Was able use the 107s to take 3 AG/nuisance tags. They worked well. Had one rodeo due to some ranging error but I believe the wide wound channel helped in that case.

I didn’t take any pictures of wounds, was a quick one evening hunt. But the 107s worked well. Deer below had a golf ball sized exit.

Prob a little aggressive w the H4350, MRC showed no pressure, Tikka bolt was a little stiff on 1 out of 3 or so. Will back back off w a goal of 2800fps, which puts 1800fps at around 900 yards at my current location.

Looks good. 41.5 H4350 could be a touch high in charge weight in non Hornady brass as they hold less.

I received my 116s yesterday, loaded them with rl16 from 40-41.5gr to check for pressure. Im at same 2.875 oal, which is 65 off in my saami 6cm.

What is your barrel length for both rifles?

18”

Again, my point was 41.5gr H4350 is prob too much. Do what I say, not what I do

Thanks, It caught my attention because it’s was moving pretty fast. I have a test loaded up and was planning on going with 40g of h4350. What are you gonna drop down to?

I used 41.8 of H4350 with the 112 MB's, so that makes sense.

I’ll prob drop to 40gr h4350 and see where that puts me.

I’ve been happy with the results of 40 gr of H4350 at 2800 fps out of my 18 in 6 creed. I’m actually going to settle around 39.5 for now at 2750 to shoot a NRL match. The accuracy improved slightly backing off.

Thanks for the feedback! Anyone have any input with n555? I see 42ish seems common to be around?
