I'm thinking of building a pair of rifles based on the bumblebee/vampire actions....but I tend to shoot a lot. I don't make a habit of babying my gear and these will see nearly all their time in the field or riding on the passenger seat blasting wheat fields chasing yotes.
I'm curious how the...
This is for antelope? Not sure why you would limit yourself to these marginal performers and leave the chey-tac and snipe tac lines off the table. Antelope can take a beating with their massive bodies and thick skin.
There is also the "feels good" and mark method that works well.
Think about what you are doing. If you have a narrow cap with 48tpi screws, you are going to need to be more careful than a wide cap with 32tpi screws.
Snug it up to contact, square it up and mark it with a sharpie or...
I don't have the sig or any m&p pistols....but I have every other one written about and I have killed a big bear with a 10mm at face to face.
I carry a 43x with berry's hybrid 147's or a g23 with 180xtp's.
I fully intended to do a 6x284....but after seeing the results from this last xc I spun up, the juice wasn't worth the squeeze. The xc gets 3100 with that long 106 tap and shoots it VERY well. I can't give up 1k shots of barrel life and eat the extra 10-15 grs for another 1-200fps.
Yesterday I...
Here's some easy to read info on how quickly pitch can affect clamp force and bolt stretch. Pay attention to the finer pitches and how quickly clamp force comes up with little torque input change. Look at how small the wet vs dry coefficient is....and then note how substantial a clamp force...
I mostly believe this is the issue as well. There could be some squareness issues between the counterbore and the mate surface or the rings could be out of square. This is one time where alignment dowels before it was torn down would answer a lot....like who's at fault.
.....But there's so...
I'll happily argue this.
Grab any edition of machinery handbook and find that there is in fact a difference in torque for wet vs dry and that everything has a coefficient of drag. The percentage reduction is directly related to pitch. A 48tpi IS going to stretch more than a 13tpi...
