106 TAP for hunting?

[sportsmans challenge]

I’ll load some in the 6 UM. They shoot like ELD-M’s, though mine aren’t seconds.

Appreciate it, I feel honored to have the premiums shot for some nothing super important data. N570? I know beggers can't be choosers

Well, sure. It was yours.

This is sorted by ogive length.

If a couple of you guys could get these to shoot tighter with faster twist I am going to order up a couple new barrels.

Hornady app shows 7.5 twist as marginal at low temps and near sea level. Even though they are a 106 these babies are LONNNG.

Will load some up in a 7.5 twist 240 Wby tonight and hope to put a few down range in the morning using a 108 ELDM load I’m dialing in. It won‘t be 16 degrees like yesterday morning in NW Florida but expect it will be in the 40’s.

I’m still deer hunting in lower Alabama until 10 Feb, if the 106’s shoot ~ 1.5 MOA I’ll see if I can put one in a Whitetail.

I think 7.5tw is a good bet on any non magnum 6mm if you plan to shoot heavier than 105gr bullets.

I have a pile of these 106's, planning on a 6prc and a new 6cm barrel

When loaded to the same BTO as my 105s in a 243, they won’t fit in a factory Tikka mag but the 105s do. Definitely long

What B.C. do you plan on using for these? I thought I saw .580 somewhere.

Ab has .281g7 .548g1

 

[Chanimal]

My order came with a .264" something extra.

 

[Wrench]

I have a muller and bart 7tw in the mail.....but time is killing me from spinning them up.

 

[280Ackley]

Would a 1:9 twist 243 stabilize these?

Would a 1:9 twist 243 stabilize these?

Doesn’t look like it at this point but could be dependent on how high in elevation you are possibly.

Hornady recommends 7.5

 

[sportsmans challenge]

Hornady recommends 7.5

Will see how an 8 does, but with more velocity

Does anyone have in hand:
-Berger 105/108/115
-Hornady 103/108
-Sierra 95/100
?

If so, could some take a measurement from the back of the bearing surface where it meets the boat tail to the ogive?


I have a bunch of these 106mysterys and will have my throat cut from a dummy round that has as short of a jump as possible. I may hunt with any of the above bullets, and I think I'd likely seat that dummy round like I do all my cartridges with the bearing surface/boattail junction at the base bottom of the car neck.

If I understand which of the above bullets has the longest measurement, I can know it's a no-go or plan in advance. I do understand that your measurement will be less than precise, but it gives me an idea without buying a full bow of each sku.

I have Berger 108 Target. I'm assuming you want the hunters. If you want measurements from the 108 target let me know and I will measure and post.

Berger has specs on their site. If you are able to grab a measurement for what you have, I can compare it to mathing out from their listed specs for the bullet you have. I think if those numbers match, I can math out for the other Bergers and be comfortable assuming they are correct for my purposes.

So, yes please!

I made 3 dummy rounds of 6/284. I eyeball seated bullets with the boattail at the shoulder junction. My measurements were:
106 mystery - 2.402
108 eldm - 2.433
115 dtac - 2.472
I know it's not real precise but close enough that I sent the 106 dummy round to the GS chambering my barrel.

Sweet! Thank you.

When you ask for chambering, what jump do you like it to be cut at?

My assumption is if I have it cut close, as the lands erode I am still at a reasonable distance and might get a scooshyscosh more usable time with that barrel before it is done.

I haven't specified a jump measurement. I'm open to and encourage suggestions from anyone knowledgeable. The barrel and dummy round are in the mail. Is jump a consideration for a person who doesn't clean barrels anymore? Does chasing lands extend usable barrel life?
