RL16 Throat Erosion

[ram]

I’ve read threads that say RL16 will erode throats and barrel faster than H4350, and it seems to come from a QL simulation that indicates 95% burn in the first 8” of barrel.

For those that use RL16 and H4350, have you experienced any real differences in erosion between the two powders?

Your cleaning methods, fire string intensity (tempo & # of rounds), the lot of steel in your specific barrel, will be far more influential factors in your barrels lifespan in terms of potential competitive precision capability.

It’s funny but it’s the opposite for me . H4350 always fucked up my throats quite fast.

I’ve runned RL16 for a while now and my throats are a lot better If I compare with my borescope.

Anytime any of this comes out, you’ll have the same amount of people saying h4350 wears faster, varget wears the fastest, RL16.......etc etc etc.

Thus far, I haven’t seen (doesn’t mean it’s not out there, I just haven’t seen it) any definitive evidence of any powder being more or less damaging in a meaningful way.

Probably just guessing since it often results in faster velocity. I shot the shit out of my 300WM, fairly hot 75 grains of H1000 resulting in ELD 225's at 2887fps. Each lot may vary so YMMV. But I added a PTD oversized bolt to my gun so I got a good look at my barrel. It showed wear but not bad. It takes a lot of work to smoke a barrel. And barrel are cheap IMO.

I had a 260 barrel go 3000+ on a strict diet of H4350.
My new barrel might see a R16 only, be interesting to see how long it lasts.

It might be based off of other factors.
Some will say Varget burn throats faster than H4895 and others not.
Those two powders (RL16 & H4350) have a very close heat rating output.
Someone here had a chart showing how hot powders ( not burn rate speed)
burned at. Those two were very close. Double based powders burned at a
much higher temp. than single based.
See if I can find it.

Found it. Scroll down to the chart. Post #21

Agree 100%!
