Does anyone have a good load for the sierra 175 gr match king with 4895 IMR
- Thread starter gunfreak101
- Start date
41.5 in LC brass has been accurate for me.
42.8gr IMR 4895 2650 fps 21" Bartlien 5R Win brass
I use 45.0 Lapua Brass CCI 200 primers.
I don't have a chronograph but book says 2,704 FPS?
Per the ballistics calculator with that speed it tells me to dial up 11.8 Mils at a 1,000 yards which is wrong.
My dope at 1,000 is 9.4 Mils.
I must be faster than the book says?
24" stock HS Savage.
PSE EVO 60 Lbs.
Blacked out

Deer, I would think that load is close to 2800+ FPS.
I run 42.5 Gr of 4895 in a Winchester case. I get 2530 FPS out of an 18.5" Hart barrel. I think I could go a little warmer, tho. J
I'd think that anything over 43gr IMR-4895 with a 175 would be very hot but there might be some rifles it would be safe in. 45gr would be in the zone of please don't shoot beside me.
I shoot 42.5 with the 168's and get warm results with them at 43.0 and above. This has been common thru several rifles with that powder.

I use 43 grains with federal match brass, federal match primers, I get 2700 fps with my HS precision 24" barrel.

Try 42.5. I've shot thousands of these.

I plan on using the same bullet and powder for my LAR-8. Any recommendations for an AR?
41.5 in LC brass is an accuracy load for M1As w/ 168. You should be safe around there with the 175.
42.5 under a 168 SMK is pretty mild in the 2 rifles I've used that combo in; book data goes up to 45.4 gr and I've run it all the way up there.
Neither has a very tight chamber (shallow throat) though.
To the OP, you're going to have to run a ladder or OCW to find what works in your rifle.
A good load in another rifle may not shoot worth a $hit in yours.
I'm running 43.5 gr I4895 under a 168 SMK in my AAC-SD.
Just got my 175s so I haven't spent any time developing for them yet.

The DuPont M118LR load, which seems to have been a better load than the current one (ATK, RL15 driven), used 42.0 grains of IMR 4895 in LC match brass with the 175 at 2.800" OAL.
