Free: Contests & Raffles.
I've been running the Vortex Crossfire on my SXP for the last 2 years and I love it. I have found the adjustment easier with gloves because I just have to adjust a dial. Also if I'm shooting a stubborn bird at 40 yards based on patterning he is getting all of my BB's. I run 7 shot Federal TSS.
Here is a blog that might help with it...and if you look at previous blogs on the same website there is another one that also talks about setting up a shotgun and red dot sight for turkey...Gradelink to blog: http://www.theoutdoorline.com/blog/post/2020/05/17/410-for-turkey-yes.aspx
I bought a Holosun based on a post on this thread. https://hunting-washington.com/smf/index.php/topic,240843.0.htmlWorks exactly as described on paper, haven't hunted with it yet.
my only recommendation would be to get a hand on what you are considering. red dot is a red dot (for a shotgun application) . some of the cheaper versions have a mirror like lens on leading glass and it (IMO) is no Bueno for turkeys and sun glimpse reflections.. i run a vortex and do just fine... Trij are 2X cost and not necessary . i sighted in at 15yds with 7.5 bird shot... holds direct at 40yds with turkey loads.. deadly! with tss if you are going to stretch it out, remember gravity drops your shot down enough to miss low.
I have a red dot but I like the simplicity of a fiber bead. Gives you plenty of light during turkey hours.
I started using a Burris FastFire 3 this year, 3 MOA, and really like it. Haven't had it super long to tell you how it lasted but I know plenty of guys that have had them for years and haven't heard of any trouble minus changing a battery occasionally, although, keep a spare with you. I can imagine it is a sickening feeling to be near a bird, turn on the red dot and get nothing because the battery is dead...
I love the Nikon Turkey Pro scopes!!
