Home Forums Hunting & Shooting Hunting Rifles T3 Superlite 7mm-08 and 150 ELD-X experiment

I bought a Superlite awhile back just for fun. I already have a stainless T3 7mm-08 that I use for everything but I figured, why not. When Hornady released the 150 ELD-X I decided to turn the Superlite into a long range shooter.

I swapped out the SA bolt stop for a LA stop so I could seat the bullets into the lands. The original setup gave me 2.835" OAL, with the long stop and a .30-06 mag I reach the lands at 2.987".




Hornady suggested I use Nosler's data for the 150 Partition with Hunter powder, which I have a bunch of. I loaded a few at the max charge and shot them over a chrono. They averaged right at 2800 fps with no pressure signs. I loaded 6 each at 4 depths, starting just kissing the lands.



Maybe a range day tomorrow.

I would think the Nosler 150 ABLR would be another good High BC bullet to try in the 7mm-08.

I have read of poor bullet performance with ABLR bullets.

Pharm...I'm interested in the outcome of your 7-08 L.R. Project,those long 150's stickin way outta that brass is cool...ScottyO

I'll be watching this one closely.

Me also. Been trying to put one on layaway at Whittakers to no avail. Still interested in the results.

I loaded 6 each starting at 2.318" (measured from the ogive with a Hornady Comparator), then 2.279", 2.239", and 2.197". The shortest length still exceeded max mag length using the 7mm-08 mag.

Nosler says 49.5 grains of Hunter is a compressed load. There at the end I could sorta feel a crunch, but Hunter is pretty fine.

I'll keep everyone posted.

A good friend of mine shot a bull elk a cow elk and a pretty nice mule deer. Maybe not a large sample but he really likes them in his 280AI.

That said I'm very interested in you findings.

Can't wait to hear the results

I'm surprised people are not reaming these out and making a 280 AI on the Tikka action.

Here's a question for those with more experience. This rifle is new, the chrono loads were the first I've shot with it. Should I expect accuracy to change the more I shoot?





P

I hit the range today, 37 degrees and calm. After boresighting and getting on paper at 50 yards I moved to 100 yards and set up 4 targets. I started with the shortest loads first, and got the best accuracy short.

The second-shortest load showed the most promise, coming in at 0.82" in 5 shots.





The shortest load looked okay, coming in just under an inch.




I think I'll try a couple hundredths between the two loads.

I'd bet typical SA length would be money, if the powder/pressure allows.

2.806", as measured from the tip, is money for 120 BT, 120 TTSX, 140 PT, and 140 AB in my other T3.

New Year's wish...please lord...bring back the 284 win w/1:8 twist and make lots of brass!

One of the guys that used to post here did a 284Win. on a rechambered 7-08 Tikka, using a long action magazine and the modified bolt stop.

Seemed like a nice way to get there, and with 6.5x284 brass available there's no issues getting brass either.

Thinking 9 twist is enough for anything you want to spit out of that case. It will spin the 180s no problem.

FWIW, I don't think the 280AI will clean up the 7-08 chamber without a lot of setback.

I saw ruger is doing a special run of tan camo cerakoted Americans for Jerry's Sport Center... 708 is listed as having a 1 to 8 twist....tempting....lol!

They're learning...

I've yet to witness it !
