    More rounds down range.

    Tried some N140 under 155TMKs, not bad but the 4064 was/is better so far.

    Ran some of the 155's at different seating depths w/4064 for some 3 shot groups. The best ones came from 45.3gr with a .4" and .65", and a composite group of .65".

    45.1 netted a best 2 of .5" and .75" for a composite of 1.3".

    168 TMKs also turned in some good groups with 4064 with the best 2 at .45" and .5" for a composite group of 1.0"

    All cycled well with no obvious pressure signs.

    I shot all of the test loads at 3 different seating depths. And not a single one shot well at the deepest seating so I removed that one group from each test.

    One variable we don't mess with is seating depth. Mark loads to max mag fed length and we roll with that. I know its a thing, just not a thing for us. And has never been an issue getting sub Moa performance. Same for Bolt guns.

    That's what I usually do, but everything I shot turned on a better group with a 2.815 oal

    The groups weren't as good today. The 168s were definitely the winner, but the 155s with 45.2 gr of 4064 were moving @2730fps. That gets them to 1,000 yards supersonic (168 were around 2600).

    I shot some more of my 168 and 155 TMK loads suppressed and there where no issues. The chrono says the was no increase in velocity. It looks like the 168s have the better performance at distance and most groups at 100yrds are 0.5-1.0".

    I think the 155s may have a slight accuracy edge, but my Remington 700 hates them and they cost more than the 168s.

    I think it's time to load up a batch and stretch out the range.

    Well done, 168's will serve you well inside a 1,000 yards. Got yourself a plan.
