Burris Ballistic Plex

[Tyler Kemp]

Does anyone know the reticle subtensions in MOA? I am interested in using one for my 45-70, but I can't find out the subtensions in MOA to compare to my data.

 

[Tyler Kemp]

Nevermind, just did some math to find MOA.

BTW, a 300 grain JHP @ 2200 fps sighted in at 200 yards=
first tic-225 yards
second tic-275 yards
third tic-310-315 yards
top of duplex point-360 yards

350 round nose @ 2000 fps sighted in at 200 yards=
first tic-225 yards
second tic-260 yards
third tic-290 yards
top of duplex point-335 yards

I wish the 325 LE bullets would become available, using 2200 fps again=

first tic-235 yards
second tic-280 yards
third tic-330 yards
top of duplex reticle-375 yards

Does this help any?

That's where I "transposed" to MOA, just wanted the easy way without changing inches @ 100 to MOA.

But it's just multiplying by 1.05 so it's not a big deal.

1.0472" to be exact.....

Didn't figure I could hold within 28 thousandths of an inch. Although for the Allen Mag shooters with their fancy Nightforce's, it might be best to calculate exactly.

 

[sscoyote]

Tyler u should be dividing by 1.05.

 

[Tyler Kemp]

Whoops. Time to recalculate.

What rifle is this on?

2200 fps is smoking for that caliber. Or at least for me, I am lucky if I see 1600 out of my 16" contender.

It is a diff. ballgame with the hotter Marlin loads & they can't be shot in a Contender!!!

I get 2,400 with the 300NP in my XLR.

This thread is sorta going sideways

52 gr. imr 4198.350 gr. hornady rn 2167 fps out of a 20 inch ruger #1 chronoed last week.This load is right out of hodgdons website,H4198 is supposed do even better.These are not levergun or trapdoor loads.Should be able to get 2500 fps with a 300 gr with h4198.I LOVE my 45-70,s.Mounting a ballistic plex on a 45-70 is just way cool,should generate alot of grins and maniacal laughter.Take care GRPB.

Yea we are off topic here....

Yea I knew that the contender and the old 94 wins were kind of the middle ground as far as action strength. But I had no idea guys where getting that kind of velocity's out of the Rugers. That would change the rules somewhat for that cartridge.

I don't know if I could hit anything with that contender pistol of mine or not. but it sure makes you smile when you pull the trigger.

And as far as off topic, here is what I figured with my burris

1.55 mils
4.5 mils
7.525 mils
11.06 mils

Tyler when u convert i always remember that the MOA # is smaller than the inch per hundred yard (IPHY) #. The way i remember it is that MOA has less letters than IPHY, so the # will also be smaller--might help some.

 

[Tyler Kemp]

H4198 is THE powder for the 45-70. You could probably get 2600 fps from a 300 grainer in a Ruger with a longish barrel.

Or 2550 from the 325 LE bullet.
