Can I get SAUM help

[coyboi69]

Just built this 7 saum on a tikka action 20” proof I have several two loads I developed 165 gamechargers and 162 eldm at velocities around 2790s that shoot bugholes at 100 yards but I cannot get it to group @600 and out on several range trips and I know it’s not me I shoot a lot out to 800yrds. Any ideas where to start? already checked torque on scope and action screws. I have about 200 rounds on the barrel

When you say “bugholes at 100 yards”, what does that mean? Cloverleaf 3-shot groups, or true 1-hole groups of 5-10 shots?

5 shot groups .47 inches with 165 tgk and .64 with the 162 eldm. ADG brass 63 grains of h1000 fed 215m with and aol of 2.945

Do load development at 600 yards. Not everything that shoots good at 100 will shoot at distance.

Good place to start might be different seating depths. I would try same load but jump them in .050 increments.

I personally didn't have great luck with 162s in my SAUM. 180 Hybrids and Elds ended up performing notably better.

How bad are your groups at 600?

I have found H1000 a bit touchy in my 7 SAUM- gets some spikes with minimal powder changes and possibly carbon ring if that’s a thing?

I found H4831 more consistent and easier to get good groups with the 162 eldm. That’s what I load

10 shot groups are better for initial load dev
