What scope do you use for .300 Whisper?

[jripper]

I use a bushnell holosight II. However, I can not say that it is ideal for changing from super sonic to sub sonics. Check Horus vision. Horus uses a grid system, and give computer software with their scopes that tell you what grid to use, at what distance. My friend has one he uses for his long range rifle, and can compensate from 100 to 500 yards without changing his settings.
They may have something that would work for you.

Hi there,
I'm having a custom mildot reticle installed on my 2.5-8x36 leupold & ballistically matched for subsonic 240gr Sierra MK's to give 50yard hold points out to 300 yards. Should make for accurate field shots when combined with my lazer range finder.

Murmur, how much is that modification going to cost?

Joel, thanks for the suggestion. I looked through a Horus Vision once, and the reticle was far too busy for me. And far too expensive. But that probably really would work.

My suggestion is that you get a scope like the Leupold Long Range Tactical with M1 knobs and a mildot reticule.

With the 300 Whisper (subsonic) 220 gr SMK you will need from 36 to 39 MOA depending on atmospherics to accurately engage a 300 yd target.

I'm thinking of getting the SWFA Super Sniper in 10x for $299.

Also, having customs dots being set up on your reticle at different ranges can be good, I am not sure of the reliability of the system when atmospheric conditions changes, specialy at the longuest ranges (past 150yards).

I am playing with a 22lr ( with silencer and sub ammo) up to 200 yards, and I find that an accurate scope with precise and positive 1/4moa knobs + a laser rangefinder are doing very well. But I can have a big difference past 80 yards between a warm summer (25 degres C) and winter (+5 degrees C).

I do not know how the conditions changes can affect a larger whisper projectile but doing some tests before investing in a reticle that could become useless later seems a good idea.

I just got my Whisper upper with 10" barrel, and have been researching scopes and reticles. The .300 Whisper is difficult because it drops so quickly at sub-sonic velocities. It does have a very linear drop curve, though.

The best theoretical solution I have found for a reticle is the new Leupold SPR (Special Purpose Reticle). This offers Mil-dot marks at 2.5 mil intervals all the way out to 15 mils (vs. 1 mil intervals out to 5 mils in a standard Mil Dot scope). This gives you 215" (18 feet!) of drop path in the reticle.

According to my Oehler Ballistic Explorer program, the 2 1/2 mil marks closely match the 50 yard drop points for Corbon 220gr sub-sonic, all the way out to 400 yards, when sighted in with a 90 yard zero (this puts you 2.5" high at 50 yards, and 1.5" low at 100 yards). You could also zero at 100 yards, but this add a few inches of error at longer ranges.

The only problem with this reticle is that it is available as standard on just 2 Leupold scopes - the Mark 4 1.5-5x20 PR and MR models. Leupold will add it to any Mark 4 or Vari-X III scope for about $200 in their custom shop.

The advantages of this SPR reticle from Leupold are (in theory):

+ 2.5 Mil-dot Aiming marks calibrate to within 2.5" for Corbon 220gr sub-sonic load out to 400 yards

+ Max 2.5" error at every range can probably be corrected to < 1" error by slight power selector adjustment

+ 15 mils of drop marks instead of the standard 5 mils (yields Whisper aiming points out to 400 yards)

+ Has excellent range estimating capabilities on man-sized targets

+ Illuminated Reticle is possible with Custom Shop add of this reticle to illuminated scope

+ Even with the custom shop add, it's an all-Leupold product with single-source lifetime warranty

+ Re-usable/re-sellable for standard rifle calibers (Leupold pitches the SPR reticle for use with .223 and .308)

+ Can recalculate drop tables and use the 2 1/2 mil marks with super-sonic/any .300 Whisper loads

The disadvantages are:

- Expensive, about $200 to add SPR reticle in Leupold custom shop (but competitive with Premier Reticles prices)

- Needs range testing to confirm drop calculations

- Doesn't really work as well as 1 mil dots for standard rifle calibers or super-sonic Whisper loads


I have bought a used Mark 4 1.5-5x20 PR scope on eBay in order to test out the drop points with this reticle, and will post results when available. If this works, my plan is to buy a VX-III 4.5-14x50 Illuminated scope (#54922), send it to the Leupold Custom Shop for installation of the SPR reticle, and re-sell the low-power scope on eBay. I don't think you need the Target Knob version since the reticle should give you all your drops, at least for 220gr sub-sonic. I hate those things, anyway, since I always forget to reset them.

Here's the scope I bought used ($360) for testing:

And, here's the SPR reticle:

One last thought - the .300 Whisper 220gr sub-sonic at 400 yards still has more energy than a 45 acp at point blank range. I like to shoot gongs and varmints at long ranges. Even though 300 yards is usually considered the max, I believe that with a laser range finder, the right scope and a 1MOA rifle, you can make consistent hits in a 8" circle at 400 yards.

I apologize for the extended "Scope Nerd" discussion above, but thought some of you might find this useful.

I am going to buy a VX-I 4-12x40 from premier retical and have them install the RC-600 check it out

I plan on using the Leupold 3.5x10x40 LR M3. I filed the stop off the knob and use a 30 moa badger base. This should give me about 60-70 moa adjustment from zero. The 1moa clicks are the ticket I think.
