Yep starting to get on top of my .416 Barrett. †Smiley

It's a bit tough having to make it up as you go along though †Wink

But who can argue with 200 odd grains of powder making 400 odd grains of bullet go 3300 odd feet per second. † †ShockedCool

The recoil isn't to bad either †Cheesy

But the muzzel blast is a different story †Grin

Considering a 257weatherby magnum. I love 25 cal and I love all the people that hate it. Any other quarter bore calibers to consider?

The guy's in the states have shot 2500-3000 yards sub moa.
One has shot Mule deer at 2000 plus 3 times one shot kills, but it would take quite a while to get there so who knows how quick they died.
But they are legends & I'm just a Kiwi boy with a home made rifle. Smiley

Some of the advertised BC's are not necessarily the true BC.
The factory rounds have a "BC" of .9 ish but the BORS unit uses .73, so a bit of a difference there.
435gr "1.058" brass
420gr † †".95" †brass
416gr † †".93" †brass
410gr † † .81 † jacketed
400gr † .392 † TSX
I haven't shot enough long range yet to check the BC's but I have shot the TSX to 750 & the BC was about bang on.
But man do they slooow down quick & fall out of the sky , they suck for long range duty Wink
Thats probably because they are cheap, easy to get & they shoot well under moa in my rifle †Grin Grin
The brass ones are most likely no good on animals unless you hit a substantial bone. They just pencil through much like an arrow with a target tip I've been told, buy a guy in the states. †Sad

Its funny, I've it had up at a public range a bit lately and the usual response starts with F followed closly by a few more once I fire it. Grin Grin

Wow a 416 Barret...now I thought a 338 Lapua was a freakn canon and a half. I've set my sights on something a whole lot smaller.
I'm having a lightweight 6mmBR built on a Remington Model 7 action for longish range small game busting as we speak.

Hey Greg thats a pretty wide variation on BC.

Are the brass ones solid brass and I guess lathe turned? If so much longer for weight than a copper jacketed lead core so would make sense.

I reckon a few of us would like to see a photo of a line up of both the projectiles and the loaded rounds if you could post one. †

Interesting!

Didnt they have the Navy seal hero shooting one on future weapons?
Dont think it was a barret system but he was grouping well on a target 2500m away the size of a laptop. Shocked

I haven't regreted the AI at all and to date are up around the sixth fire and getting to the stage for a FL size to bump the shoulder back and at full length so will need a trim soon and these are with hot loads Wink

The 22-250 used to have trim the length every or every second fire when using the hot loads... Roll Eyes

1:8 twist  Cheesy be able to run some high bc pills with that Smiley

Yep the Brass ones are solid turned projectiles from 51 to 55 mm long.
One day I will figure out how to post pictures & when I have got it going properly I will do a thread on it.
Currently I have discovered my fancy brake is most likely a fancy piece of stainless scrap †Angry expensive scrap at that. Angry
But more testing tomorrow will confirm that before I email the maker in the States, I have a different one coming with some more projectiles so hope fully that will sort it.
The recoil is quite savage without the brake †Cheesy

Your right you shouldn't †Grin

No change & would have cost a lot more if I hadn't made the stock †Wink

I think it's quite cheap for what it is able to achieve.
@ 14 kilo's it's not a carry around rifle, but I didn't make it to be one.
If you can shoot 1500 plus you probably don't need to carry it too far †Cheesy

Greg, this from the Photography section may help you: http://www.fishnhunt.co.nz/forum/YaBB.cgi?num=1236226062

Suggest you print it out to refer to while loading them. If you need any help with photos from here on feel free to ask!

Maybe you should talk to Robbie Tiffen about that muzzle brake, also if Nelson Collie of Invercargill area is still around talk to him. he used to build .50 BMG cal rifles and they would have had a brake.

Walker,
Yes I considered the 6mmBRX but the gunsmith thought it
probably wouldn't feed that great from a magazine. I figured
if it all turns to shit and the standard 6BR won't feed I'll just fit
a benchrest follower & then go BRX for an extra 100fps.

I thought it was a mirror of the case but slightly longer in the case body but shorter neck so same OAL and diameter in fact you can neck size and bump the shoulder back with the same die....or that is as I read the articles Smiley

Actually I was asking about the range finder.
I know well myself how much the rifle would have cost I have been down that road myself with the 7mm.

Till I master the 7mm out too 1200 I don't see how I could afford the next step up. I figure with 2 target rifles and the 7mm thatís enough custom rifles for now I also have 3 rem 700 in 243, 260, 308 this completely fills my cabinet. I'd guess your set up dug in at 1500 would be worth 1/2 of all mine put together.

For that reason alone I truly wish you every success with that big rig.

What soft ware are you using to crunch the numbers? I purchased Precision Shooters Workbench over the net and I must say it bloody good. Awesome back up the numbers work.

the Swaro's are approx $2300 ish, there is one on Trademe for less at the moment.
I have Exbal for the PDA but I mainly use JBM at home

I also have Exbal at home. Although the differences between Exbal and Precision shooting are small let me know if you feel you are off, at say 1200 onwards as there are some reasonable differences out at that range and you may well be better off to change.

Precision seems to get it right more the time all of the time (Put bluntly spot on no question).

With my target rifles I could never get Exbal to calculate exactly for the ranges 300, 500, 600, 800, 900, 1000 there was always a .5 moa difference so I regularly lost 1 of my sighters since I change over the problem has disappeared.

No your quite Right Leathel....I asked Harvey Westland the same thing.
He said that he always found the improved variations of the BR case caused feeding issues on the Remington...I didn't bother asking
why as he's built more than enough to know.

I'd take that with a grain of salt. Suspect its more to do with having to spend money on a reamer, after all a remmy will chamber a 243 win thats nearly half inch longer!

Go the fireball, heaps of our HMS rounds are based on it and it is very accurate and efficient (as are all its progeny esp. 7mmJI).  I have mucking around with a .17MachIV/.17Fireball and it is an amazing little round (all the local .17HMR shooters are now considering changing-as the cost of reloads is cheaper than HMR factory rounds).  My current project is either a .250 Savage or a 6x39 for my 9 year old son to shoot deer with, he has proven deadly on the goats with the .17MachIV but I don't want him using it on deer, the .223WSSM has too much bark for him and the stocks on all my other rifles are miles too big.

I'm working on a 35 Whelan and a 338-06 at present. Both based on mauser actions , both 22 inch barrels and synthetic stocks.

Just waiting on a scope mount for the 338 and we will be shooting....
