I have a 16inch barrel 30/06 Columbian Mauser (carbine). I've been meaning to take it hunting but have too many other firearms in preference. I've also been meaning to find out what velocity I get out of it. Accuracy is acceptable considering it is standard ex-mil configuration with the horrible spire front sight and V rear - my aging eyes have trouble with those. Do you have access to Federal Power-Shok 180gr ammo (blue box stuff)? If so I'm getting a 5 shot average of 2509fps at the muzzle from my 17 1/2"bbl for you to compare to. That's not bad - I've got a max. listed of just under 2800fps for a 180gn in a 24inch barrel (from ADI reloading data). I think I gotta buy a chronograph now - too many unanswered questions starting to pile up.
Whatever you said...everyone knows you are a lying jerk. That's a bold assertion. Point out where you think I lied. Well?

I've used a 20" Ruger 77 Ultralight in .308. Mean kicking little devil. What ranges do you have out of your box blinds? Woods, food plots, bean fields? Hard to beat a leveraction 30-30 for close shots and handy. This.

Oops I missed your earlier posts on chrono data. Those are pretty healthy velocities. I'll bet you get singed eyebrows though. ........LOL.......Not in the least. No singed eyebrows......Muzzle blast not as bad as many think..... Many from the get go under estimate the MVs that can be had from the shorter barrels. Todays modern powders close the gap.You are right, and that is especially true when using heavy for caliber bullets. With light bullets, short barrels are often down on velocity just as much as people expect, but heavy bullet speeds can be a lot closer to what long barrels do than most expect. With short 308 barrels for example, I've found that 175gr bullets are often not too far behind 150gr, while there is a considerable gap between the same loads in longer barrels.

I went out and bought a chrono and could only get the 150gn Federal Power-Shok ammo. I think it might be loaded a bit light because it wasn't all that loud and most primers were backed out a little bit. 2600fps was the average, so that's equivalent to 300 Savage velocities, and down from the 2900fps on the Federal website (22 or 24 inch barrel?). I'll look for the Federal 180gns but will try my reloads (much noisier) and maybe also Winchester 150gn factories, for some sort of comparison.

With my handloads using 150gr Nosler Solid Base bullets,56gr IMR4350,Federal casings,and CCI250 primers I'm getting 2545fps from a 5 shot average. Judging from numerous references I'm guessing it would get 2800fps or so out of a 24"bbl.

I just realised that those loads are still equivalent to what a 303 will do will a "normal" barrel. I think I use 62gns AR2209 (equiv to IMR4350) behind a 150gn - I'll have to check, and crono.

I've never had any deer complain that the load doesn't work. lol
I've been downloading cup and core bullets for a long time. I'm just not at all fond of processing a bloodshot excessively damaged animal. I even run my .270 Win 130's at 2763fps.

I tell a lie, my loads are:
144gn FMJ, 61gn AR2209 150gn spitzer or 155gn PALMA, 60gn AR2209
My reloading spreadsheet says I've got some of the 144gn FMJ's loaded up in the cupboard at home - I guess these will be coming out to the range this weekend.
They'll probably be doing around 2600fps too I suspect. I think AR2209 is too slow for the short barrels - I use it mainly because of the impressive boom and flash that it makes. I have AR2208 loads that shoot as well (50gn) but don't flash as much. I like spectators to enjoy the short barrel as much as I do. AR2208 is sold as Varget in the USA.

Tried some Winchester factory 150gn Super-X - same velocity as the Federal factories: 2600 fps.
My 144gn FMJ reloads did 2625 fps average, but with the added boom and flash. I had the crono about 2 m (6 ft) in front of the muzzle but it got knocked about a bit from the blast, and the first 2 readings were in the order of 6400 fps! I shifted it out to 3 m (9 ft) and it worked alright there.

Move it out to 15' and just add 10fps to the reading. Close enough for government work and no worrying about muzzle blast.
Those velocities are good to go. I had thought about bumping my 150gr load (2545fps) up to around 2700fps but there's no real field advantage ballistically or trajectory wise.

Brought my newest 20" 308 out today and shot the same load that I shoot in another 20" and got sub moa with it. Same drop at 250 yards so the velocity is very close. This was the first time I shot it since cutting it down from 24" . I really like having 2 guns that shoot the same load , one is blue with wood ( blue bird weather gun) and the other SS and synthetic.
