So, i keep hearing people shooting the 44 grain jsbs at like 860 fps and im wondering why this weight and velicity are so popular. Is it an accuracy thing or air consumption?
44 grains at 100 yard benchrest, Why?
- Thread starter Stewy1412
- Start date
49gr for me from the Maverick. Bucks the wind and is stupid straight.
Working on 150 & 200y this summer.

And for the longest time selection for good firing pellets in 30 cal sucks. Well it still sucks but getting better. Most gravitated toward the 44. The fx versions are basically jsbs. Zan just came out within the last 6 months with their 56 gr version which some actually like.

Right now i have my impact tuned for the 50 grain jsbs at 900 fps and getting sub MOA pretty consistantly so i guess ill just stick with that then. I tried those Zan 56 grains and kept getting one out of every 5 shots were a flyer but i wasnt tuned for that weight

I been trying my hand at 100y bench with my Maverick VP .30cal, and I did so so with my second try at it, on a pretty windy day:
- JSB Hades
- JSB Knockouts
- FX Hybrid Slugs
- JSB Exacts 50.15gr
- FX Hybrids
- JSB Knockouts

Something to stew on, but every time I hear the comment made on “one every five” or every fifth shot is a flier, the common gun is the impact, and the discipline is bench or target shooting. I’ve caught myself enough times to realize, that maybe the plenum isn’t fully recharged. We all try and get off three to five quick cycle shots when the wind is in our favor, and it’s somewhere within those three to five shots one lands off in no man’s land and we label it that one flier out of five.
Just on my Impact I find I can rattle off three consistent shots for group and if I push for a fourth, it’s no where near the group. And this is shooting tethered to a tank, even. I’ve also found that counting to 12 and then pulling the trigger for each shot, my groups are very consistent.
Just thought I’d throw that out there

My Impact MK2 is also tethered @ 195 bars, I am considering that as a first Reg. Also tuning with a one-piece rest to minimize the human error, so the remaining is only = the elements.
I spent many thousand shots with CF sleeved liners last year and this year and recently went back to orings and let the liner free float. I got a feel the harmonics is more friendly and predictable.
Currently sizing my .25 pellets and I would do that with slugs as well if I could source the tool, but have not seen any MFG that does a good and precise job... I am talking 5 microns increments.

That's the reason that I got rid of the first regulator on my new MK3......I used the Saber Tactical fitting. The gun shoots more consistent now.....

It's a straight through fitting that replaces the first regulator on a MK3 Impact.....You take the bottle off and remove the fitting that the bottle screws on to...the first regulator is made inside that fitting, you replace that fitting with the Saber Tactical fitting and you no longer have a first regulator. It also increased my shot count also....I get over 80 shots per fill now.....

K&L made theirs shortly after the M3 came out. Been running it forever now with no issues. Slug impact. It's USA made as well, if that matters to you.

from my .30 uragan-1 @100yrds, does best with 50.15gr knockouts for grouping.
but its for crows not paper.....but if i needed to do paper, it shines !!

The theory of having two regulators is supposed to be more consistent between shots....but, the reality is my brand new out the box MK3 was not consistent until I removed the first regulator.

What was your spread before and after? After tuning my rifle, i get a spread of 4 with deviation of 2 fps with the 2 regs

I was getting between 10-25 sometimes more between shots.....and I also know how to tune the rifle. Since removing the first reg. it shoots very well now but I'm going to replace the second reg. with a Huma reg. as I don't trust the FX reg.

I have heard mixed reviews of them for sure, but mine has been doing well so far, about a year now, so maybe its like the "barrel lotery" but with regulators
