My 30-06 semi-auto is a late-model Remington 7400 - built in 2002, but it's had a lot of ups and downs until now it's all ups and it's a shooter.
P.S. Initially, the first 50 rounds produced jams every third round, so I went to work on it by bedding the action / stock / installing a LimbSaver Barrel De-Resonator / adjusting the trigger to 3 lbs., and dry-firing / working the action 1,000 times.
A major and very thorough cleaning of the action and chamber was performed. Did I say take your time and pay close attention to detail in cleaning the action / chamber / bolt?
Afterwards, the 7400 30-06 has not jammed in the last 200 rounds and is shooting groups that vary between 7/8" and 1 1/8" off a benchrest and 1 3/4" to 2" groups offhand - using 180-gr. Federal Solid Base rounds.
Speer Hot Core 165-gr. were slightly more accurate and shot the smaller groups, with the 180-gr.'s being the largest, but not my a large margin.
Will try some Nosler Ballistic Tips and AccuBonds next.
P.S. Groups definitely opened up when the barrel's hot, but no accuracy problems in firing a quick 4-round magazine from a cold barrel, as in the worst case hunting situation.
I've also had very good luck with the Speer Hot Core in my '06 but, I can't get them to shoot worth a darn in the 300wsm. It's too bad, they are a good performing bullet.
I've also shot several of the Accubonds. It doesn't seem to matter what size or weight. They shoot well consistently. Good job, Nosler.
I still prefer the 180gr Partitions in the '06. It just feels like the ideal combo.
Here is a tip that was passed along to me - and I have not tried it yet - but it looks (and smells) like it will work fine! The gentleman that gave it to me regards it as his secret weapon and he is a VERY successful hunter.
Get a fresh tarsal gland off of a decent buck - I think the ranker, the better. Taking them off of bucks that are hot in the rut seem to be the best because that is when the glands are the darkest and have the most "male buck" scent...
Take that gland and put it in a good,...
