Came across a Savage 10 FM "SIERRA" in 300 WSM, it only has a 20 inch barrel. Anyone ever try a WSM with a barrel that short? How do they shoot?
I am looking to replace my gun I leave with family back east for a week of PA whitetail / Bear season it sure beats taking a additional bag on the airline. The price is right�
.................With my Frontier, I have propelled a 150 grainer in excess of 3100 fps, a 180 in excess of 2900 fps and a 200 grainer @ 2800 fps. And I haven`t even tried Rel 17 yet! 3000 fps with a 180 grainer and from 16.5" tube using Rel 17?... Don`t bet against it!
All this hype and biz about muzzle blast and noise,,,is just that! Hype!
Those speeds are more than a bit hinky sounding to me. A 16.5" tube should run a 180 in and around 2725 fps, not 2900....
Your 7.5" shorter than what is normally used in a 300 WSM, you will lose somewhere between 25-33 fps per inch. At that much of a shorter barrel you should be running a 180 right along @ 30/06 speeds.
Something in the hen house at quite right.
I'd be for thinking that you've either the fastest 30 cal tube in the world, and or your clock in giving you hinking readings. Or you're on the all time all star red line team and should really be thinking about pushing back from the scale a bit.
But, from reading your post I think you'll just take offense to this (when you should be taking note) so never mind. Powder River let er buck and don't forget to wear your safety glasses and helmet (just like when I lost my virginity...grins).
And if you care to clue us in what is your load that will allow you to run a 180 @ 2900 in a 16.5" tube?
Many thx and best of luck to ya!

...............Dober!....A little skeptical are we now??...Ready for some fun?
Do you currently own a Ruger Frontier chambered in a 300 WSM?
If so, any chrony experience with one? Is the answer no to both by chance? Possibly?
If you feel that the hens in my hen house are a little out of order, or that my chrony is in the twilight zone or whacked out, I`ll do my best to line the hens up for you and have a word with my chrony to make sure its not sick! Kinda like getting all the ducks lined up in a row too?
Who says I should be only running at 30-06 speeds? How do you determine that? A loss of 25 to 33 fps per inch? With some rifles maybe!
First, I will refer you to please see "shootingtimes.com" then click on "long guns." Then scroll down to page 6 at the bottom and click. Then find the article entitled "Short Answer About Scout Style Rifles" by Dick Metcalf. Then go to the page 3 sub-heading within that article entitled "Short Barrel, Long Reach."
His Frontier, a 16.5" tubed test rifle in 7mm/08, propelled a 140 gr. factory bullet @ 2647 fps. That same identical 140 gr factory ammo from a 24" 7mm/08 rifle, chrony`d at 2770 fps. Well! Well! Lets do some math here! 2770-2647= a 123 fps difference, divide by the 7.5" for the barrel length difference and look what we have. 123 fps divided by 7.5" = a loss of 16.4 fps PER INCH, or an overall loss of 4.5%!...UH OH!.. Whooops! That`s from Dick Metcalf! He also says that ALL calibers chambered in the Frontier, will or should have similiar results!
Let`s go further shall we. Please go to "reloadersnest.com," then hit "rifles" then scroll down and find 300 WSM. There you`ll see a bunch of reloads, which can be duplicated..... And with some,,,I did exactly that!!
First, please find 150 gr. and click. Find load # 7544. From a 24" barreled 300 WSM, using 65.5 gr. W/760, what`s his velocity? I read 3255 fps. That exact same load in my Frontier chrony`d at 3118 fps on average. 3255-3118= 137 fps difference divided by the 7.5" of shorter barrel length = 18.26 fps per inch! Or an overall velocity loss of 4.21% when you do the math....How about another?.....This is fun!
Second! Please find 180 gr. and click. Find load # 10475. From that 24" barreled 300 WSM, using 69 gr. Rel 19, what velocity do you read? I read 3050 fps. That exact same load chrony`d 2917 fps on average from my Frontier. Let`s do the math again; 3050-2917=133 fps divide by 7.5" which = 17.73 fps per inch, or an overall velocity loss of 4.37%......Getting interesting for ya now? How about one more time shall we!
Third! Please find 200 gr, then find load # 10476. From this 24" barrel, I read 2930 fps using 68 gr of Rel 19. I chrony`d that exact load at 2811 fps on average. 2930-2811= 119 fps divide by 7.5" = 15.86 fps per inch or an overall loss of 4.07%.....
How are the hens in my hen house doing now?? Still a bit hinky??
BTW! We had a second back up chrony to verify the first!!....UH OH!.....Whooops again!
When you take all three loads and their percentages of loss and average them out, you come up with an overall loss in velocity of 4.216% from the loads that I duplicated. Metcalf`s percentage loss was what in that article?......4.5%!!!!!!!
Hey! Maybe those other 24" 300 WSMs were fast barrels too?? Right?
25 to 33 fps per inch? Well! Not in my case sir! In the examples above, if you calculate what,, as you say,, should be the loss from 25 to 33 fps per inch from their velocities given, you`d come up with an overall velocity loss of between 187.5 fps to 247.5 fps. That calculates to 5.75% to a possible 7.59% of overall loss for the 150 gr. A 6.14% to a possible 8.10% of overall loss for the 180 gr and 6.39% to a possible 8.44% of overall loss for the 200 grainer......Those percentages are TOTALLY IN-CONSISTENT with Metcalf`s chrony findings and mine as well. In fact, my findings are far more consistent and extremely closer with his vs your estimations.
Many have a tendancy to under-estimate the performance from the shorter barrels. I cannot speak for other cartridges, (except my 375 Ruger Alaskan`s ballistics from its 20" tube), but when it comes to the 300 WSM, its performance from the shorter tube, is outstanding! A great shorter barreled round in a handy 35.5" compact rifle, which BTW has some reeeeel good long range capability,,,wouldn`t you say?
BTW! They all grouped,,,,quite well!
Don`t worry. I didn`t take any offense. However! It`s just alot of fun presenting the facts!........Any questions?
And! Good luck to you too!
