7mm-08 at 400m help

boxhitch said:
For 7mm.284 the 140 is middle-of-road for the caliber, results can be expected as with maybe 165 .308, or 225 .338
It might be suitable for the task at 7-08 velocities, or a heavier for caliber like 165 may perform better on skin but not have the ballistics
generally I like to follow the heavy for caliber rule with conventional cupand core bullets, but throwing heavies at slower speeds has its issues too.
175s at 280 speeds often have an exit, nice for tracking

ymmv

The OP is talking about a 140gr woodleigh bullet, which are bonded.

The only thing that I would think MIGHT be better long range bullet in the 7mm08 is the 150gr Long Range Accubond, Nosler says you should be able to get close to or over 2800fps with the right powder and that bullet is designed to expand reliably as low as 1300fps.

At 400yds the woodleighs should be cruising right around 2000fps, which is the minimum that woodleigh calls for, which to me means they're not quite going fast enough.

Sorry for the stray off the topic Rhys. Indeed, the 338 and the 300 Mag dole out some recoil, so they may be ill-suited
for your purposes. :) Dave.

haha you're all good mate. :)



Suther- Fair call too, iirc there seems to be pretty good reports from the woodleighs for the softness factor, i will take that on board and see what i find out., a cup an core would negate this in my opinion for the further than not , shots.

someone mentioned that what i use is middle ofthe road, an anything else may look good on paper but not offer the ballistics , or however they put it, is proberly on the money.
the only way to improve on what i have now, is simply more powder in the case.

i like the idea of a 7wsm for this... justto use the 7mm stuff, however in Aus the likeliehood of a 7 is slim an a 270 WSM would be my next best bet.

If an when i do this- iwill let yas know- moneys a little tight at present, spending it all on taxidermy supplies :D :D

leave it with me...........
 
To be realistic, ive talked abut it here before, in doin one of the kmber barrels to 284 win variant, bbut seeing as we are here, would the stainless 30-06 A bolt barrel, work as a 30-284 win ????

easier to geta A bolt barrel down the track for a 308-270-06 etc....... food for thought here but makes sense to me almost... i still have a 30 cal, i'll find brass , its left handed, and it can shoot say a 150gr at 3000?? maybe a bit less? sounds flat enough for me !

Friend of mine built one years ago. Like most 284 based cartridges if you put it into a long action you get slightly more capacity than the 06 based ones. Similar to the Rem short mags (6.5 And 350). A 30-284 in a long action should push 150's to 3000 fps. - dan
 
A .30/284 in a long action is just a short, fat, .30/06. Hodgdon uses the same load data for both.

Sounds like what you need, WL, is a 7mm Rem Mag. Kicks like a .30/06 but shoots flatter.

yeah mauser, i think this is ringing true-- thanks fellas!

7rm ammo is expensive down here, cheapest is $50 for 20... crazy-

reload option only for me..

I regularly exceed 3000 fps with a 150 grain bullet in the standard 30-06, so no new news there. Dave

Now you have the following at your disposal: 140's at 3250, 150's at 3150, 160's at 3050. :)
My 7mm Rem Mag will make 3100 with the 160, using Reloder 26. Dave.

i normally use ADI but i think for this magnum i will look into reloader25 ! woodleigh manual gives a few types of powders
prob use 139 hornadys for practises first

This is a "practice" I really don't understand.

Why would you use a lighter bullet, especially a different bullet to practice with, than the bullets you intend to hunt with???

I've seen others do this and it's mostly an effort in futility.

Keep the 139 Hornady bullets for your 7-08 and use 160 grain bullets of similar design to set up your rifle for the final zeroing of the 160 grain Woodleigh bullets.

BTW, I'm not a great fan of Woodleigh bullets.

Not because they don't perform well on the intended target, as far as expansion/retained weight goes, but because they aren't manufactured to be extremely accurate.

They are accurate enough for most hunting situations, out to 300 yards. After that their limitations really show up and so do the limitations of most shooters.

I've also noticed that many hand loaders have a very difficult time getting them to shoot well in their rifles and that's also been my personal experience with them.

This is just IMHO, coming from personal experience and observations. You may have far better results.

IMHO, there are bullets available to you that are much cheaper and easier to get to shoot consistently well and perform acceptably out to and past the ranges you want to shoot at.

mostly to limit the amount of money i put into a dirt bank for no real reason, play with loads, get it 'sweet' , shoot the hell out of it....

load up hunting rounds, set the target a 300- 350-400-450 , shoot, confirm, hunt.

thats why Fella.... you guys might of picked up i dont work ya normal 9-5 lifestyle, And i dont hunt for 3 weeks a year, so if i can save $100 dollars on projectiles, oh i will.


will look up an into a heavier 150-160gr projie in time, down under we dont often get 2 or 3 shots at the game at the distances, they normally poke out thru gaps in the bush etc, so i dont think it really matters much about a 3x shot group under an inch at 300 meters however knowing its trajectory is in favour of landing where intended should be of great ppleasure

Load the round you intend to hunt with. Use it, save money and time from developing new loads, along with barrel life. Switching bullets, buying more powder, wearing out a 7mm RM barrel is more expensive than $5.00 per box for 160 vs 130's or whatever. A group of 3 shots that are great only means your first one will be great as well.

Considering the price difference between cheap ~140gr bullets and cheap ~160 gr bullets, I'd figure out what bullet you plan to use on game and pick a similar weight for a cheap bullet to practice with.

With the known purpose of long range Elk-sized animals, something like a 160gr Woodleigh sounds like a great choice - its no Long Range Accubond for BC, but its not terrible either (0.486 they list on their webpage, which is slightly better than the 160 partition BC of 0.475 published by Nosler) and with a muzzle velocity of 2950fps Federal says the 160 partition is still going 2040fps at 500yds (which is 457 meters in everywhere but America, Myanmar, and Liberia...)

Similarly, the 140 partition and Woodleigh have nearly identical BCs, and Federal lists a MV of 3150 and a 500yd velocity of 2122. The difference in wind drift @ 10mph is not much, 18.5 vs 18.2 (140gr vs 160gr bullet)

It should be noted the velocities listed above by others exceed these numbers by not insignificant amounts as well, so even if you can ONLY get to the mild numbers listed by Federal from their ammo using the Partition bullet as a stand-in for the woodleigh, you should be good out to 450m with either the 140 or 160. Long story short, pick what weight you're going to shoot at the game, and get practice ammo in a similar weight, because theres no good reason not to IMO. Any difference in recoil between a full house 140gr load and a full house 160gr load won't be significant enough to matter IMO, one is heavier but the other is faster so in the same rifle it wont be a big enough difference to be worth screwing around with multiple bullet weights.
