22GT .120FB vs .169

[JoeK]

Considering the 22GT for cup’n core bullets in the 75-88gr range and also interested in trying some of the 70+gr monos from Maker, lehigh, hammer for open country deer/pronghorn hunting.

If anyone has experience with the 22GT which chamber would you choose? .120 FB or .169?
My hunch is that I don’t actually need the longer FB but according to the interweb monos may prefer longer jump and I don’t know how long I would want to seat the 80-88gr either…

I had the .169 freebore and it shot the 68gr HHTs fabulously.

I have a 22 creedmoor with 120 and my buddy has the 169. I loose case capacity with the monos. As soon as he brings me his rifle so I can make a dummy round for the smith I'm going to have it throated to 150 I think thats the sweetest spot.

In my experience, too short is a problem if you have to seat bullets into the case losing efficiency and getting donut problems. That is the determining factor for me. Will the longest bullet I want to shoot fit?

I haven’t measured the lands in forever.

While throat length may be something bench rest guys say they can see effects (Eric Cortina says he doesn’t chase lands) I haven’t seen that it matters in a practical sense. I think half of what they do is like the religious ceremonies the bladesmiths used for samurai swords. Some was metallurgical and some was ceremony. Hard to say which is which for lots of shooting “rules”.

I stopped worrying about jump a long time ago.

There are manufacturers who are known to have long throated rifles and they still shoot.

I think if people believe it matters, then it does to them. But, if you want to know whether to believe it or not, don’t choose that fork in this moment in time your life.

If you might shoot monos, pick the one that the masses say works and be done with any more energy into the thought.

That is my opinion worth everything you paid for it.
