Suppressors First Suppressor - PTR

Rob01
If you wanted a good all around first can then check out the HuxWrx Flow Range 36. Can use it on a bunch of different platforms and even down to 9mm pistols. A flow through design so it will work great on ARs and bolt guns. It’s about 6.7” long and weighs around 12 ounces with the supplied attachment but I took that off and use another type so it’s about 10 ounces. It’s a pretty good do all can for $969. Worth a look if you were thinking of changing up your plan.

An item I would offer for consideration is the actual rangefinder one is using. I'm not talking about Sig vs Leica, I'm talking about the exact unit in your hands.... For example if I range and true my ballistics with my Sig rangefinder, I would never trust my buddies rangefinder even if it were the exact same model. Once I've trued my hardware system, any change in that system is another variable that has to be verified.

Very true. I have a Terrapin-X, and a buddy got an Sig Kilo 10K. We were ranging the same targets one day with them. At distances around 1000 yds, he was getting consistently about 4-5 yds more than me. At around a mile to 2000 yds it was 9-10 yds more than mine (that's enough to put you way off on your solution).

So, back at my own range with multiple targets out to 1626 yds, we had them professionally surveyed with modern surveying equipment that is accurate to about 0.5 inches. So now we have KNOWN distances that we can use to test range finders. It turned out that my farthest target (1626.27 yds in the survey), ranged consistently (and still does) at 1625 with the Terrapin-X, and 1635 with the Sig 10K. He sent the 10K back to Sig, they sent him a new one. It was better, but still off by 5 yds.

The Terrapin-X error shrinks to less than a yard at distances around 1200 or less. I assume that error grows to probably around -2 yards by the time you're out to 2100-ish, but can't confirm because we don't have anything surveyed that far. I'm just extrapolating the error at shorter distances to arrive at that figure - 0.5 yds short at 1219, 1 yard short at 1626, so presumably 2 yards short at 2100.

Here's the FUNNY part. He bought the 10K because he had a Sig Kilo 2400 that wouldn't range small targets much past 1000. Once we got the survey done, he tested it and accidentally found out that if he aimed the reticle a certain distance to the left (I think it was left), all of a sudden it started picking up all those targets he couldn't range before, AND, it was the most accurate of ALL the ones we tested - dead on (to the nearest whole-yard) with the surveyed distances at 740.xx, 1147.xx, 1219.xx and 1626.xx yards. He sold the 10K and knows how much "windage" to hold on the Kilo 2400 to account for the beam/reticle misalignment and get accurate returns from the target.

300 Norma H-1000 max?

For reference this is what they sent me for 245g LRHT since I switched to them anyway.

My load again is 75.02g h1000 which is on the low end of their charge weight. Any more and I get pressure. But my velocity is above max.

In Dec I shot a belly match. 26* and chronoed all rounds with garmin.

Stage
1 2732 avg 4.1 SD 10 rounds
2 2731 avg 6.0 SD 10 rounds
3 2718 avg 3.6 SD 10 rounds
4 2737 avg 6.0 SD 10 rounds
5 2737 avg 5.1 SD 9 rounds
Cold bore 2734 1 round

Yesterday I shot at 78* F and got
2749.9 5.2 SD 7 rounds

By my calc that’s .25 FPS / *F variation due to temp which seems pretty good to me.

Rimfire Barricade Matches and Range trends…

I generally try to avoid holds over 6-7 mils, just because it gets a bit difficult to get behind the reticle and keep my spot. Razor Gen 3. I will sometimes dial the middle target and hold over or under as required for the others. Personally I see the long bombs from solid-ish positions as almost free points. The targets are so big that unless I make a stupid mistake, they are hard to miss. This is in the context of occasional 1 MOA targets at 100. A 16” target at 400 is comparatively enormous.

Yeah the hold under and over is a good way and I do that a lot too in Rimfire matches. But given the need, a 10 mil hold is pretty easy especially with the 7D reticle.

Yeah a 16” at 400 is a good size but the wind at 400 versus 100 can be pretty rough. I like at least one long poke stage in a match. Just makes it fun and that’s why I shoot matches.
