No manual I have lists this combination, and Hodgdon's web site does not list 185 grain bullets. Does anybody have any published start and max loads? Does anybody have an actual max from their particular rifle? I've been working up from 41 grains to 43.5, no problems yet. just loaded 44.0 to 45.5 for tomorrow.

I'm looking for a load that will get the elevation right on the open sights on my vz-24 and/or Turk. I know published data is conservative, but, at my experience level, I don't want to stray too far over.

Anyone have a favorite load with H4831, IMR4350, Varget, BL-C2 or Varget?

Does any manual give data with 185 grain bullets?

Most data is with a 180gr projectile, but it gives you a guide to work from.

The above link is to the ADI website, they make most of the Hodgdon powders including H4895, Varget, H4831SC.

BJA,

When I am faced with this problem. I extrapolate the data. Max load for 195 grns is 45.8 max load for 180 grns is 48. That's a difference of 2.2. You have a difference of 15 grns of bullet wt divide the 2.2 by 15 and multiple by 5 and round down for safety and ...gets you .7 grns then take another .3 grns off safety. Therefore a guesstimate max for 185 is 46.2...I would not exceed this number.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Thanks. That ADI link is helpful. I had been extrapolating from 170g and 200g data, I'm glad your numbers are close to mine. These charges are not far from data I've seen on IMR4895, too.
