Home Forums Hunting & Shooting Hunting Rifles 7mm-08 Tikka to 284 Win

Has anyone sent off a Tikka 7mm-08 and had the chamber cleaned up to 284 Win? With the action size, a long action bolt stop, and long action Mags it looks like a fella could take full advantage of some of the longer 162/168/175 class bullets. With new Lapua and Peterson brass components would be easy. Any idea on how well it feeds from the single stack mag?

Interesting project, but not something I would not do to a perfectly good Tikka. The 7-08 is a very good chambering. Seems the gains if any to go to 284 might be small compared to the problems likely to be encountered.
Have a stainless Tikka in 7-08 that feeds and groups very very well. It certainly meets my needs.
Let s know how your project works out, good luck!

Goat Fhuqk. RPM rates a thunk. Hint………..

Hummm, goat fhuqk is correct

284 can fit in short actions like 7mm08 and 6.5 Creedmoor do.

So instead of the factory 1:9, Go with a 1:8?, that would let me give me access to 180+, Id probably also want to AICS bottom metal, too



Can, but is handicapped by mag box constraints. I'd rather load the long boys way out and save case capacity for powder, not lead.

I've contemplated this for a while, think it would be quite a nice setup especially in a lightweight Tikka. You might try using a WSM magazine.

The 284 punches a good bit better than the 7mm08. Hence why Melvin Forbes light rifle conversions used it so often. Great overall cartridge with the shooting champions to prove it.

About every 6 months over the past 30 years, I get an itch to build a .284. This lasts for a few days and then I come back to the reality that the 7mm-08 does anything I need done with a 7mm.
Of course, I keep getting the itch because I never scratched it!

I fell into a 7x57 Montucky,that you know well. Hint.

With multiple 6-284’s,25-284’s and vanilla 284’s in the larder,all are an easy pass today. Hint.

The Teeker 7-08’s have long been 1-10” and that’s more than a little funny,on an “06 receiver. As RPM goes,they’ve long been a Schit Show. Hint………..

The 284 was designed to work in the short action Winchester 88 and 100 rifles, however you have to consider the following:

The 284 has a case length of 55mm, compared to to 51mm for the 308 family, and 48.77mm for the Creedmoor family.

If the 260 REM's 51mm case length causes COAL issues with longer, heavier, bullets when compared to the 6.5 CM, another 4mm of case length only adds to those issues.

I have short action rifles chambered in 25-284, 6.5-284, and 284. The all run into COAL issues with longer, heavier, bullets due to the magazine limits.

If you're want to maximize the velocity potential of a short action 7mm cartridge, why not go with the 7mm SAUM or 7mm WSM in lieu of the 284? If more velocity is the goal, both of the short magnums offer more case capacity and the associated velocity potential than the 284.

Their site's showing 1:9 on the superlites, I haven't grabbed one off the rack for a looky-loo to see if that's truly the case. If they have sped up the twist then maybe they're listening, too many manufactures are too slow to realize they're too slow. What I like about some of the new hornady offerings, they twisted right for fodder they'll be fed

Man, how cool would it have been if they just 8 twisted them devils..

I think that would be a decent idea across all manufactures and bores, make 8 about the slowest and have a 6 or 7 on the little diameter stuff

The “jump” from 1-10” to 1-9” is fhuqking hilarious,in this day and age. Doubly so on an ‘06 receiver. Hint………..

What's worse? A cartridge designed in 1963 or people not understanding that when the 6.5 Creedmoor was released, .284 bullets all over the world immediately started bouncing off deer? Stick is here spending several hours of his EXTREMELY VALUABLE TIME every single day trying to educate you about what it takes to kill animals at 1000+ yards. AND YOU JUST ACT LIKE HE'S WASTING YOUR TIME?!

At 300 yards in semi-temperate zones averaging less than 14 inches of annual rainfall within 250 miles of the Tropic of Cancer, a .284 150 grain bullet is going to drop 214 feet and carries less energy than a slingshot. Back in the mid-70s, I worked with a cattle outfit in Wyoming. The foreman was famous in all the surrounding counties for running two 1200cc Yamaha saws at the same time. He would duct tape a saw to each arm and walk through the woods twirling like a cyclone. Anyway, he knew the checkout guy at the local feed store had a .284 but refused to put neon tape on the scope. Guess where it ended up? IN THE CREEK.

NEVER STOP, STICK! KEEP CARRYING THE TORCH! SHOW THEM PICTURES OF THE MAIL! IT'S THE ONLY WAY THEY'RE EVER GOING TO LEARN!

A 284 win built on a short action will not work well with heavy bullets as you have to seat them too deeply in the case to fit in the magizine.
The big bullets take away powder capacity that make the caliber special at longer ranges. You are not gaining much over the 7mm/08 in a short action. 150 gr bullets are as big as I go in my Win. model 88s. If you want to use 175 gr or bigger, I would go long action.

It would be cool, but keep in mind the velocity wouldn't be spectacular with a 180gr or similar weight in a 7mm-08. Kind of pointless to twist it that tight, if you are probably only going to run 140's. I've tried 162's in mine and got pretty disappointing velocities out of it. Accuracy was stelar, but....I digress..

I’m using 162 ELDs in my 7-08 for 2700 this year. They seem to float to the target. No fur yet though.

The 162 ELD is a nice pitch,but still shy of a .264” 147 ELD. Hint.

Reserve RPM has never hurt the Killing Equation and it’s always nice to hear Melting Snowflakes Whine about wares they’ve never even seen,let alone used. Hint……………

You're darn right it is, Stick! NEVER STOP. NEVER GIVE UP. KEEP TEACHING THEM! If that means showing your mail every single day, show your mail every single day. If that means showing the same forkhorn buck from 12 years ago, SHOW IT! You can lead a shooter to the creek but you can't make them throw their rifle in.
