Question on primers.

[GreggB]

TC Omega using 2 pyrodex pellets with a Barnes 250 gr Spitfire TEZ. Next week will be very cold with single digit temps. Considering switching from Muzzleloader designed primers to 209 shotgun primers for better ignition. Just wondered if POI will change much on shot under 100 yards. The rifle is zeroed at 100 yards.
