If one chambered 3030 in a falling block 22-23"tube, what velocities could one get with 150-165gn?
I see win. has its supreme 150gn30/30 at 2480fps,so must be good for more poke than that in a falling block!
just looking at rounds that offer good case/bore efficency to minimise recoil, but offer good power/range/frontal area.
I figure 3o-3o150tsx/mrx in a falling block aint a bad combo.
Also like 6.5x54MS necked to 7mm 140-154IB or 140mrx.to give you idea of how im thinking.

150mrx-tsx

The probles is 30-30 brass it has a very week base if you want to go fast get a 307 or make 30-30 brass out of 375 winchester brass. I use 375 brass for my 7-30

Tom,
looking at 7-30waters, thats a nice round also as is 3o3oAI.
Dont want to go to 307win thats too much. std.3o3o on 375winbrass might be enough.
About the weakness of the 3o3o case, dont know much about it, but when I had a freedom arms 454casull I tried 45colt brass, and loaded it to the hilt 31.5gn296-300gn jacketed 1750fps65000psi?... I tried all I could to blow a 45colt case, didnt happen! Id like to see what 3o3o case will take & luckily, I have the 375win case to call on.
Some AckleyImp. data shows 2600fps150gn,from lever gun presumably. I guess std.3o3o-375win brass150mrx, in a falling block should get that.If I can get,
-180mrx@2300 will give 2000v/1600e@200yd.
-165mrx@2450...2100/1630@200yd.
-150mrx@2600...2210/1630@200yd.
Would not be much any of those would not drill through out to 200yds.

I also feel one would not have much problem getting 2700fps140mrx 7MMx54MS,(people get 2900+ in 7mm08) It would be a deceiving little devil of a performer...2340/1700@200yd. also 154IB,2550fps...2230/1700@200yd.

.308x54ms165mrx@2500+ good also...many ways to have fun.

A member who has been in and out for a while and goes by the Handle of Small Fry... he built a 30/30 on a Ruger Number one action a while back, that I was following with great interest...

either PM him or do a search on the subject.....

He did it back in 2005 I believe...

I do have an R-1 in 30-30 and it is one of my favorite rifles. It has a 22" 1-10 twist barrel with sights of my own making and it is all stainless. I can get 2400+ with a 150 but not much more... the 30-30 only holds so much and pushing it runs you into pressure fast on small cases. When I run the numbers and look at your brass... I don’t find the 30-30 to be any weaker than the next but again with a small case you just can’t expect huge gains, even in a single shot falling block.
Now I am not sure what you plan on shooting with it but TSXs do not come to mind I like to see TSXs leave at 2700+ as a min... I use pointed bullets and RNs. The 30-30 is one of those cartridges that reminds us that shot placement and penetration is what kills.
Also...you might look into the 270 savage or the 300 savage, both are fantastic cartridges... and about as efficient as cartridges get.
I picked the 30-30 because I wanted a light popular cartridge that had a rim. This gun is light and has a true 200 yard range on varmints and deer.
What do you plan on using it for?

I don't know where I read that the 30-30 was weaker than the 375 winchester but I know it came from something about the 7-30. Winchester still makes 375 winchester brass so it's no big deal to neck it down to 7-30, 30-30, or 30-30ai.Ihave both 30-30 & 7-30 contender carbine barrels & really only use the 7-30. In the summer it's loaded with 100 gr hpts & winter 139 flat bases. This combination makes a really handy light almost recoil free fun gun to have around.There is really not that much difference between 7-30 & 30-30. I have been looking at buying a Umberi low wall in 30-30 but just don't see well enough for iron sites. If I had it to do again I would have been born rich so I could have affotded fun guns when I could see & did not shake...Have a great holiday

Small Fry,


thanks for chiming in on this...

smallfry,
It would mainly be for Hogs to 200yd.
I imagined more than 2400fps-150gn from a rig like yours.
As said ,I want good mix of velocity,power,penetration,frontal area,minimal recoil package formula(7lb rig) if you know what I mean. Something between 140-7mm..150.30cal seems to come up trumps. The 150.30cal dont loose all that much to 7mm140gn out to 200yds,plus they offer that frontal area. I do prefer tougher bullets even in smaller and lower velocity rounds. I have seen some SST (139sst/280rem) pills loose alot of weight(40%+) on sheep/goat at well over 400yds, bit dissapionting. So I like the idea of an interbond,tsx/mrx even in the smallerlower velocity rounds for 200yds. they will still have the velocity for expansion, but retention for max. penetration, to get the most from the modest rounds were talking about.
Ill do more research on 3o3o, but ouside of that,7mmx54ms or 7mm/250sav,140mrx 2600+, should also do the job.
That short neck on the 300sav.bugs me! I could make a .30/250sav to get around that. Althought not as blown out as the 300sav, I dont see why I would not still get 150mrx@2600+
wj.

Let us imagine you are Olin, who makes the WW brass. You sit down with your engineers and say "I have a great idea. Let's make our 30-30 brass out of scrap so it's weaker than anything else we make. Let's have a special set up so the case design is weaker...that way we can be voted #1 by the trial lawyers assn.".

This is an old wives tale that seems to be immortal. The only thing weak about 30-30 brass is the chickensh*t lockup system on the 94 Winchester. The action is springy, so the brass stretches...so you work it twice as much as boltgun brass FL resizing it...so the case grows and has to be trimmed more often...the excess length brass comes from pulling it off the area just in front of the web...so you get incipient casehead separation sooner. 94's are notorious for excessive case expansion.
