long range bullet decision

[1899]

Only problem with using any of the mono metals at long ranges is that they require speed to work. Once you start dipping too much below an impact velocity of 1800-2000fps, you are asking for trouble. True long ranges are cup and core domain.

Is that also the case with the LRX? I thought they were designed to open up at lower impact velocities too - which is the reason I was thinking of giving them a try.

Lower impact velocities with most premium bullets, mono metal or bonded is 1800fps.

The Berger 7mm/180 would seem to be a natural for a big case 7mm. With a case full of slow powder, these things will be nipping at 3000 fps from a 26" barrel chambered for the STW.

A good friend and incurable rifle nut (Rob for practically any shooter in Sask) is cranking 3250 with the 180 Berger out of a 28 inch Gaillard. That puts the STW up with some pretty rare company in a comparatively portable rifle.

as of yet nothing past 500 yards shot a white tail doe in the head at 465 yards thought that is was good at the time.

Well for head shots at 465 yards...I really have no suggestion.

not yet its a kreiger 1-9 twist it will finish at 30"

That's a long barrel, 26" works very well in a STW, and 28" can show little gains, but 30" is really long. Not sure if it would be a real benefit, or if the benefit would outweigh the extra weight and awkwardness of the long barrel.

What other components are you building your custom from? I built one, but its not a hunting rifle, pretty much just a steel rattler or paper puncher, but I have been considering another one in a hunting rifle again. I really enjoy the STW chambering.

I have used 168gr Bergers, 160gr accubonds and 145gr Barnes LRX's for hunting in a previous 7STW I had. I would look into using the 168gr Barnes LRX's if I put together another hunting rifle.

I agree, hence my use of fragile target bullets like SMKs and Amaxs for real long range shots. At that point however only standing broadside is the key.

I was under the impression that no has had the LRA yet, I have used the sirocco 11's in 150g for many years in 7mm rem mag, 7 mm wsm, and 7x57 AI, and have been very happy they have a BC of .515 so no that bad and more that happy with the accuracy but want to try everything in the 7 stw.

I got the LRA bullets at Rayner Shine from Lancer , Sask.

Here is my review:
http://www.canadiangunnutz.com/forum/showthread.php/987591-**White-Tail-added**-Field-report-on-7mm-RM-168gr-LRAB-Mule-Deer

Have you tested the 150gr Swift at long range? I have found that Litz's BC numbers are a more reliable place to look than at factory numbers. The only two bullets I use that have equaled factory numbers are the .284" 175gr Sierra Gameking and the .308" 200gr Partition.

After reading your post on the LRA results I am more convinced that the new LRAccubonds are going to be very good for extreme long range hunting since they seem to hold together better than the Berger Hunting bullets.

Its a fully tuned Remington SS 700 with a Kreiger #16 Plama barrel which is .75 at the muzzle 30' finished before brake if I decide to go that way, H-S precision stock,heavy duty holland recoil lug. Topping it off with a Nightforce 5-25x 56 ATACR scope.

You are correct. Barnes recommends a minimum impact velocity of 1600fps for the LRX, compared to 2000fps for most of the TTSX bullets.

Right from Barnes.

The LRX (Long Range X) bullets are flying out of here faster than we can make them. These are an optimized version of the Tipped TSX bullet and they have unique qualities that may make them better for you under a few circumstances.

An improved nose and boattail to be even more streamlined (higher BC value). This will again add to the distance you can shoot and still achieve bullet expansion. On top of that, we have lowered the minimum impact velocity to achieve expansion from 2000 fps (for most of the Tipped TSX calibers and weights) to 1600 fps for all of the LRX bullets. Again this will add about another 200 yds to your maximum effective range. In some larger cartridges this will allow the bullets to expand out to distances of 1000 yds or more.

Thanks - I was looking for something on Barnes' web site, but couldn't find it for some reason.

 

[kman300]

Barnes told me 1600fps water and 1400fps animal for expansion on the 200gr ttsx when I emailed them about that bullet.

 

[quarterman]

I would go with the nosler long range accubonds or a 162 gr hornady SST
