Thompson Center Contender G2 Rifle in 30-30 winchester caliber
The Thompson Center Contender (TC) has been around for a long time in the form of a great hunting pistol
and carbine. Last year TC announced the new version of the Contender, the G2 Contender with several improvements over the old model,
The New Features include easier to opening, More clearance between the grip and the trigger guard,
incorporates a patented automatic hammer block safety with built-in interlock, and it allows shooters to
cock the hammer, lower it, and re-cock it without the need to break the action open again. In addition, you can also get a muzzleloading barrel in .45 or .50 caliber. See ODHA report on the muzzleloading barrel here..
The G2 Contender rifle is very compact and weighs only about 6 pounds. It features readily interchangeable
23" barrels, enabling the shooter to select from several different cartridge options; from 17 HMR and 22 LR
Match, 330-30 Winchester, 6.8 SPC, 45/70 Gov't., 45 cal muzzleloading, and 50 cal muzzleloading barrel
. In addition, all of the 161⁄4" and 21" barrels made for the old style Contender will readily fit the new G2
frame. Old style contender barrels must use the old style forend. G2 barrels are untapered and use the new G2 forend with two attachment screws.
30-30 Winchester in the TC Contender Carbine
When I first started looking at the new TC Contender Carbine I was most interested in the .45 caliber
muzzleloader and the 6.8 SPC. I really wanted to see how that new 6.8 SPC military cartridge would
perform in the 23" Contender barrel. Finding a barrel was easy, but finding ammo and/or brass was not. No
one seems to have any because it is all going to the military (like it should). I looked at the other barrels
available and decided the 30-30 Winchester would be the best for my needs and it is also very close to the
reported performance of the 6.8. Matter of fact, I will add that comparison to this report.
Things got off to a slow start when I put the new 30-30 Winchester barrel on the G2 Contender frame and it
would not cock. Took it off my Carbine frame and put it on an old style contender frame and it worked fine.
After some searching on the internet for possible cures and some close inspection, I found that the barrel
lugs were not locking into the frame all the way, preventing the G2 internal hammer block safety from
releasing. There is a small lever in the frame that springs forward when the barrel is opened that prevents
the hammer from being cocked. If the spring loaded locking lugs don't snap all the way into battery when
the barrel is closed, the hammer still can not be cocked. The cure was to hone down the top of the locking
lugs about a thousandth of an inch so the lugs would snap into battery and allow the hammer to be cock. Easy to do if you understand how the Contender works.
After getting the barrel fixed I used a Weaver mount to attach my Leupold VXII 2x7 scope. This scope will
be used for the 30-30 Winchester and the .45 muzzleloader. Using quick detachable rings and the same
type Weaver base on both barrels lets me use the scope on either barrel until I can get another scope.
There is basically no reloading data for the 30-30 Winchester except for low pressure loads with 150 gn or
170 gn round nose bullets. Sierra has some special loads for Contender pistols, but the data was for 14"
barrels and fast burning powers. I wanted to see what kind of energy and accuracy could get out of a 125 or
150 spitzer bullet in a 23" barrel. The advantage of a slick bullet like a Nosler Ballistic Tip over a round nose
bullet would make a lot of difference at 200 yards and the velocity should be higher in the longer barrel even with factory ammo.
My search did pan out when I went to Ken Waters' Pet Loads. If you haven't heard of Ken and the great
work he has done, get yourself a copy of his two volume masterpiece on reloading. Here a link to a source
on the net. Many of his articles from Handloader Magazine are contained in the Book. In his 30-30
Winchester update he lists many loads chronographed from a 24" Winchester M54 bolt action rifle.
Following his lead, I tried some of the powders that worked well for him and had pretty good results. Below
is the loading data for the 30-30 Winchester from the TC 23" barrel I chronographed and shot for accuracy on my initial trip to the range.

The Factory ammo is listed for comparison and fell short of advertised velocity by about 100 fps.
Seems the faster burning powders are best for this case even in longer barrels. I thought the slower burning
IMR4064 would help in a longer barrel but that is not true for the 30-30 Winchester. I was really impressed
with the 150 grain velocities. The 150 gn Ballistic Tip still has over 1200 foot pounds of energy at 300 yards.
Below is a table that compares my results from the TC Contender G2 Carbine in 30-30 Winchester with
published data for the 6.8 SPC and the 308 Winchester. Notice that the 30-30 Win handloads with the
Nosler Ballistic Tip bullet produced over 50% more energy at 200 yards than a 30-30 Winchester factory
load. Most of the gain in energy was because of the much better ballistic coefficient of the Ballistic Tip over
the Round nose factory bullet. If you change the bullet of the factory load with a muzzle velocity of 2300 fps
from a round nose to a Ballistic Tip, the energy at 200 yards would be increased to 1250 foot pounds. That
is roughly a 33% increase in energy! All the handloads outperformed the new 6.8 SPC, some by as much 40%.

I think the 125 gn bullet will perform better with the faster powders like AA2230 or RL7. Ken Waters got
fantastic results with RL7 but I do not have any on hand. Have to put that one on the shopping list. I also
want to get the groups down closer to 1 MOA. I may be able to do that using Honady 150 gn SST's or
dropping the powder charge a bit. The SST's shoot half inch groups in my .308 Winchester at full velocity.
Come back soon for more loads for the 30-30 Winchester in the TC G2 Contender Carbine.
UPDATE
Made it back to the range with new loads using Reloader 7 with 125 gn Nosler Ballistic Tips and Hornady
150 gn SST bullets. The velocity was a little better with Reloader 7 in both bullets weight. The loads listed
are max so DO NOT shoot these in a lever action! Not only did the velocity improve, but also the accuracy
with the Hornady SST's. 5-shot groups averaged 1.5" @ 100 yards. Looks like this will be the load for deer
in the fall. Come back in November for the picture of the Buck.
Good Shoot'n,
Chester
