Thread: 45/70 Subsonic

do the hollow point thing Bill....have a look at shootersnz .30 cal 151 grn pill....... in my humble opinion its just the ducks nuts at subsonic speeds...recreate it in .45 cal and it would be out of this world..

Hmmm his thread has got me tempted to buy a big bore rifle and stop passing round with a. 30 cal doing both super and sub sonic

That was bloody entertaining!

Yep, That's me with the rifle, . Rossi .45 here is my pp bullets, 420grs the ones that hit the bucket, my Sharps likes them, well one is allowed to dream.
, Bucket muckerupers.

last shots for the day confirming dialups with the last of the ammo . . shooting over my day pack

inside white square is 3 inches . . .



plan B if the 405grn doesn't perform at longer range . . . big long bullets just look right.



the numbers look good . . .

here is the 30 caliber 197grn. subsonic for comparison . . the big .45 has more energy at 700yds than the .30 at the muzzle

Not really a suprise physics sets the rules, double the weight double the energy. But double the velocity and increase the energy 4x adding a few fps to the 308 wont help much but you might get another 100 ft lb and still be sub.

ya dead right MartyH, not really a surprise that it would be more . . . but i kinda like to have a number to play with, even if its not the whole story.

gas checks arrived today



next job is work up a load for 1600fps . . . not even close to full throttle but plenty of grunt to 300+ yards, recoil calculator predicts about the same kick as a .308
only 1 problem, the usual story . . getting the time this time of year to get out hunting, this is my busy time.



the numbers on the 530grn. bullet at 1600fps are very impressive . . i might just have to get that mold.

if anyone has a 44mag subsonic load i would love it. (for a rossi L/a)

cheers

A quite managable drop at 300 and much authority at the business end

i dont have a problem with bullet drop unless my scopes run out of elevation . . . real keen to do some field testing to see what kind of authority we are talkn about.



Marlin has an older 6X Luepold i sent back to the custom shop to get German reticle, Target custom turrets installed . . click value is .5MOA
has over 100MOA of elevation . . . sits in Burris Signature rings with inserts . . . later a MK4 3.5-10 mil dot with M1 turrets on a custom canted rail will be going on.

All that energy is not of much use unless you want to shoot 3 or 4 animals next to each other's with one shot.
I have been shooting a few goats with the 458 socom subsonic up to about 160 m. The projectiles go straight through.

I'm picking mine up from SSRNZ tomorrow. I've opted for a DPT can because of the short barell that I have.

What's the best place to get the Lehigh projectiles from? Straight of their webpage?

Reloading international web site maybe?

i disagree . . . i will take more energy every time, its not enough is more of an issue.

the idea that all the energy must be used inside the animal, or you must have expansion etc etc heard it all before . . . it seems to me its taking the mindset of high velocity bullet techeque and trying to transfer it to subsonic shooting, there is a better way ( to me ) look to Big bore hand gunners who hunt, they operate at similar velocities.

use a BIG flat meplat and disrupt tissue, go for thru iin thru penetration, smash the shouldes, stop the lungs working . . . maybe you just need to hit them in the right place @Friwi or maybe Lehigh bullets, XTP bullets are good, cut the range down untill you get better bullet placement.

i have shot literally thousands of Goats and a few Deer with a mixture of .223s and also cast bullets at subsonic velocity over the years for pest control, using .30 & .45 calibers, tried a lot of bullet designs at close range to +200yds, thats my experience and it works for me, take it or leave it but don't try to tell me thru in thru penetration for subs is of " not much use " . .. did you notice a picture of a Fallow Deer at the start of this thread, that was flattened at 100yds . . Big bullets do that, in my experience, your mileage may differ !
