Thanks djones....that video is why I asked about humidity.....I fight it constantly using the thermals I currently have access to. I have to manually ‘nuke’ these, so humid conditions drive me batshit and eat batteries at a higher rate. I'm used to nights where I can’t see much but the emitters. LOL
Personally, I think 150s are too heavy for this class cartridge - they eat up too much powder space. I'd save them for 30/30 or above. I would not go heavier than 130gr or maybe 135gr. That's just my preference. About the longest bullet I want to use is a 125gr Nosler BT.
I'd give these a try. I can't recommend them expansion-wise, because MS doesn't tell you what they really are. https://www.midsouthshooterssupply.com/item/00285s30192/30-caliber-point308-diameter-125-grain-hollow-point-wcannelure-100-count-(blemished)
Here's some 135gr flat bases that may work. https://www.midsouthshooterssupply.com/item/00285s3027/30-caliber-point308-diameter-135-grain-flexible-tipped-wcannelure-100-count-box-(blemished)

I beg to differ with you on your opinion of 150gr bullets. Personally I've found 150gr bullets such as the Hornady SST and Speer Gold Dot to be capable of taking some very large game such as Elk, Kudu, Wildebeest, Waterbuck and Zebra. Also if you run the #s on one of the ballistic programs you will find that a 150gr at 2300fps shoots flatter at 200-250yds than a 125gr at 2500fps due to the higher BC.
Also the Nosler 125gr BT or AB bullets are not compatible with the 300 HAM'R, they have to much of their weight at the base and the ogive is wrong resulting is them taking up too much powder space and poor accuracy due to the long jump the bullet has to make to the rifling.
BW,
What are you considering too long a jump with the NBT's.
The shoot well for me with some very long jumps.
I don't have any #s handy, but all I know is if I load the 125 NBT to 2.255" I get 2-3" groups, if I take them to a belt sander and buzz the polymer tip off flush with the jacket they shoot sub-inch. I can only assume it's the jump to the rifling.
In the 150s, it looks like a flat base is the key.
A flat base certainly helps, BUT the Hornady #30303 150gr SST with boattail shoots very well for me and you can get 30fps more velocity out of it than any of the other 150gr bullets based on our pressure testing.

I would call that good test of your hypothesis.
Now that you mention it, dad trims the tips the 200gr NBT's in his .338 WM, and it that rifle, it helps tighten up the groups as well.
Thanks.
Have you know the H2o volume of your cases?
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

I have brass and dies on order. Can’t wait for the upper.

Sorry, I don't know the water volume, just that a fireformed LC cases and Sig mfg 300 HAM'R cases have the most capacity.

Removing the plastic tip would not change the jump to the rifling.

By removing the tip you can seat the bullets out thus reducing the distance form the ogive to the rifling and still fit the cartridge in a AR-15 magazine
The brother in law and his friend have had hogs run back to them sometimes when they bust the herd.
Some have been killed with a shotgun loaded with some number 1 buck shot that i cast out of wheel weights.
Have you ever had a double line up perfectly?
many times pigs run away from the sound of the impact of the first pig hit. they also tend to run back in the direction they came from. i've tried to get creative on steering them in the direction i want. then again, they can get just as creative and run right at me, lol
i was still shooting a 6.8 here with an armasight zeus. pig was pumping blood pretty good but kept coming. i was hiding a couple of rows inside the corn and they never knew where i was!!
as far as doubles go, yes i've tried that numerous times but only seem to get the first one. i tend to use destructive bullets and probably don't do much damage if/when they exit.
well... not exactly. i asked for 500 of the 125tnt for xmas. wifey means well but got the 130 hot core. even tho we all search for the holy grail of calibers, bullets, load recipie etc, for me it really doesnt matter. ive shot into herds with many bullets. sometimes they all die, sometimes not so many. decided to keep the 130s. went to load them and violá... i found 600 of the 110 spire points i forgot i had when i went to the 125s. decided to load them instead. the 110s are whats in the pic.
sorry dw. i dint see the late entry from as. looks like yawl are in a runoff for the free hamr. for the tie breaker, i will need each of you to submit an executive brief titled... why you cant kill a hog with a 223.
