Good morning Will. I took the liberty of changing the title of your topic a bit as it read like you where looking for a 300 Savage bullet.
The short answer is that neither bullet is a good bullet. I've always been a advocate that preaches that cast bullets are cartridge specific. Even though my two offerings are are 30 caliber bullets, they were designed for the 30-30 Win and won't make good 308 Win bullets. Claiming this, I took the time to put together some images to help explain why.
For starters, both of these bullets where designed to take advantage of the relatively long neck of the 30-30 Win and when the bullet is seated to match the throat of the 308 Win, the bullets extend quite a bit aft in the short neck of the 308 Win case.

You will notice that the bullet body on both designs are the same. The differences between the two are from the front band forward. These differences are to accommodate the differences between an original Marlin throat (the "A" bullet) and a SAAMI cut chamber (the "B" Bullet).
My experience has been that once you have the "tail feathers" of a cast bullet resting inside the case, aft of the neck, you will never see optimum cast bullet performance. Bullet erosion starts at the shot and the bullet will never be capable of matching jacketed bullet performance.
I did design a 308 Marlin Express bullet but I made a fatal error with it. Rather than letting the chamber dictate weight, I let the the buyers influence me into a "heavy" bullet. For some reason cast bullet shooters are always looking for a heavier than spec bullet and that in itself starts the compromise of a design.

A 308 ME chamber has a little more slop than the 308 Win chamber (so the bullet can angle in from the carrier) but fit is about the same. With the 308 ME, the bullet rests in the chamber with the gas check extending aft of the case neck. With the 308 Win, the body has entered the case. All of this is from "cramming" too much lead into a given area, the only place it can go is aft. This should have probably been a 150-grain bullet at best. Despite giving the customers the heavy bullet they wanted, it did not shoot well and I had to field the questions as to why it shot badly... "well, I told you it would not work". I only had 50 of these cut because I new it would not work.

My new 300 Savage bullet, the TLC310-150-RF, is the best fit but even it would be a compromise because it is designed for a different cartridge. At least it forms a base of for a 308 Win bullet in that the gas check base and case neck base fit. Notice with all the bullets how much case trimming would be needed to match the case mouth to the crimp groove.
So, the bottom line is that there isn't a "Ranch Dog" bullet that is designed for the 308 Win.
Al Nelson of NOE has asked me to help organize some new designs and after the first of the year I will have a presence on his forum doing just that. There has been some interest in both my 7.62x39 and 300 Savage bullets so a 308 Win bullet is to far out there. Al can respond with the tooling real quick compared to Lee Precision. I will mention this next week and see where it goes.
