My rifle stock (Sako TRG) is not a good friend with a rear bags. Then, I asked myself a question. How much does it really matter. I have no doubt on 100m. Precision is always better with a rear bag. But, what about further, does it really matter. WEZ is telling me, no it does not, better focus on ballistics and wind management.
So, I tried. I have very small light Caldwell rear bag. For which I made shimmed foam fundation to be able to adjust hight.
Then I stopped placing my rifle stock in it. Instead, I start to use it as a support for my hand. In a beggining I used fist, but later I switched tu thumb only. The bag is inside the fist and rifle stock is on a thumb.
And then I practiced that for some time to achieve consistency.
And yes, I lost some 100m precision. But from 300m and more, I see no difference. I am well capable to shoot identical f-class score without rifle stock in a rear bag, just like the one with a hi-tech rear bag.
I do not bother with rear bags anymore, except for 100m group shooting.
For the rest, it is used only as a support for a hand. And it is very small and very light, working in a same way from any surface and shooting position.
