Range Report Whats your velocity for 175smks?

Re: Whats your velocity for 175smks?

24" Savage
175 SMK
Lapua Brass
Fed 210
43.5 Varget
2680 FPS

I have no idea how I get that speed. I wouldn't believe my chrono but Ballistic FTE puts me dead on at 600 for that speed.

Re: Whats your velocity for 175smks?

I run 44 grns of Varget and I get 2725-2790 fps depending on the time of year. My barrel however is a 25" Krieger. In my experience custom barrels tend to be slightly higher on the velocity side that factory ones.

Re: Whats your velocity for 175smks?

Thanks for the replies, I am using win brass.

I should add, that I havent chronod this load. I shot at a bunch of varying distances, recorded my dope, then plugged a velocity into a ballistics program, and worked it backwards 2605 is what I got, that matches my trajectory.

Is this wrong? I figured it would be fine, being as they match each other, but could my velocity still be different? This has been fine to 750yds (farthest I have driven it out too).

Savage 10FP 26" pipe
45.4 gr. of RE15 2678fps @ 17 deg. C

Hit the wall at 45.4, went on to 46.0 gr. of RE15 in .2 increments with virtually no increase in velocity.

Your over 1k ft higher than me, when I did this it was in the 40s I think. With around 50% humidity and my dens alt hovers around 1550, normally.

Thanks, glad to know I'm in the ballpark. Will u stay supersonic to 1k?

Sounds find to me. Every rifle is different. The strange part of my load development with varget and the 175gr BT LR is, that i never got a huge jump in velocity even at 45gr. At 43.5gr only 3 shots chronoed, got errors on 2. But i got 2602, 2602, and 2597. Then 44 2617,2618,2613,2623, and 2624. Increase on assumption per .5grains seemed around 20-50fps. When i got to 44.5 it was around 2635-2640. And at 45 only hit 2700 once most were around 2680. I was expecting more of a jump i guess. I know varget is very stable as far as temperature goes but i imagine environmentals will add a bit of a differenc also.

For where i am, right now in the summer with the humidity and temp being high everyday estimations from JBM is reading 1255fps @ 1000yds. When i first started this load in early winter going on spring i was getting estimations around 1206fps @ 1000yds.

About two months ago I decided to find out what 6" of barrel length would yield with identical loads fired in both of my Remington’s, one 20" tactical and one 26" varmint. Here is what I found, FWIW...

Remington SPS Tatical20"
175smk 44.5 varget load @ 2.825oal = 2550fps
155 lapua scenar varget 46.7 load @ 2.825 = 2750fps

Remington Varmint 26" same loads as above.
175 = 2645
155 = 2850

So in these two factory rifles you gain ~100 fps from those extra 6" of factory barrel. I also have a 21" rock creek custom that matches the 26" factory barrel velocities so it does make a difference on what you are comparing.

To slow, as compared to what others are getting with the close to the same load, but apparently I am in the ball park.

Re: Whats your velocity for 175smks?

Your velocity seems a little slow. I'm using exactly the same gun.

Federal Brass
Winchester large rifle primer
43.0 grains of Varget
175 SMK
Velocity 2626 fps from a Pact mark 4 chronograph/timer.

Ran out of 175 SMK's before I got to 44 grains.

What is your da, temp, and humidity, just curious.

correction,sorry guys checked my loading book and im actually runnin 42.5 grains of imr4064 to get that velocity. real temp stable tho.

Re: Whats your velocity for 175smks?

Not chrony my handloads yet until I shoot all my factory ammo, but with a 22" GAP ROCK, getting 2695 for 4 shots of match 175smks...

Dont think the vel really matters esp if you found a real accurate node...anywhere in the 2600's would be acceptable to me.

AI-AW 24" 1:12
Black Hills brass
43.5 Varget
F210M
2.810" COAL
2630 @ 800' ASL 90F

The barrel can run faster, but this is a very nice accuracy node.

Same load runs 2700 fps in a 25" Krieger 1:11 chambered by Mike Lau.

Winchester brass
.015 off the lands
2776 fps average of ten rounds at 81 degrees at 11 feet
.5-.75 moa (but I'll be working on the action screws a bit this weekend, hopefully tighten that up), and best part is over a grain under max, nothing even close to a pressure sign!

Re: Whats your velocity for 175smks?

Some great information in here! I am not a handloader so the only relevant info I have is SW's 175smk, thru a factory Savage 1:12 30" barrel and cheapo $70 wally world chrono...average 2770fps. I have no idea what their load specs are.
In hindsight I wish I would have had a chance to shoot them at longer yardages and back calculate the fps.

This. I too run a 25" barrel, but mine is a Bartlein 5R (match barrel). I load 44.4gr Varget under 175gr SMK in Lapua brass with CCI BR2 primer, seated to 2.820". I manage between 2720fps when cold, to 2770 fps when warm.

That sounds too slow. I use 175g SMK over 44.0g of IMR 4064. In my Rem 700 LTR w/ 20" bbl I average 2670 fps MV. That's been verified on two different chronys (different brands).
