL you wanna use.
