Snowpeak Something magical happened today... M60B a sleeper?

[Ed99]

Given the sucess Max115 had with slugs, I tried some NSA 17.5 slugs that I had in my M60B at a distance of 30m. Very accurate!! Just as good as my JSB 15.89 pellets. I'm only shooting them at 800 fps as my gun set up for shooting the JSB 15.89 at about 840 and I didn't change the reg or hammer. I can get 3 shots touching at 30m. I tried .217 and .216 diameter and in my rifle, the .216 shot a little bit better. I will have to try them at 50m and 100m later in the week and maybe even try a little tuning. You gotta like the 2x improvement in the BC of this little slug. Cuts you wind drift in 1/2. In comparison, the 17.5 gr slugs didn't shoot well in my FX Panthera's.

Every gun is different somewhat. I have done enough slugs shooting with my Impact MK2 with various weight and sizes, both NSA and H&N. But I have finally settled with the H&N 25gr Gen2 slugs and they are very accurate at 968 fps with the .218 head size.

I have shot some 21 and 23 gr H&N slugs in the M60B, but they didn't group like these NSA 17.5gr .217 head size. I think I just got lucky with the factory REG/HS spitting these slugs out at 895 fps.

There is always that one projectile that will shoot well in any particular gun. Just have to experience and try different REG/HS setting. Once you get lucky and found the one, then you will be smiling ear to ear with your successful and consistent impact to the intended targets at long ranges.

Just ordered some of these in the 5.52 head size - hope one of my .22's will shoot 'em like your M60B does -

Wish me luck and thank you for sharing this info.

Good grief! Thats a hammer!!

What do you think the 35 cal would get from this?

No problem. Let us know how it goes with the new ammo.

The NSA slugs arrived late yesterday, have only had time to take 3 shots across the chrony. They shoot fairly close to what 18.1 grainers do - first shot was 891, then 886, next shot 887. That will work, but only if they are accurate. Will post some target results as soon as I have time!

By the way, it has its first dove kill at 50 yards today. It has now claimed 51 rats, 1 starling and 1 dove lol. Once I get it to shoot well passed 75-100 yards, it will get more air time from my go-to Impact MK2 duty at the farm.

I've been calling my M60b's Impact Killers for a while now. Kinda tongue in cheek.

The 357 is anemic without a bunch of mods. Then shot count will suck too.

My 30 cal with reg at 170-180 bar is hitting 70 fpe for 2.5 mags. Everything is bone stock still.

I didn't have time to shoot groups, because I decided to change the reg on my bottle build P-Rod. I swapped a Gurlleu 2200 psi output for a custom Ninja Reg set to 2500 psi, hoping the upped pressure will get me over 900 fps.

I shot various spinners from 25 to 42 yards with FX 18.1 to make sure my zero was still good. Then switched to the NSA. I was nailing everyone of the spinners at 42 yards, including the smallest one, which is about the size of the nail on my pinky. Good enough for the kid.

The NSA .2175s chrony the same as an 18.1 as well, so that means the fpe will be slightly lower at the muzzle, but with a better bc they should retain more energy downrange?

Here's the chrony results: High of 953, low of 942, average 948, ES of 11, SD of 3. I am looking forward to seeing what the NSA will do to a tree rat noggin!
