New 29 grain NSA slugs (Edgun R5M)

they will chamber a little harder than pellets in my experience. I haven't tried to tune for them to see what accuracy was possible. I'd love to see what other r5m guys are seeing in their guns.

I posted earlier that nsa 29g worked well in Cricket 25. Hope to see edgun results.

I got a chance to try some of the new nsa 26.8 grain slugs. I just shot a few, but they fit in the magazine well and chambered very nicely. I would rather go heavier, but I now have a slug that fits. I feel like these have the potential to shoot, unlike anything that requires extra force to get into the barrel. Time will tell

I'm sure you'll get better results with the 26.8gr. if they don't require - extra force to get into the barrel.

Lead-in, Lead-in, and Lead-in. There I said it again and again.

A slug that's too long or short regardless how fast or it's weight won't be very accurate in most barrels. 

I've brought this up numerous times here on AGN. No one ever seems to talk about it though. 

Was really the only key aspect to getting my guns to shoot .25 cal. slugs accurately. 

One other thing I've seen is too slow of velocity can make slugs fly in a loop or small spiral to the target. 

Just my experience anyway........

I plan on throwing about 300 of those at an attempt to get a good tune. More if it seems to be almost there when I'm out. wish me luck and keep us posted on the 29's too.

Longshot, I'll be sure to clean it and lead it in with the slugs I'm tuning for. I don't know that it really matters, but I've heard it pays to start fresh with a new pellet/slug.

I think Long shot is referring to the lead in. The first part of your barrel the slug rests in when loaded. There shouldn’t be any pressure/force required to load your slugs. If there is your lead in is to tight. 
Accurate slugs that are correctly sized for your barrel usually load very smoothly. The length of the slug and where it lies when loaded in relation to the rifling is also crucial regardless of weight. 

Yeah I believe if I'm correct you want it just to touch the rifling when the bolt is closed. 

Well I selected the ammo to fit the leade. 29 grain was still too long. 26.8 grain chambers nicely. I'm also going to clean the barrel and lead it in with 26.8 grain slugs as a starting point for tuning these slugs. I think this covers both leade and lead. 

I did think the spelling was odd. I tried to google it but didn’t find leade. Thanks for pointing that out. Helps to be able to spell Good luck.

What Micheal said above. Powder burner terminological how ever spelled. 

In my barrels, a short slug = Ok to very good groups with about a 20% crazy wild flyer ratio. 

Too long of a slug (hard to close bolt) = No real group, just a shotgun pattern. 

I'm referring to a traditional machined barrel here.
