22-6mm Extended-Long Range Groundhog

I am looking to build a 22-6mm after speaking with Lonnie Hummel at length, he mentioned 39-4100 with 55 Vmax and 36-3700 with 75-80Amaxs. I plan to shoot the light stuff out of my factory XR-100 single shot 1:14T barrel until Bartlein has my 1:8.5 30" 5R barrel finished. Then i will move to the 75 and 80Amaxs.

My targets will be slow fire and western PA groundhogs at out to 800yds or so. According to Lonnie he has shot over 2000 rounds through his barrel and only retouched the throated and crown once.

What are you guys seeing as actual real world experience? I am ready to order my reamer today and i was advised to check here for opinions and first hand experciences first. Good, bad, ugly.....lay it on me!
Thanks guys

Re: 22-6mm Extended-Long Range Groundhog

I don't have any personal experience with it, but I've seen some guys shooting it. Actually, I've got a question for you.

Is this a short or long action? I think I'd want one on a long action for the heavier bullets, but I cant say for fact that a long action is absolutely necessary.?

Re: 22-6mm Extended-Long Range Groundhog

If your intended targets, groundhogs and paper, are 800 or so, why the .22 cal?
I shoot plenty of PA groundhogs at long range and extreme long range. For the 800 yard stuff, I would make it simple and shoot one of the many offerings in 6mm. the 105-107 grain bullets will fare better than the lighter .22 cal stuff even if you push them faster than the 6mm.
You'll have a tough go with the .22 when the wind is stiff..but hey, it may force you read conditions better..

Re: 22-6mm Extended-Long Range Groundhog

Run the numbers 22-6 3600fps 80amax .453 Published BC. 149" of drop at 1k yards and minimal drift.

I am using a short action an I know to remove a chambered loaded round I will have to remove the bolt, not a big deal to me.

Just looking for real information not "there are better choices IMO".

I did run the numbers, and they support the information in my original post.
The numbers also calculate to 190" drop at 1,000, not 149".
Taking your numbers, and comparing the data against one of my 6mm's, you fall short on drift at 1,000 by 1.25 moa.
500 yards and under your .22 cal will be fine. Stretch that out to 800-1000 yards, and your .22 cal will fall short on drift.

Also consider that barrel life on a .22-6 something will be significantly shorter, and that the .22-6 something will certainly be more difficult to develop an accurate load for.

Take a look at the line on any 600 or 1,000 yd match and count how many .22 cal comp rifles you see. There's a reason for that.

That is your "real information", and in my opinion, one of the 6mm's is a better choice for your intended purpose...

My buddy, geargrinder, has laying around a barrel chambered in 22-243 Improved and I thought about having him installing it to my savage action... The above reasons kept me from doing it. Exactly right!

There are indeed better choices.
