Bottom line, in a good rifle, is a 277 speer hot cor going to be accurate enough for deer to 300 yds. every time, assuming the shooter does their part? I am talking first line bullets, not blems or seconds. I have some and the lead tips are a little more ugly than sierra or hornady.

130 gr. Hot Cor

Easily. A Hot-Cor is a deer hunting bullet. Makes no difference how pretty the point is either. Only the base of a bullet matters. The cartridge used matters a whole lot.
Using a .270 Win, with a MV of roughly 3060 FPS, at 300 it'll be going about 2259 FPS, but more importantly, it'll have about 1472 ft-lbs of energy. Sighted in at 200, it'll be 7" low at 300.
A .270 Weatherby with 3200 FPS MV, will have 2520 FPS at 300 with 1835 ft-lbs. Sighted in at 200, a 130 will drop 5.9" at 300.

I have shot the 150 gr hot-cor our of my 270 and gotten excellent accuracy. I know you asked about the 130 and I am sorry I do not have experience with them. However, i have been pleased enough with the accuracy and my own milk jug test using the 150 gr that I am loading them for this deer season.

They're fine.
Don't let the marketing for modern bullets impair your judgment and dilute the reputation of the classic designs.

If you do your part, the results tend to be spectacular one-shot-instant-kills on Deer.
Dvdcr,
Not just the shooter and bullet, but the rifle needs to be able to do its part, too. No dinged crown or other major issue.
A badly dinged bullet tip will lower ballistic coefficient a little, but it's not something you'd really notice much at 300 yards or less. It will also slightly unbalance the bullet, but when Harold Vaughn did his experiment filing bullet tips at 45°, the amount the group opened up was only about half an moa at 100 yards, IIRC. By comparison, a mere 2° angle on the bullet base had several times that much effect. Hence Harry Pope's admonition over a century ago that the base steers the bullet.

IME the HotCores tend to have tips which are a bit more blunt than Hornadys or Sierras - if that’s what the OP means by “a little more ugly”. Does he mean that the Hornady and Sierra bullets are less ugly? Words matter, communication is tough without a clear understanding when you ask for help.

A note about Speer Hot Core bullets...when they first came out (yup, I am that old), they seemed to infer that the lead core was somehow bonded/fused to the bullet jacket. As an experiment, I took one (caliber and weight lost in my memory), stood it on end and split it using a hunting knife and lead hammer to see if the core was indeed bonded to the jacket as they seemed to infer. Long story short, when the bullets were split lengthwise and no mechanical hold on the cores were possible, the cores fell free of the jackets. To me this meant that they were just standard cup and draw bullets.
Admittedly that experiment was way back when they were first introduced and I cannot say that they are the same today, but someone may want to repeat the experiment with Speer's current production just to see.
