It is very easy to search these topics - be sure to look there first if you can.

Rear spacer should be out when using 8MM - not modified. Not sure what you did there...

Front Spacer should be modified for 8MM or replaced with one already for 8MM

Romanian 8MM is regarded as the most reliable, but Yugo and Turk are around too. Check bullet lengths as 8MM varies by Mfg. Also be sure and check HEADSPACE before shooting the 8MM loads - imperative to be safe!

"24" 1919A4 barrel in 308 needs a .532" booster hole.
24" 1919A4 barrel in 30.06 needs a .718" booster hole.
24" 1919A6 barrel in 30.06 needs a .818" booster hole.
12-14" 1919A4 barrel in 308 needs a .718" or larger booster hole.
12" 1919A4 barrel in 30.06 needs a 1.190" booster hole, This is a real flame thrower "


Looks pretty accurate from my experiences.

True Dave, but it was not there originally nor was it needed.

My point was it (the rear stop/spacer) didn't need modifying for 8MM, and most people remove it. I ran my guns both ways too - no difference in function for me on my two 8MM guns. If JMB opted to not use it, then so did I, unless absolutely necessary :)

To each his own - whatever makes the gun work best! :)

Number2 - By standard booster I hope you mean .718 or larger :)
