300 Win solids

300 Win Mag 180 solids for your Tiny Ten:

 

[Firebird]

A great idea-who makes them and we’re you able to get them to shoot the same as soft points?

 

[Philip Glass]

Interested. I need to have some loaded for tinies. Advice?

A great idea-who makes them and we’re you able to get them to shoot the same as soft points?

Open the attached image and you’ll answer both of your questions.

 

[Firebird]

Sure enough

 

[AimSmall]

Cutting Edge Bullets.

...and used the same powder charge (RL22) as the Swift Scirocco.

Had great luck with these in other calibers, have not used the 300 on game.

In 300 Winchester I used IMR 4350 for the test work we did in 2024............

For 308 Winchester I used IMR 8208 and IMR 4064;

Pressures listed in RED is OVER MAX Pressures...... DO NOT USE...........

These are Copper and fall under Factor #3 of the 8 Factors of Solid Terminal Penetration.

#3 Construction & Material
Construction of a solid is a major part of its ability to penetrate. To deny this is foolish to say the least. Some of our solids out there, lead core, are very very weak in construction and absolutely do not have the ability to bust through heavy bone and reach their intended targets. I have seen and have in hand failures of these bullets from the field..... A shame as well, as some of these bullets are promoted as Dangerous Game Solids, and some of them flatten out like pancakes when hitting heavy dense material. Some FMJ Have steel inserts, while this solves a problem in one area, it creates problems in other areas.... Brass is harder than Copper... No surprise there, but I have busted elephant heads with both copper and brass, and never had one distort, but, these solids were of a very STRONG NOSE PROFILE as well........ So you see, combinations of different factors work together to strengthen or weaken other factors..... A good strong Nose Profile, can overcome some material deficiencies and in the case of copper solids this is extremely important.


Any Solid, Brass or Copper, can and will distort even in soft tissue at higher velocity Impacts. These 308 Copper Solids are fantastic, but at high velocity the copper will flow. This effects straight line deep penetration. The lower the velocity, in some cases, penetration is enhances both depth and stability.

One other tidbit of information, most of the bullets compacted, became shorter after terminals. Of some consequence for some applications, but interesting to note, and would not be much of a factor in the proposed use in this thread, tiny antelopes and other even larger animals if needed.....

Had great luck with these in other calibers, have not used the 300 on game.

For use on antelope and in particular the Tiny ones, this deformation will mean nothing and is a moot point, and they will perform outstandingly. Even on larger antelope+ I don't see any major issues in the field. Larger caliber Copper Solids have a bit more diameter and some less prone to deformation, but also it would be rare to run a big bore copper solid above 2600 fps........

These will accomplish the mission you are asking of them.
