Sierra 85HPBT 6mm QL Request

[George Foster]

I was wondering if I could QL data for the following:

6mm Rem
85HPBT Sierra
24" Barrel
Fed 210M Primer
Rem Brass
2.825OAL
RL19 and IMR4831

Thank You in advance.

I have no idea about Quick Load. I do shoot a 6mm Rem with Rem case, Rem primer LR, Sierra 85gr HPBT, & Reloader 19. I will also say I'm shooting groups at 300 yds that average under 2.2 inches for 3 shot groups.
My Son used above load to shoot a Antelope at around 400 yds & on broadside shot had complete pentration & DRT like it was struck by lighting.
In the 6mm Rem I also love Hornadys 100 BTSP with it and Sierra's 85 BTSP I have shot groups as small as 7/8 inch at 300 yds, but both loads average under 2.2 inches at 300 yds.
Rifle Remngton 700 BDL Scope Weaver Steel tube 3x9 40mm from the 1970's. Good Hunting.

My Q/l is at home. However in my 6mm rem this is what I used.

46 gr IMR 4350. 3390 fps and .7" group at 100 yards.

Let me know if those help you out..

As you can see QL does NOT match Hodgdon data.

If you could post your actual case capacity in Grains of H20 of a fired case that may help bring these two closer together.
