anyone used 1680, when the temps rise up around 90 to 100 degrees?
got some loaded up, that are fine at 60 degrees, but wondering what to expect if loaded ammo is what I have with me when the summer temps hit in the rodent fields...
load is 20 grain behind a 32 gr V Max in a 20 Practical...
getting great accuracy, and got a couple of pounds given to me in lieu of payment on a debt...
thanks in advance...
