i am very happy with the noise reduction of the DPT as it is . . . so often ya hear how loud the big bores are going to be compared to smaller calibers ( obviously theyre going to be ) but personally i think its overstated, maybe their expectations were to high to start with . . . would be interesting if someone would keep adding baffles to see how it would go.

i can remember Greg showing me the 405s he had . . . look forward to getting your opinion on how they go on paper & animals

also look forward to how the scope works out . . . R

I wanted to ask this too @rossi.45 . Using subs is it hearing safe or you still need hearing protection?

Poured some lead this week into the new to me RCBS 405 using straight WW. Was surprised to get projectiles in the 428-430gr range. Wasn't expecting this much difference compared to #2 alloy. Couldn't check diameter as my son used my digital caliper as a hammer to bang a nail back on the deck so its poked now. Toddlers and precision tools aren't a good mix.

@Boar Freak i would describe the noise levels when i am aiming away from bush or anything that will reflect the noise as a booomff sound, not much louder than my .30 caliber subs.
definitely louder in the scrub or aiming towards a hillside etc . . . but not annoying or troublesome to Dogs who are use to gunfire.

never checked the weight of any bullets . . . i have a good casting techneque now and close inspection of every bullet sorts out the obvious problems, if they dont look perfect they go back in the pot . . . if i was going longer range i maybe would.

your Son sounds like a rascal . . . bless
lets hope the bullet is at least 1 or 2 thou over groove diameter

look forward to hearing how you get on with the 405s . . . . it is one good lookin bullet

I stood, waited, stroke of twelve at crossroads
Song by the 'Kongos' played to my fear
'Come with me now' 'Come with me now'

Ready to sell my soul tonight, perfect cast bullets my sought plight.
But just as 'they' said, the Devil wouldn't even take a Bite.
"Where's your guitar ? I've brought mine - boy- lets play.
I'll make thee the best there is for thy soul.

It's not for to play that I come here tonight but perfect bullets are my trade.
"Perfect bullets for a soul... in this box you might find..., but sign you must before you look!"
Just in time decision not made,
Elmer is my Proctor
I turned and walked away

oh great and wise ones I hope you dont object to me injecting my humble opinion on your findings????
I do not own one of the great black hole barrels like your most worthy selves merely a humble chinese made rifle in a cartridge designed by a russian fella for to be made by the people ofr the people to kill the people...but maybe that would lead one to think of its big brother round not the humble x39 I cart around....
Ive tried many supersonic rounds and yip at close range they do the job no complaints
my subsonic loads use Roberts great 151grn hoho hollowpoints which look and behave pretty much like the before mentioned winchester subs...which reminds me you DONT need to melt .22lr rounds down to find hardness...it can be done with pencils from the stationary shop..... different hardness pencils will and wont mark different hardness cast lead (google is your friend)
because I dont have access to goat shooting 90% of the sub loads fired have either been plinking or hares...with the important/relevant ones being to kill my house muttons wandering around in paddock 30-50 yards.... to gain expansion/limit penertration I used old school trick and got out stanley knife and cut four slits down the tip /devided into quarters if you like... about 3-4mm deep/down into projectile sides..... so far Ive only managed to recover one and it measures 14mm wide so close to double diameter.
it will work with the 44mag moa hunter mentioned before but the law of unforeseen circumstances comes into play and may indeed OVEREXPAND at high velocity.you could also insert/glue a single steel shotgun pellet into cavity to assist expansion starting(#2 works perfectly in 151s) the theory isnt new as its what the fancy plastic bit on ballistic tips does.

ordered these 2 molds today . . . the 360grn. (left) is i think about as big a flatpoint (meplat) which is practical for feeding in the Marlin, time will tell, may have to single feed . . . the 405grn. (right) is the backup plan, both will be paper patched.

these bullet designs are closer to my idea of ideal . . BIG flatpoints to smash into the animal with enough weight to drive thru the animal from any angle, no expansion required . . we will see

@rossi.45 you may have mentioned earlier in the thread but cant seem to find it, what sort of alloy are you casting with for your wide meplat bullets?
Assuming your having good success with little expansion the alloy could be quite hard?
Thanks

at the moment 25% wheelweights / 75% pure lead

ramble alert.

i dont look or plan for expansion with cast bullets anymore, its a deadend road to me . . . the question is why i wouldnt want expansion when it sems to be a mantra to so many shooters

the easy/quick answer is its not worth the effort and the choices you end up making to get it for the animals i target at the ranges i want to shoot out to. . . better to rely on more reliable/repeatable performance with good bullet design, accurate bullet placement . . . thats the direction i am travel in, so far its working OK and i plan to run with it for awhile longer and see where it goes.

This is only a three year old bull, a really big mature one will go 7 feet at the hump

Bloody hell,!!, where's my Sharps!!.

poohseventy with 170grn speers-------.308 with 180grn maybe????
in shadow of horn or....... level with same JUST right of the light coloured fur where it goes sort of chocolate like but is still long??????
yip the sharps would just feel right/correct.

12gauge with solids...

416 rem mag. don't know whether solids or softs

i know how big they are face to face . . . back in the day when visiting an animal park a BIG old grumpy Bull Bison took exception to me looking at him, wanted to get thru a fence to get at my mothers youngest son, very impressive animal, surprised how tall they were.

but . . . they're not bullet proof
watch this clip if you want to see a .45/70 with 405grn bullets do the business

. . . or even arrow proof
