H4895 under 175SMK .308 info

[Blowby]

Anyone have any data? I'm running low on Varget and have some H4895 which is easier to find and looking for higher MV if possible.

Anyone with Quickload?
20" Barrel, 10.25 twist
Lapua 2.010
2.865 OAL
SMK 175, length 1.245, G7 .243
Fed 210 primers


Now running 44.9 Varget pushing 2640 at 6000DA / 85 deg.

40 ( ~2480) - 42.7 ( ~ 2650) 2.800 OAL

IF you went with 8208XBR
@ 42.5 - 42.8ish you'd be pushing them 2665 - 2700 ish

I was going to use this 748 pull down and suggested to me to try the XBR. Not as temp sensitive as 748. it's a short stick, meters very well and in my 700 20" 1:12 i am meeting or exceeding accuracy with Hornady 168 BTHP-M , compared to factory Hornady 168.

Drop by and i'll give you some to try out.

Thanks Jim, might head out to Pawnee SC to test. Just wanted some first hand expierence on these.

I have 8208XBR, IMR4895, IMR4064 and H4895

IMR 4046 I use 42.1 and a Barnes or Hornady 175. I get 2640 out of my 24" Savage. It's a safe loading.

I've seen exceptional velocity from people using H4895. Work up your load obviously.

2000MR is very good for the heavies as well.

Loaded up on the hotter end of the scale since I only have a 20" Barrel. OCW to find a node first. Now I need a magnetospeed to check ES/SD.

Ran my new loads with a magnetospeed and gained 100+ in MV. Primer shows a little pressure. Used the same configuration except the primer was a Fed210M instead of just the 210.

North Spring range UT, 30 deg, 30 mph wind from 9:00
600 yard steel was my target.

Shot 10 rounds of the Varget load - 2,610 average.
H4895 in .3gr increments were 2,694, 2,712 and 2,725

42 grains of 4895 is the classic 308 load for the 175's (some people use it for 168's and 180's also)

Bison Tactical in Boulder had Varget last week.

Frederick is a good guy to deal with.

I have a new batch to whittle down to the final load, .1 increments to shoot at 200 yards, then group at 100 then out to distance. Pawnee SC this weekend. If it turns out to be my go to formula I will have some Varget to trade >>> H4895.
Just need some range time. Anyone going out anytime soon?
