What was your best powder weight for Varget for both rounds? I may use your optimum weight to focus my loads around.

Nice job Joe! Give some 40gr and 50gr V-Max bullets a try! I shoot .5" groups from My Bushmaster Varminter all the time with Hornady Vmax 40gr. It puts Ghogs DOWN in a hurry!

Ill have to try them. I had to take my rifle to my gun shop where I got the Timney I was at the range last weekend and it started double firing Shooting

they give you instructions if this happens but I had a slow day yesterday and took to the shop and he adjusted it I will shoot it this weekend hopfully.

That can happen with the aftermarket triggers at times. Mostly because they are adjusted lightly and get dirt/residue from the chamber gets in them. It is a gas gun after all, The piston conversion can stop this from happening, but thats
an expensive fix. get the darn trigger readjusted and loctite the screws. Cheap, and affective. just dont use the permanent loctite. Very Happy

Thats what I did on one of my AR with a JARD trigger.

We adjusted the disconecter I will find out this weekend if it fixed it Laughing

Went and shot it today Very Happy

It worked great. I also just ordered some Nosler 69 grain BTHP's and a box of 70 grain TSX's Very Happy

we will see how they shoot

Glad the fix worked AOK! Interested in how the 70gr TSXs do. My 16" AR with 1:9 likes the 69gr SierraMK.

I will let ya no Very Happy

the sierra game kings 65 grain are shooting 3/4" groups with both Benchmark and varget I'm hoping to get a little better with the Nosler BTHP's

Went and shot some Nosler 69grn HPBT's and 70grn TSX's. I tried some H4895 as well . Best groups so far were 69 grn nosler-25.5 grains of H4895 was 0.704"... 25.5 grains of Varget was 0.658"...... 70 grain TSX. 23 grains H4895 was 1.082" and 24 grains of Varget was 1.040". I'll keep workin on them Very Happy

I may try some benchmark also

Those are both good starting loads and surely good enough to hunt with (was that a typo on the Varget load). Looks like you are close to max load. I'd be interested in what velocities you are getting.

This is the one I got and I'm very pleased with it. I also got the cable that attaches to my laptop so I have digitial records.

ProChrono Digital Chronograph
