Quick Load for the 6mm Remington

[Aussie Wanderer]

Sorry to impose a second time. I was also testing the 6mm Rem with 70 grain Nosler BT's just to mix it up. I was running Varget which seemed to give me better groups than the H4895 I originally started with. The rifle is a Remington VLS with a 26 inch barrel. I have tidy group at 42 grains and two pretty reasonable ones at 43.5 and 44.5 grains. Again if someone could give me an idea on velocity and pressure that would be great.

This has always been a solid rifle and that little 6mm Rem is such a great little round. I was using 95 Grain NBT's over 48 grains of RL22.

Thanks again

Nice shooting. Those 700 VLS rifles are shooters.

It has been a great rifle. Boringly accurate if there is a such a thing. But also a really good rifle to experiment with because you know what it is capable of. Also kinda cool because the old 6mm Rem doesn’t get much press or love these days despite it being a really capable little round.

Thanks Dr Mike, I think I have confused the issue and hope I haven't been a pain. I couldn't get the H4895 to shoot but did with the Varget. The loads of 42 and 43.5 that showed promise was with Varget. Could I please indulge on you for this as well. I should have been more clear.

Interestingly when I tried H4895 the best it would do was just over an inch. Varget or 2208 as we know it here tightened the groups up instantly.

 

[Aussie Wanderer]

My guess is that the 42 grains of Varget will be running somewhere around 3,500 fps.

[Aussie Wanderer]

That is fantastic, thank you very much. I think 3,500fps with good accuracy is plenty. Chasing another 100fps or thereabouts and groups opening up isn't worth it.

Much appreciated Dr Mike

 

[Aussie Wanderer]

So the 70gr NBT was running at 3,511fps with 42 grains of Varget and the 95 Lapua HPBT's were running at 3,227fps behind 48 grains of RL22. The 95 is truly sweet load regularly shooting under 0.5moa. Hope that info might help someone out as well.
