is this attainable, or am I dreaming?

TedH · Post by **TedH** » Thu Feb 07, 2008 11:22 pm

I'd say not likely to do it safely. That's about all I can squeeze out of a 150 gr. load. Maybe some others know a trick.............

YOU ARE DREAMING IF YOU WANT TO KEEP IT WITHIN SAAMI SPECS IN A GUN NOT MADE TO BE PUSHED.

honestly, i doubt that you could pull that off safely. to get there you would need to convert your gun to a 30/30 improved or a 307. then you dont have reliable data.

that said, you might get 2325 or so with the leverevolution 160 grain factory 30/30 loads. It may be possible to handload 2350 to 2400 with 150 grain bullets.

My lee manual lists a maximum load of reloder15 at 2330fps for the 170 gn , so it would depend on whether your rifle can handle a higher pressure SAFELY. I you wanted to try you would have to work your way up very carefully and watch for any pressure signs.
Personally I wouldn't do it, I'd get a bigger gun.

has anybody used any of paco's loads

bsp, A velocity of between 2000 and 2150fps with a 170grn bullet is more realistic and safer. That would be using w748 powder.
I run my 307 win at 2400fps with winchester stated loads(170grn bullet). The 307 uses a bit more pressure and more powder, and asking this performance from the standard 30-30 would be pushing well beyond safe limits.

Let me re-iterate the salient part:

YOU ARE DREAMING

My question would be -- WHY??? A 170gr bullets being pushed between 2000 to 2200 fps is a pretty formidable round. Certainly enough to kill elk and lesser game along with bigger game if the conditions are right.

It's easy to obtain that velocity its called the 30/40 Krag

not the 30/30

a 170g slug at 2000 to 2100 fps seems to work just fine - I cannot see the big deal with extra 200 fps - more trouble/stress for any small gains of increased velocity

Bigahh · Post by **Bigahh** » Fri Feb 08, 2008 1:11 pm

I am trying to do just the opposite as you. I am loading the same bullet in my BLR .308, and trying to get it down to 2300-2400. I just need the weather to cooperate.

The trick is to rechamber the gun to .30-30 AI...

I recommend that if you want a .308 Win, you BUY a .308 Win. 170 gr. at 2200 fps will do just fine whether you believe it or not. Try it.

bsp, why friend?

JReed · Post by **JReed** » Fri Feb 08, 2008 2:12 pm

Why dont you just pick up a Lee Enfield in .303brit and have at it? 174gr @ 2450 is the standard Military loading.

Don McDowell · Post by **Don McDowell** » Fri Feb 08, 2008 2:28 pm

The Lyman 47 handbook lists a load with Rx12 that they claim hit 2349. I haven't been able to duplicate it in a standard 30-30.Rx 12 isn't available any more, and the Lyman 48 manual isn't near as enegetic.
Altho Hobie is correct in that the trick is go to a 30-30ai,then you can get there.

Don't abuse you're marlin. You want those kinds of velocities go guy a Marlin
308MX in 308 Marlin Express.

You will need a 26" barrel to get close.

william iorg · Post by **william iorg** » Fri Feb 08, 2008 7:40 pm

There is a thread on the Beartooth forum comparing the 16- 20- and 26-inch .30-30â€™s. Alliant Reloder 15 and Hodgdon Varget will surprise you with their performance but 2,350 fps from a 20 inch barrel is not a reasonable goal.

As a side note the .307 Winchester will exceed 2,450 fps with the 170-grain bullet from the 20â€

what makes you think that that bullet wants to go that fast?

I am guessing you may be a Cowboy silhouette shooter. I have done a lot of testing to develope a 170 gr. load that will reliably knock down a 56 lb. ram. Th best powder I found for velosity was R-15.I tested it in a 336A Marlin with a 24" barrel and got 2245 fps. without any signs of pressure. My Winchester 94 with a 26" barrel will turn up 2345 fps. also with no signs of pressure. I would suggest you start around 32.0 grs. and work upwards checking for pressure signs. I am using 34.0 grs. I must say this load will flatten any steel ram. It is also extremely accurate. I doubt you can achive these velositys with a 20" barrel. Also if shilouette rams is your motive, there is a rule change for 2008 that requires the rams to be set back on the stands to make them easier to knock down. cslcAl
