How come there are no bullets out there for .338 .358 and .375
that are extremely low sectional density?

Such as 150 gr .338 or .358 or .375?

Seems like you can get 3000-3500 fps plus out of these larger bores with short barrels?

.308 type drop levels in a 10-12 inch package....

Seems like a gap in the North American market.

Poorly constructed Soft Points OTMs ect.
 
Demand and performance. Not many people looking for light for caliber bullets in non-varmint calibers. Most people consider 150gr on the light side for 30cal, nevermind 35 or 375cal. From a big game hunting perspective you want the weight for penetration, and otherwise you can always just get a smaller faster cartridge for varmints or targets.

Also typically when bullets are light for caliber like that they tend to be designed for weaker cartridges - 125gr 358 bullets are common for 357mag/38spl, but they aren't designed for 3500fps.
 
I feel like a poorly constructed 150 gr .358 or .375 would basically rip a coyote in half inside 300 meters.

Nothing can transfer that much energy like that.

I'm talking like a .375 RCM @ 3400 FPS.

Nothing would cause this much damage inside 300 meters.

Maybe I am overzealous on sub 200-300 lb poorly constructed mammals/varmints.

Like a soft lead jacketed 30-30 bullet design. But light.

It's against what everyone thinks and is doing. But it can replicate low b.c. 308 drop. Am I crazy or what?

Wouldn't it be fun to make larger mammals pop like gophers?

I cannot even find ideas like this anywhere. Not even in the U.S. Forums.

With modern powders and components. 0.5-1.0 moa should be attainable.
 
The 200gr .375 bullets shoot great out of a .375 H&H, but all the books say don't hit game above 2300 or so. on the high end they can do about 3200. The 235's can go about 3000 and they are a way tougher constructed bullet.

1) something like a 270win loaded with varmint bullets will wreck a coyote too - 3400+fps with a 110vmax.

2) watch bigger animals pop like gophers? That sounds kinda ####ed up. I hunt for food, for pelts, or to protect livestock, not to kill #### for amusement.

Totally get that about the effed up part.

110s in .30 and .277 are great...but not big enough.

I've shot coyotes w .30 cal 110gr VMax and the terminal effects are pretty impressive. They produce a ca. 4" exit hole and turn the insides into sloshy blood soup. I don't remember the muzzle velocity but it was over 3000 fps.

You are somewhat asking for the impossible. Lightweight bullets capable of being pushed really fast, won't have a high BC.

Incorrect.

A 3400 FPS 150 Grain lead and copper Partition coming out of a .375 RCM or say....a .375 WSM....will absolutely and positively have the same drop as M80 ball. (147 gr .308) .399 b.c. (16 inch SR25)

Speed overcomes drop with trash b.c. (.321).

Goes transonic at like 1000 yards more or less.

B.C. is kind of a meme inside 600m.
Sectional density is a meme on smaller creatures. Don't need it.

We are talking 10 Gauge slug blast damage here boys in an AR10 platform.....short barrel.....1 moa.

I would suggest you give someone like Dale Janzen a call at Chinchaga bullets and let him explain it to you .

235gr .375 speer is moving at 22-250 velocity from my 375 rum.

It also comes down to purpose for non standard weights. For example, a 90gr .277 bullet is going to be designed for varmits, penetration and even potentially disintegrating in flight are potential problems.

My concept was to bring the heat you have into a 11.5 inch SR25 platform.

150-180 grain .40 CT A.I. for example.

Massive speed due to bore. Low flash. High affect inside 600.
Outperforms 993 inside 300 meters with special loads.

Nobody is doing this.

Hammer Bullets or Cutting Edge is who I would talk to for what your after.

I have heard of cutting edge. I will look up hammer. Thank you.

Just looked at hammer. .199 B.C. is low for a 137 grain .375.

If you take a thick jacketed .260 gr accubond profile...fill it with a bit of polymer or aluminum....you now have.... .161 g7 b.c. varmint rounds.

Great for shooting anything at 3200-3500 FPS if you build it right.

High b.c profile....low grain....low i7FF....high fps.

7.92x40 style in 2023.

And what would you use this for?

Anything and everything.

Shooting appliances. Shooting and wrecking extra thick AR500 and AR600 steel. Pissing off Englishmen at the range. Shooting varmints. Shooting deer for meat.
Shooting paper. Shooting whatever.

For research and fun.
